All Balls Racing – A-Arm & Control Arm Bushing Kits, including front lower A-arm bearing kits for the 2006 and 07-09 Polaris Sportsman 500 X2, front upper kits for the 01-14 Honda TRX500FA and 03-05 TRX650 Rincon, front lower kits for the 08-10 Polaris Outlaw 450 and 2019 Can-Am Outlander 450 6x6, plus related pieces like the 00-01 Honda TRX350FE power shift angle sensor. Worn A-arm bushings and pivot bearings are where ATV front-end slop starts: vague steering, uneven tire wear, clunking over ruts and ball joints that die early because the arm is no longer tracking true. These kits replace the pivot bushings, sleeves, seals and hardware as a matched set, so the arm pivots on fresh surfaces instead of egg-shaped bores. Rebuilt arms restore steering precision and keep alignment stable through mud and water crossings. Doing both sides at once keeps the front end symmetrical and saves a second teardown later. Note that many of these are sold as one kit per arm and two kits are required per vehicle. Send us your year, model and trim and we'll confirm the right A-arm bearing kit quantity before you order.
