RK 525GXW Chain
RK's GXW series chains are the top of the line extreme performance chains.
XW-ring chains are the best high-speed, extreme heat performance chains available today. The leading edge XW-ring seal is made of an advanced Nitrite Butadiene composite and features three contact lips and two convex inner/outer stabilizers.
This means three lubrication pools to protect against high-speed abrasion, heat build up, torsional flex and the loss of lubricant under these extreme conditions. As a result GXW chains provide the user with 10 times longer wearlife compared to standard chains, GXW chain seals are compression and distortion resistant to provide the ultimate in rotating efficiency.
