LS/LT Rocker Arm Trunnion Installation Tool

GM LS/LT Valvetrain Component for Improved Valvetrain Performance

These valvetrain component are designed for GM LS/LT applications, helping improve valve lift, reduce friction, and support more responsive engine performance.

Built from performance-grade material, this rocker arm design balances strength, durability, and valvetrain stability for street performance, restoration, and upgraded engine builds.

The precision valvetrain design helps promote smoother rocker motion and more consistent valve control, especially when paired with compatible camshaft, pushrod, and valve spring combinations.

Configured where applicable, these rocker arms are built for proper fitment and reliable operation. Always verify rocker ratio, stud size, pushrod length, guideplate alignment, and valve spring clearance before installation.
