This product was added to our catalog on May 27, 2004.This is a set of optional 1.1mm clutch springs. This is a common clutch spring for RB Concepts WS7 and WS7II engines. The stiffer the spring, the later the clutch will engage allowing the engine to spool up to a higher RPM range before the clutch comes on. The later the clutch engages, the more the clutch will slip causing the clutch shoes to wear out more quickly.
