A strong 14-inch air shock should match your vehicle’s required eye-to-eye length, offer suitable adjustment, and fit the load and mounting setup you need. The Zarko Adjustable Rear Air Shocks stand out for buyers who want a pair with both spring preload and air-pressure adjustment. This roundup compares six options for motorcycles, dirt bikes, ATVs, go-karts, and related vehicles, including sets rated at 540 pounds per shock and a single shock listed at 1,000 pounds.
These listings differ in important ways: some specify dimensions and adjustment ranges, while others provide limited technical detail or use a different mounting description. Check your existing shock’s measurements and mount style before choosing, and confirm whether you need one shock or a pair.
The Zarko Adjustable Rear Air Shocks are the strongest all-around choice in this group because they are sold as a pair, measure 360mm eye-to-eye, and offer both spring preload and air-pressure adjustment from 0.4 to 0.5 Mpa. Each shock is listed with a 540-pound maximum load, and adjustment tools are included. They suit buyers seeking a configurable pair for a compatible ATV, UTV, go-kart, or motorcycle.
Verify your vehicle’s mounting dimensions before ordering.

Detailed Reviews: Best 14 Inch Air Shocks
#1 · Best Overall
1. Zarko Adjustable Rear Air Shocks
- Material Type: Aluminum, Iron
- Compatible with Vehicle Type: ATV
Best for: Dual-adjustment suspension tuners.
Why it ranks #1: A 360mm pair with spring preload and 0.4–0.5 Mpa air adjustment; each shock is rated for 540 pounds and adjustment tools are included.
Spring preload and air pressure are both adjustable on this Zarko pair, letting buyers tune two suspension variables instead of relying on a single adjustment. Its 360mm eye-to-eye length targets vehicles requiring 14-inch rear shocks, and each shock is rated for a maximum load of 540 pounds.
The dual adjustment system combines spring preload with air pressure adjustment from 0.4 to 0.5 MPa, giving riders two listed ways to tune setup. A 360mm eye-to-eye length helps identify whether it matches the vehicle’s required rear-shock geometry, while the stated 540-pound maximum per shock clarifies the listed load rating. The package includes two rear air shock absorbers and adjustment tools. Zarko lists ATVs as compatible, alongside the title’s references to motorcycles, go-karts and UTVs.
- Spring preload adjustment
- Air pressure adjustment from 0.4 to 0.5 MPa
- 360mm eye-to-eye length
- Adjustment tools included
- The listing specifies ATV compatibility, but does not give vehicle-specific fit dimensions.
Skip it if you need listed compatibility with named motorcycle makes and models; AuryngMD MDJZ360121014 names several.
This pair fits buyers who want to tune both spring preload and air pressure on a vehicle requiring 360mm rear shocks. Check the mounting dimensions and vehicle fit carefully, particularly because the supplied specifications explicitly list ATV compatibility.

2. YC Yier Adjustable Air Shocks
- Material Type: Aluminum, Iron
- Compatible with Vehicle Type: ATV, Go Kart, Motorcycle, Scooter, UTV
Best for: Adjustable 360mm replacement pair.
Why it ranks #2: The pair measures 360mm eye-to-eye, lists 12mm eyes and a 540-pound load, and offers adjustable shock strength for compatible vehicles.
A 360mm eye-to-eye length paired with adjustable shock strength gives this YC Yier set a clear role: replacing or modifying a bike suspension setup that uses that measurement. The two shocks are listed for motorcycles, scooters, mopeds, ATVs, UTVs and go-karts, with a stated 540-pound load capacity.
The 12mm eye diameter and 360mm eye-to-eye measurement give buyers concrete dimensions to compare with an existing setup before installation. Adjustable shock strength allows tuning rather than relying on a fixed setting, while the listed 60mm working stroke describes the available travel. The pair is identified for a broad range of vehicles, including 110cc–750cc street bikes, scooters, mopeds and quads. Installation is described as easy, though the listing recommends having a qualified mechanic install them.
- Sold as a two-shock set
- 360mm eye-to-eye measurement
- Adjustable shock strength
- Listed 540-pound load capacity
- The listing does not specify an adjustment range for shock strength.
Skip it if you need both spring preload and air-pressure tuning; Zarko TTO853 lists those two adjustment methods.
This pair suits riders replacing or modifying a compatible motorcycle, scooter, moped, ATV or UTV suspension who want adjustable shock strength. Check the 360mm eye-to-eye and 12mm eye dimensions against your existing mounting points before choosing it.

