Stainless Steel Prevents Rod Flex & Spring Bind For More Reliable Cycling

Hardened stainless steel guide rod won’t break or flex and bind the spring like the factory plastic rod. Helps prevent cycling problems, improves reliability and overall performance. Features a captured, ISMI chrome silicon flat spring that’s heat-treated, shot peened, and calibrated to the factory-spec 17 lb. weight. Steel Allen head screw and washer secure the spring to the rod, yet enable easy disassembly for spring replacement.
