Product Description

The COMP Cams 13702-KIT is a retrofit trunnion bearing kit for GM LS-series rocker arms. Instead of replacing your rockers, this kit allows you to convert your existing LS rocker arms into a more stable, race-ready design - captured roller trunnions provide far better valvetrain stiffness and durability under high RPM.

The kit includes 16 trunnions made from high-strength 8620 steel, 32 precision caged roller bearings, and all the hardware (retaining rings, bolts, and washers) needed for installation. It's designed specifically to improve valvetrain stability on LS engines without the need for replacing the rocker arms entirely. Ideal for performance builds where durability, reliability, and high RPM capability are a priority.
