Product Description


Suitable for most after-market performance cams, these dual springs are recommended for high reving engines, and/or high ratio rocker arms.  These springs offer increased rates for elimination of valve float at higher RPM's, while reducing coil bind in high lift applications. They also offer increased safety in the event of spring breakage. Viton (.500) valve seals required.

NOTE: Requires machining of the valve seats and guides, that can be done by any machine shop for a few bucks.

Includes: 12 outer springs and 12 inner springs. Retainers and locks not included. Viton .500 valve seals required.
