These rocker arms are a must have for any aggressive heads and cam combo and are the same rockers we utilize on our 1,000 hp Turbo Motor. We utilize LS rocker arms and install new LS1 rocker arm retro-fit trunion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunion with a premium 8620 steel alloy trunion and caged roller bearings for added durability. The caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS1 needle bearings, which can send loose needles throughout the engine upon failure.
Fits all these applications: LS1/LS2/LS6/ LR4 Vortec 5300 LM7 L59 LM4 L33 4.8/5.3/5.7/6.0/ Engines This kit includes: 16 LS Series Rocker Arms 16 rocker arm trunnions- LS-type retrofit 32 rocker arm bearings- LS-type retrofit 32 rocker arm retaining rings- LS-type retrofit 16 bolts for LS trunnion kit. Install the upgraded rocker arms to the cylinder heads using the new socket head cap screws supplied.
Be sure to rotate the trunion so that the flat recess side of the trunion's center hole faces upward (the socket head cap screw must seat against this recessed flat side of the hole). Tighten the cap screw to a value of 22 ft-lbs, following the OE installation procedure.
