Suspension Bearing Kits

Has your swingarm developed play, or is the shock mount squeaking? Worn bearings and bushings can cause imprecise handling and uneven suspension. We stock bearing kits for swingarms, A-arms and front and rear shocks, so you can get the joints working without play again.

What bearing kits do in the suspension

The swingarm, A-arms and shock mounts pivot on shafts that typically run in needle bearings or bushings. When the bearings wear or rust, you can get play, squeaking and suspension that moves stiffly. A bearing kit replaces the worn parts in one go, but the contents depend on the kit – read the product description to see whether, for example, seals, spacers or bolts are included. You will find the arms themselves under control arms and the dampers under shock absorbers.

How to choose the right bearing kit

The most important thing is that the kit fits your vehicle and the joint you want to rebuild exactly:

• Model and year: Many kits are made for a specific model and year range, e.g. Pivot Works Swing Arm Kit for 02-04 Yamaha YZ125 or EPI A-Arm Repair Kit for 07-23 Honda TRX420.
• Location: There are separate kits for the swingarm and the front and rear shocks, so check which joint needs new bearings.
• Scope: Consider replacing several joints at the same time, as wear in one place can be linked to wear elsewhere in the suspension.

Installation and maintenance

Bearings are typically pressed out and in, which can require a press or a bearing puller as well as the correct tightening torque on reassembly. Grease the bearings during installation and inspect them regularly, especially after riding in mud, sand and water. The category also includes brands such as QuadBoss, BMR Suspension and Energy Suspension. If you are also working on suspension linkages or other suspension components, doing it at the same time can save you an extra teardown.

Frequently asked questions

How do I know if my swingarm bearings are worn?

Lift the vehicle so the wheel is off the ground and rock the swingarm or wheel sideways. Noticeable play, squeaking, or an arm that moves stiffly or notchy as the suspension travels can indicate worn bearings or bushings.

Can I reuse the old bolts and spacers?

That depends on their condition and on what the kit contains. If bolts or spacers are worn, scored or rusty, they should be replaced, as new bearings fitted on worn parts can wear out faster.

How often should suspension bearings be greased?

That depends on riding conditions and the manufacturer's instructions. If you often ride in water, mud or sand, it may be necessary to disassemble, clean and grease the bearings more often than when riding on dry terrain.
