Designed to handle higher spring pressures and engine RPMs over stock, these LS1 rocker arms from Racing Power Company are forged from quality steel alloy and include caged roller bearings and 8620 steel trunions for superior durability and performance.
The R3070 LS1 rocker arms meet or exceed OE specifications and include one set of 16 rocker arms and new mounting bolts. This Racing Power Company kit is a 100% drop-in design for a hassle-free installation: just rotate the trunion with the flat recess facing up, then tighten bolts to 22 ft-lb following the factory procedure.
