Texas Speed & Performance Rocker Arm Sets with Upgraded Trunnion Kit

A must-have upgrade for any high-performance heads and cam setup, the Texas Speed & Performance Rocker Arm Sets are built to handle the added stress of aggressive valve train combinations. These sets start with OEM GM rocker arms and are enhanced with the TSP retro-fit trunnion kit for significantly improved durability and reliability.

The TSP trunnion kit replaces the factory powdered metal trunnions and cageless needle bearings with a high-strength 8620 steel alloy trunnion and caged roller bearings. This design drastically reduces the risk of failure common with OEM LS1-style bearings, which can scatter needle bearings throughout the engine when they let go. With this upgrade, you gain peace of mind and enhanced longevity in high-RPM, high-stress applications.

Available Fitments:

Cathedral Port Engines: LS1, LS2, LS6 (Standard Rockers)
Rectangle/Square Port Engines: LS3, L92, L99, LS9, LS7 (Offset Rockers)

You can also choose to upgrade your set with CHE’s bushing-style trunnions for even greater strength and reduced deflection under load — a popular option for extreme-duty applications and professional race builds.

Simply select your rocker arm style and trunnion upgrade option from the dropdown above and give your LS valvetrain the reliability it deserves!