3. AuryngMD 360mm Air Shock
- Material Type: Alloy Steel
- Compatible with Vehicle Type: Dirt Bike, Motorcycle, Pit Bike
Best for: Single-shock dirt-bike replacements.
Why it ranks #3: This single 360mm shock is listed with a 1,000-pound capacity and 12mm coil spring; its 180-day warranty is also specified.
A 1000-pound gas-suspension rating and 360mm eye-to-eye measurement define this AuryngMD rear shock for buyers replacing a single component. Its listing names 110cc–750cc models and several motorcycle brands, while the coil-over construction and 12mm spring dimension provide useful details for checking a potential fit.
The 360mm eye-to-eye measurement gives a direct reference for comparing the shock with an existing setup, and the listed 395mm total length adds another dimension for fit checks. A 12mm coil spring and 100mm air chamber identify the supplied construction details, while the 1000-pound rating is the title’s stated capacity. Compatibility includes dirt bikes, pit bikes and motorcycles, with several makes and 110cc–750cc models named. The included component is one shock, not a pair.
- 360mm eye-to-eye measurement
- 1000-pound capacity stated in the title
- 12mm coil spring
- Named compatibility with several motorcycle makes
- Only one shock is included, so a pair requires another unit.
Skip it if you need a two-shock package; Zarko TTO853 includes two rear air shock absorbers and adjustment tools.
This single shock suits buyers replacing one rear component on a compatible motorcycle, dirt bike or pit bike who can verify the 360mm fit. Account for the one-unit package if your repair calls for replacing both sides.

4. QuilxyzCart Adjustable Air Shocks
- Material Type: Metal
- Compatible with Vehicle Type: ATV, Dirt Bike, Go Kart, Golf Cart, Moped…
Best for: High-capacity shock pair shoppers.
Why it ranks #4: The listing identifies a two-pack of 360mm air-adjustable shocks and claims 850 pounds of capacity, with fit categories including dirt bikes and ATVs.
An 850-pound load figure in the title distinguishes this QuilxyzCart two-pack for buyers comparing stated capacity in 14-inch rear shocks. The listing also names a wide mix of vehicle types, from dirt and pit bikes to golf carts, ATVs and UTVs, making its declared application range unusually broad.
The 360mm length gives buyers a specific measurement to compare with a vehicle’s existing shock requirement, while the title’s 850-pound figure offers a stated load reference for evaluating the pair. QuilxyzCart lists compatibility with motorcycles, dirt bikes, pit bikes, go-karts, golf carts, mopeds, ATVs and UTVs. The package contains two shocks, so it provides a pair rather than a single replacement component. The supplied specifications do not explain adjustment settings or provide further mounting dimensions.
- Two 360mm shocks included
- 850-pound load figure in the title
- Listed for ATVs and UTVs
- Broad listed vehicle-type range
- The supplied specifications do not clarify whether 850 pounds is a per-shock or pair rating.
Skip it if you need listed eye-to-eye adjustment from 350mm to 360mm; 4into1 RR-EC-SC-350 specifies that range.
The QuilxyzCart pair may suit buyers whose vehicle uses 360mm shocks and falls within its listed applications, especially when the title’s capacity figure matters. Confirm how that rating applies and verify mounting details before selecting it.

View on Amazon#5 · Adjustable Length
5. 4into1 Remote Reservoir Air Shocks
- Material Type: Aluminum
- Compatible with Vehicle Type: ATV, Go Kart, Motorcycle
Best for: Adjustable-length reservoir shoppers.
Why it ranks #5: The pair adjusts from 350mm to 360mm and has silver anodized aluminum bodies and chrome triple-rate progressive springs, but uses eye-to-clevis mounting.
An adjustable 350–360mm eye-to-eye range lets these 4into1 remote reservoir shocks accommodate more than one length within the stated span. Silver anodized aluminum and chrome triple-rate progressive springs add specific construction details for buyers seeking a pair of adjustable shocks for a compatible motorcycle, ATV or go-kart.
The 10mm length adjustment, from 350mm minimum to 360mm maximum, gives buyers a defined range to compare with their mounting requirements rather than a single fixed length. Silver anodized aluminum is listed for durability and easy maintenance, while the chrome triple-rate progressive springs provide a distinct spring configuration. Sold as a pair, the shocks are listed for motorcycles, ATVs and go-karts. The description also notes a wide range of Honda motorcycle fitment and advises checking dimensions before purchase.
- Adjustable 350–360mm eye-to-eye length
- Remote reservoir design
- Chrome triple-rate progressive springs
- Sold as a pair
- The listed compatibility is limited to ATVs, go-karts and motorcycles.
Skip it if you need a stated 540-pound load capacity and scooters listed as compatible; YC Yier TM032 includes both details.
Choose this pair if your setup needs an adjustable length within 350–360mm and you value its listed aluminum construction and progressive springs. Its stated vehicle categories are motorcycles, ATVs and go-karts, so verify dimensions and application.

