The stock bearings have a tenancy to fail. 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 stock rocker arms and new LS 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 new design from utilizes caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS needle bearings, which can send loose needles throughout the engine upon failure.

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.Condition: New, Brand: michigan motorsports, Manufacturer Part Number: 25200-01+25400-02, Interchange Part Number: trunnion
