Jims Valve Spring Kit Evolution Big Twin 1998-2004 Road Glide 1350K
Part Number: DS199523Description
If you're running a high-compression Evolution Big Twin with serious displacement, factory valve springs will let you down under sustained boost or aggressive cam profiles. The JIMS Valve Spring Kit replaces that weakness with a precision-engineered interference double-spring design that controls harmonic vibrations and maintains valve integrity even in severe applications. Built in the USA and trusted by builders who demand reliability at the edge of performance.
