Best Suspension For Dirt Bikes: Compare Rear Shocks and Front Forks

#1 · Best Overall

1. AuryngMD 350mm Rear Shock

• Compatible with Vehicle Type: ATV, Dirt Bike, Golf Cart, Motorcycle
• Material Type: Alloy Steel

Best for: Longer 350 mm rear-shock upgrade.

Why it ranks #1: Its 350mm eye-to-eye length, 10mm mounting hole, 12mm spring, and 800-pound maximum load suit riders needing this specific rear-shock size.

The 350 mm eye-to-eye length and 12 mm heavy-duty spring make this AuryngMD rear shock a longer, clearly dimensioned option for compatible dirt and pit bikes. Its stated 800-pound maximum load per shock and high-quality damper are intended to support smoother handling over rough terrain.

The 350 mm eye-to-eye length, 385 mm total length, and 10 mm mounting hole give buyers several measurements to compare against an original shock. A 12 mm spring works with the damper to absorb bumps and reduce vibration, according to the supplied description. The 800-pound maximum load applies per shock. Listed applications include dirt bikes, pit bikes, motorcycles, ATVs, go-karts, and buggies, with named brands such as Thumpstar, Apollo, Orion, and WPB.

Skip it if you need a shorter 290 mm rear shock; HARIFOGER's 290MM is listed at that eye-to-eye length.

This suits riders seeking a longer rear shock with a stated spring size and load rating for a compatible bike, ATV, or buggy. Compare its 350 mm eye-to-eye length and 10 mm hole before installation.

#2 · Best Adjustable Preload

2. Oumurs 285mm Rear Shock

• Compatible with Vehicle Type: Motorcycle
• Material Type: Alloy Steel, Aluminum

Best for: Adjustable 285 mm pit-bike shock.

Why it ranks #2: The 285mm eye-to-eye length and tool-adjustable spring preload suit compatible pit bikes, while the 10mm eye diameter gives a useful fitment check.

A tool-adjustable spring preload sets this 285 mm OUMURS rear shock apart, letting riders change preload for a different riding feel. The 10 mm eye diameter and stated compatibility with Honda CRF50, XR70, and several small replica bikes provide specific starting points for checking fit.

The 285 mm eye-to-eye length and 10 mm eye diameter give you two measurements to compare with the original shock before buying. Once installed, the tool-adjustable spring preload can be set longer or shorter to alter the riding experience, according to the listing. OUMURS also describes bump filtering and impact absorption for a more controlled ride. Its stated applications include some quads, pit bikes, buggies, and projects, provided they use the same 285 mm eye-to-eye size.

Skip it if you need front suspension; WPHMOTO's TM805 is a pair of front forks for listed small dirt bikes.

A useful candidate for pit-bike and project owners whose existing shock measures 285 mm eye-to-eye and 10 mm at the eye. Preload adjustment adds a setup option, but the listed dimensions govern fit.

#3 · Best Front Fork Set

3. WPHMOTO Front Forks

Best for: Small-bike front-fork replacement.

Why it ranks #3: This is the lineup’s dedicated front-suspension pair, with 710mm length, 33mm upper legs, and fitment listed for several small dirt-bike sizes.

This WPHMOTO set supplies a pair of 710 mm front forks with 33 mm upper legs, giving buyers concrete dimensions for a small-bike front-end replacement. The listed 12 mm front axle fit and applications spanning 110cc, 125cc, and 140cc dirt bikes help define its installation target.

Because the package is a left-and-right pair, it addresses both sides of the front end rather than a single fork. The 710 mm length and 33 mm upper-leg diameter offer key measurements to compare with the existing assembly, while the stated 12 mm front axle fit narrows the installation match. The description names Chinese dirt bikes and models including Apollo, SSR, Coolster, CRF50, XR50, and CRF70. Verify these dimensions against the bike’s setup before selecting it.

Skip it if you need a rear shock rather than front forks; OUMURS's 285 mm shock is a listed rear-suspension option.

For owners replacing the front fork assembly on a compatible small dirt bike, the paired forks and stated axle and tube dimensions are practical selection details. The 12 mm axle fit is a key boundary.

#4

4. AuryngMD 320mm Rear Shock

• Compatible with Vehicle Type: ATV, Dirt Bike, Go Kart, Motorcycle, Pit Bike

Best for: Small-bike replacement shock.

Why it ranks #4: Its 320mm eye-to-eye length, 10mm mounting hole, and 800-pound maximum load suit buyers matching the specified size for small bikes.

