Dual High-Rev Springs

Dual springs are used in high performance applications to prevent valve float at high RPMs.

This is a brand new set of 8 dual high-rev springs for increased RPM and performance. Made from special silicone spring steel. Prevent engine damage due to valve float or worn out weak valve springs. They can be used as intake or exhaust springs in almost any VW Type 1 head casting.
