Collection: Chains

RK’s sealed-ring chains offer less torsional friction and increased high-stress, high-speed performance.
From the beginning of a race to the end, RK’s sealed-ring chains deliver more consistent horsepower to the ground than non-sealed chains.
The nitrile butadiene seals ensure that lubrication stays inside the chain while keeping dust and dirt out.
Most RK chain seals have lubrication pools that protect against high speed abrasion, heat build up, torsional flex and loss of lubricant under extreme conditions, resulting in longer life for the chain and sprockets.
