Each package contains two 3514634 bearings (35 mm × 64 mm × 37 mm) and two 3514635 bearings (40 mm × 74 mm × 40 mm), all forged from high‑grade carbon steel and heat‑treated for superior wear resistance. The set also includes four stainless‑steel ring clips that secure the bearings in place, preventing axial movement under heavy loads. With a compact package size of 4.96 × 4.96 × 3.5 inches and a weight of just over 5 lb, the kit is easy to store and handle. Designed to meet or exceed OEM specifications, these bearings fit a wide range of Polaris Sportsman models, including the 400, 450, 500, 570, 600, and 700 series spanning production years 2002‑2021.

These bearings are intended for the front and rear suspension pivots of Polaris Sportsman ATVs. Whether you are tackling rugged mountain trails, navigating muddy forest paths, or cruising on sand dunes, the steel construction provides the rigidity needed to absorb shocks while maintaining smooth articulation. Ideal for both recreational riders and professional racers, the kit supports high‑impact activities such as hill climbing, jump landings, and long‑distance trail riding. Installation requires basic hand tools; no specialized equipment is needed, making it suitable for DIY enthusiasts and professional mechanics alike.
