1. Whether you have a stock LS motor or a highly modified LS motor, replacing your rockers with a true roller bearing setup is highly recommended.
2. The stock bearings have a tenancy to fail.
3. 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.
4. 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.
5. 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.

The upgraded rocker arms and trunnion kit eliminate slop and play in the valvetrain, resulting in precise valve control and reduced valve train noise.


Haven’t fired up my 5.7 yet, but they seem decent enough quality for my budget build.


High quality and durability, reducing the possibility of failure
