Your cart is empty.PRW sportsman steel roller tip rockers are the ideal choice for a large cross-section of engines; whether it is a mild street rebuild or the performance requirements of off-track, circle track, and drag racing. The PRW 4340 chromoly steel rocker bodies feature a longer pivot slot for higher lift camshafts and are much stronger than die cast aluminum or stamped steel, so rocker arm flex is negligible. The roller tip minimizes scrubbing (the result of the valve stem pushing hard against the valve guide), reducing friction and freeing up an additional 15 to 30 horsepower over stock rockers.

BEWARE...Amazons listing of this item is incomplete. You must have pushrod guideplates on your heads to use these rockers. This is not stated in Amazons description. By the time I decided to install the rockers, 30 days had passed and Amazon basically said "Too bad so sad". I contacted the manufacturer and was advised that the Amazon listing is not complete. I'm now stuck with rocket arms that I cannot use.