An 800-pound-per-shock load rating pairs with a 320 mm eye-to-eye length, giving buyers a defined starting point for replacing a worn rear shock. The listed 10 mm mounting hole and compatibility with common 110cc, 125cc, and 150cc bikes help narrow the match before installation.

The 320 mm eye-to-eye measurement and 10 mm mounting hole give you two concrete dimensions to compare with an existing shock, while the listed total length is 355 mm. Its 800-pound-per-shock maximum load and 11 mm spring thickness are relevant when choosing a replacement for a compatible small bike. The stated applications extend beyond dirt and pit bikes to ATVs, quads, go-karts, and scooters, so its usefulness depends on matching the actual vehicle and mounting dimensions.

Skip it if you need a front-fork assembly; WPHMOTO's TM805 is a listed pair of front forks.

For a rider replacing a rear shock on a compatible small dirt or pit bike, this offers useful dimensions and a stated load rating. Check eye-to-eye length and mounting size; it is one shock, not a fork set.

#5 · Highest Listed Load

5. HARIFOGER 290mm Rear Shock

• Compatible with Vehicle Type: ATV, Motorcycle
• Material Type: Acrylonitrile Butadiene Styrene, Aluminum

Best for: High-load 290 mm rear shock.

Why it ranks #5: The 290mm rear shock lists a 1000-pound maximum load per shock and 40mm travel, for buyers whose original part matches its mounting size.

A stated 1,000-pound maximum load per shock distinguishes this HARIFOGER 290 mm rear unit for buyers comparing load ratings. Its 10 mm eye diameter, 11 mm spring diameter, and 40 mm travel length add concrete sizing details for checking a dirt or pit bike’s existing suspension.

The 290 mm eye-to-eye length and 10 mm inside eye diameter give you specific mounting measurements to compare before choosing this rear shock. Its listed 40 mm travel and claim of improved damping management describe the suspension role, while the 1,000-pound maximum load per shock is a stated rating, not a vehicle capacity. HARIFOGER lists common 50cc–250cc pit and dirt bike applications, as well as ATVs and motorcycles with matching mounting dimensions.

Skip it if you need a 280 mm rear shock; HARIFOGER's B280MM is the listed shorter-length option.

This suits buyers seeking a single rear shock for a 50cc–250cc dirt or pit bike whose measurements match. Its load rating and travel are specified, but the 290 mm length remains the fit boundary.

#6

6. HARIFOGER 280mm Rear Shock

• Compatible with Vehicle Type: ATV, Motorcycle
• Material Type: Acrylonitrile Butadiene Styrene, Aluminum

Best for: Compact 280 mm high-load shock.

Why it ranks #6: Its 280mm eye-to-eye length, 10mm eye diameter, and 1000-pound maximum load target riders whose small-bike replacement matches those dimensions.

A 1,000-pound maximum load per shock gives this HARIFOGER rear suspension a clearly stated rating in a compact 280 mm package. Its 10 mm inside eye diameter and 40 mm travel length add useful measurements for buyers comparing a replacement against a small dirt or pit bike’s existing setup.

The 280 mm eye-to-eye length and 10 mm inside eye diameter help narrow the mounting match, while the 40 mm travel length describes the listed suspension travel. HARIFOGER states a maximum load of 1,000 pounds per shock and says the unit provides smoother riding and damping management. Common applications include 50cc–250cc pit and dirt bikes, along with ATVs and motorcycles using matching dimensions. The package contains one rear shock, making it a single-unit replacement.

Skip it if you need a 290 mm rear shock; HARIFOGER's 290MM is the listed alternative with a longer eye-to-eye measurement.

A candidate for small dirt- and pit-bike owners who need a 280 mm rear shock and can use the listed 10 mm eye diameter. It is a single unit, and mounting dimensions remain decisive.

#7

7. GZYF 320mm Air Shock

• Compatible with Vehicle Type: ATV, Motorcycle, Quad
• Material Type: Aluminum,Steel

Best for: 320 mm reservoir-style rear shock.

Why it ranks #7: The 320mm air shock includes an aluminum reservoir tank, but its stated fitment emphasizes street bikes, scooters, and ATVs rather than dirt bikes.

A CNC aluminum reservoir tank distinguishes this GZYF air shock, while its 320 mm length gives buyers a concrete starting point for a rear-suspension replacement or modification. The listing covers dirt bikes, 150cc–750cc street bikes, scooters, mopeds, and quad ATVs.

The 320 mm length is a useful comparison point when checking a current rear shock, and the listing advises using eye-to-eye distance as the main fit basis. Its CNC aluminum reservoir tank is a named construction feature, alongside aluminum and steel materials. Stated applications include dirt bikes, street bikes, scooters, mopeds, and quad ATVs. The supplied information does not give a specific eye-to-eye measurement, so the listed 320 mm figure alone may not settle the mounting match.

