Description:

Increase the RPM potential of your engine and get more power. EMPI's rocker shaft kits help eliminate rocker shaft side play that causes rocker arm galling as well as clip and washer failure. All necessary hardware is included. Best when used with swivel foot adjusters.

P/N 21-2309-0 includes precision ground high strength shafts, with solid steel center spacer and shims.

P/N: 21-2308-0 is similar to P/N: 21-2309-0 but has a floating aluminum center spacer which allows for "fine tuning" of rocker arm geometry and positioning.