6. Progressive 412 Series Shocks
- Material Type: Steel
- Compatible with Vehicle Type: ATV, UTV, Motorcycle
Best for: 14-inch steel shock buyers.
Why it ranks #6: These 14-inch shocks are from Progressive Suspension and use steel, but the supplied listing gives no air-adjustment details or further fit measurements.
A 14-inch length and steel construction are the defining details of Progressive Suspension’s 412 Series 412-4086B shocks. Those specifications give buyers a basic size and material to compare with a replacement setup, while the product listing identifies motorcycles, ATVs and UTVs as compatible vehicle types.
The listed 14-inch size helps narrow the search for a shock of that length, and the steel material identifies its construction for buyers comparing component materials. Progressive Suspension names motorcycles, ATVs and UTVs as compatible vehicle types, but the supplied specifications do not provide eye-to-eye dimensions, load capacity or adjustment details. That leaves fitment and setup characteristics to verify against the vehicle and its existing suspension before ordering, rather than assuming the size alone settles compatibility.
- 14-inch shock size
- Steel construction
- Listed for motorcycle use
- ATV and UTV compatibility is listed
- The supplied specifications give no load capacity or adjustment details.
Skip it if you want a stated 540-pound capacity and adjustable shock strength; YC Yier TM032 lists both.
Consider the 412-4086B if its 14-inch size and steel construction match your requirements for a motorcycle, ATV or UTV. Its supplied listing is sparse on fit dimensions and adjustment, so those details remain important boundaries for selection.