Skip it if you require a documented 320 mm eye-to-eye measurement; AuryngMD's MDJZ320121003 lists that dimension explicitly.

This is for buyers considering a reservoir-equipped GZYF shock for a listed motorcycle, dirt bike, scooter, or quad application. The 320 mm title length helps, but confirm the relevant mounting measurement from product details.

#8

8. GZYF 15.7-inch Air Shock

• Compatible with Vehicle Type: Golf Cart
• Material Type: Steel, Aluminum

Best for: Long-shock street-bike conversions.

Why it ranks #8: Its air-shock format and stated dirt-bike compatibility may suit a matching application, but the listing stresses eye-to-eye measurement and broad street-bike fitment.

At 15.7 inches, this GZYF air shock targets buyers seeking a longer rear-shock option for listed 150cc–750cc street bikes, scooters, mopeds, and ATVs. Its steel-and-aluminum construction gives the product a defined material specification, while the listing emphasizes eye-to-eye distance as the key fit check.

The 15.7-inch length gives buyers a stated dimension to compare against an existing shock, and the listing specifically calls eye-to-eye distance the main basis for judging fit. That makes measuring the current setup central to choosing this replacement or modification part. Steel and aluminum are the specified materials, and the listed applications span street bikes, scooters, mopeds, and quad ATVs. The listing also mentions dirt bikes, but the supplied fit information does not name particular dirt-bike models.

Skip it if you need a documented 320 mm eye-to-eye dimension; GZYF's 45YF071-AM lists a 320 mm length.

This is for buyers considering a longer shock for a listed street bike, scooter, moped, or ATV application. Its 15.7-inch length is useful context, but the missing eye-to-eye figure limits fit comparison.

#9

9. Nhdhxie Rear Suspension Absorber

Best for: Adjustable-damping small-bike shock.

Why it ranks #9: The listing gives 260mm and 280mm size options and aluminum construction, but lacks clear eye-to-eye and mounting measurements for confident dirt-bike matching.

Multiple damping settings are the central feature of this aluminum rear absorber, letting riders accommodate different stated riding conditions. The listing identifies a 260 mm option and compatibility with ATV, motorcycle, pit-bike, and CRF50/XR small-bike applications, though it supplies fewer detailed sizing measurements than several alternatives.

The aluminum construction is described as able to withstand road impacts, while multiple damping settings offer an adjustment for differing riding conditions. A reinforced mounting bracket is listed to support stable operation, and reduced handlebar vibration is presented as a control benefit. The title identifies this as the 260 mm version within a 260 mm/280 mm product title. Because the supplied details do not give eye-to-eye or mounting-hole measurements, buyers have limited dimensions for comparing it with an existing shock.

Skip it if you need listed eye-to-eye and eye-diameter measurements; OUMURS's B0830000115P specifies 285 mm and 10 mm.

This is for buyers prioritizing adjustable damping and aluminum construction on a listed small-bike or ATV application. The selected 260 mm version is identified, but limited mounting dimensions make comparison with the existing shock important.

#10

10. MEROCA 190mm Air Shock

• Compatible with Vehicle Type: Bicycle, Motorcycle
• Material Type: Aluminum

Best for: Four-way-tunable off-road bike shock.

Why it ranks #10: Its 190mm shock is primarily described for mountain bikes and e-mountain bikes, making it a poor match for conventional dirt-bike suspension needs.

Independent rebound, compression, preload, and air-pressure controls give the MEROCA RCT-2 four ways to tune suspension response. Its listed 200–300 PSI air-pressure range and 550 lb/in spring strength target full-suspension mountain bikes, downhill bikes, and e-mountain bikes tackling varied off-road conditions.

Rebound and compression controls let riders tune response characteristics, while preload and air pressure add further setup adjustments; the stated air range is 200–300 PSI. The 9 mm-thick coil spring is rated at 550 lb/in, providing another defined specification for matching the shock to a bike and rider setup. MEROCA lists full-suspension MTB, downhill, and e-mountain-bike use, plus e-motorcycles. This is a bicycle-oriented suspension option, so its applications differ from conventional small dirt-bike rear shocks.

Skip it if you need a conventional 290 mm pit-bike shock; HARIFOGER's 290MM is listed for dirt and pit bikes.

This fits riders seeking extensive setup control for a full-suspension MTB, downhill bike, e-mountain bike, or listed e-motorcycle. Its bicycle-focused applications are the key boundary for dirt-bike shoppers.
