All Balls Racing – Other UTV / Side-by-Side, including a fuel tap repair kit and throttle cable for the 03-13 Kawasaki KVF360A Prairie 4x4, rear differential seal only kit for the 15-23 Honda Pioneer 500, upper front shock bearing kit for the 15-18 Polaris RZR 4 900, front and rear caliper rebuild kits for the 17-21 Can-Am Defender 500, front differential seal only kit for the 19-20 Yamaha Wolverine X2, and a fork oil seal and dust seal kit for the 2020 Gas-Gas EC Ranger 300. Side-by-sides carry more weight and see deeper water than any quad, so the seals and pistons that keep dirt out are what determine how long the expensive parts last. A weeping differential seal drops oil level until the ring gear whines, and stuck caliper pistons drag the pads, cook fluid, and pull the machine off line under braking. These UTV seal and caliper rebuild kits restore proper sealing and free piston movement so brakes feel firm and the driveline stays quiet. Bench-bleed calipers and set differential fluid to level so the repair holds. Give us your model, year, and trim and we will confirm the right kit before you order.