View on AmazonAvoid the 14-inch measurement trap
A 14-inch label alone does not confirm that a shock will fit: compare the actual mounting centers and mount type with your vehicle’s requirements. Several listings give a 360mm eye-to-eye measurement, while the 4into1 Remote Reservoir Air Shocks specify eye-to-clevis mounting and a 350–360mm length range. Those measurements are not interchangeable without checking the vehicle’s hardware.
The YC Yier Adjustable Air Shocks list 12mm eye diameter, while the AuryngMD 360mm Air Shock also specifies a 12mm spring and 10mm mounting dimensions in its feature text. Treat dimensions as a compatibility check, not as proof of fit for every vehicle named in a listing.
Confirm the mounting style, bolt or bushing sizes, clearance, and required shock length before buying; a mismatch can prevent installation or change suspension geometry.
Check whether the listing is for one shock or two
The number of shocks in the package matters because the products here are not all sold in the same quantity. The Zarko Adjustable Rear Air Shocks and YC Yier Adjustable Air Shocks are pairs, as are the QuilxyzCart Adjustable Air Shocks and 4into1 Remote Reservoir Air Shocks. The AuryngMD 360mm Air Shock is listed as one shock, so a buyer replacing both sides should account for that difference.
Load figures also need careful reading: Zarko states 540 pounds per shock and describes up to 1,080 pounds across the rear pair, while the AuryngMD listing claims 1,000 pounds for its shock. The QuilxyzCart listing claims 850 pounds but does not clarify the basis in the supplied specifications.
Do not compare these figures as directly equivalent unless the manufacturer defines the load rating and application.
How to Choose 14-Inch Air Shocks
Length and mounting dimensions
Look for the measured mounting-center length and mount style, not just a 14-inch label. The Zarko Adjustable Rear Air Shocks, YC Yier Adjustable Air Shocks, and QuilxyzCart Adjustable Air Shocks list 360mm length; the 4into1 Remote Reservoir Air Shocks span 350–360mm and use eye-to-clevis mounting. YC Yier lists 12mm eye diameter, while AuryngMD gives 360mm eye-to-eye and additional mounting dimensions.
Choose a clearly documented 360mm eye-to-eye option when that matches your existing setup. Consider the 4into1 length range only when its clevis mounting is compatible.
If your current shock differs in length or hardware, verify fit rather than assuming these options interchange.
Adjustment and load information
Choose an adjustment setup and load rating that suit your vehicle and intended use, while checking how each listing defines capacity. Zarko specifies spring preload plus 0.4–0.5 Mpa air adjustment and 540 pounds per shock. YC Yier also lists a 540-pound load and adjustable shock strength, but does not give the same adjustment range.
QuilxyzCart claims 850 pounds, and AuryngMD lists 1,000 pounds for a single shock; the supplied details do not explain these ratings in the same way. Buyers who want explicit air-pressure tuning can favor Zarko, while those prioritizing a larger stated capacity may examine AuryngMD or QuilxyzCart and verify the rating’s meaning for their application.
Pair versus single-shock purchase
Check the package quantity before ordering so the purchase matches whether you are replacing one shock or a pair. Zarko, YC Yier, QuilxyzCart, and 4into1 are identified as pairs; AuryngMD is listed as one shock. The Progressive 412 Series Shocks listing does not state a package quantity in the supplied information.
A paired purchase suits a buyer replacing both rear shocks, while a single shock may fit a one-side replacement if the other side is appropriate to retain. Do not infer quantity from a product title alone when the specifications are unclear.
Confirm what is included and whether your vehicle requires matched shocks before completing the order.
Which 14-Inch Air Shocks Should You Choose?
Choose the Zarko Adjustable Rear Air Shocks if you want a 360mm pair with both spring preload and stated air-pressure adjustment, plus a 540-pound rating per shock. The YC Yier Adjustable Air Shocks suit buyers who want a pair and useful fit details, including 12mm eye diameter and a listed 540-pound load. For a single shock with the largest stated capacity in this selection, consider the AuryngMD 360mm Air Shock, while confirming its 1,000-pound rating applies to your setup.
The QuilxyzCart Adjustable Air Shocks offer a 360mm pair with an 850-pound claim. Choose the 4into1 Remote Reservoir Air Shocks only if eye-to-clevis mounting fits your vehicle.
The Progressive 412 Series Shocks provide the least air-specific detail here, so verify their construction and fit before choosing.
Frequently Asked Questions
How do I measure a 14-inch shock and confirm its mounting style?
Measure from the center of one mounting point to the center of the other, and compare that measurement with your vehicle’s specified shock length. Then check the mounting type, such as eye-to-eye or eye-to-clevis, along with eye diameter and available clearance. Confirm all dimensions against the product listing before ordering.
Should I replace both rear shocks at the same time?
Replacing rear shocks as a pair is generally preferable when both sides use matching shocks, because it helps maintain consistent suspension behavior. Check your vehicle’s service guidance and inspect both sides before deciding. Some listings here are sold as pairs, while others may describe a single shock, so verify package contents.
How should I set air pressure and spring preload for my vehicle and load?
Follow the shock and vehicle manufacturers’ instructions, starting with their specified settings for your application and load. Make adjustments in small steps and reassess handling and ride height in a safe setting. Do not exceed stated limits; for example, the Zarko listing specifies air adjustment from 0.4 to 0.5 Mpa.
What should I check before relying on a shock’s load rating?
Confirm whether the stated rating is per shock or for a pair, and whether it applies to your vehicle and intended use. The listings describe different capacities, including 540 pounds per shock for Zarko and a 1,000-pound rating for AuryngMD. Verify the manufacturer’s rating details and your vehicle’s requirements.
Can I use an eye-to-clevis shock if my current shock is eye-to-eye?
Only if your vehicle’s mounting points are designed to accept that configuration. The 4into1 listing specifies eye-to-clevis mounting, which differs from eye-to-eye. Compare both ends with your vehicle’s mounts and confirm dimensions and clearance before ordering; matching the nominal shock length alone does not establish compatibility.
Final Words
For a configurable pair with listed fit details, the Zarko is the strongest all-around option in this group: it is 360mm eye-to-eye, includes preload and air-pressure adjustment, and lists a 540-pound maximum load per shock. The YC Yier is another pair to consider. For a single shock, compare the AuryngMD’s stated capacity with your setup.
Confirm mounting dimensions and load requirements before choosing.
