RK 520EXW Performance XW-Ring Chain
520EXW is specifically designed for ATV/Quads and off-road vehicles and is the best high-speed, extreme heat, off-road performance chain available today. EXW chains were developed to survive the abrasive conditions that exist in hostile off-road environments. EXW features XW-Ring seals composed of Nitrile Butadiene with three contact lips and two convex inner/outer stabilizers. This means three lubrication pools to protect against high-speed abrasion, and the loss of lubricant under these extreme conditions.

- XW-ring chains are the best high-speed, extreme heat performance chains available today
