Overview

  • Pre-Assembled Rocker Arms with Enhanced Trunnions - Our kit features 16 fully assembled rocker arms, each upgraded with premium trunnions, ensuring a straightforward installation process and immediate performance benefits.
  • Enhanced Valve Train Stability - By reinforcing rocker arm strength and reliability, our upgrade promotes smooth valve operation, maximizing engine performance and longevity, even in high-performance setups. 
  • Premium Construction - Each rocker arm incorporates a high-quality 8620 steel alloy trunnion and caged roller bearings, replacing the factory’s cageless needle bearings. This design ensures optimal load distribution and minimizes the risk of bearing failure, safeguarding your engine from potential damage.
  • High-Performance Trunnion System - Equipped with robust trunnions and precision-engineered caged roller bearings, this system is built to endure high RPMs and aggressive cam profiles, providing exceptional durability under demanding conditions.
  • Superior Durability and Reliability - The upgraded components address common failures associated with stock LS1 rocker arms, significantly reducing wear and enhancing overall engine longevity.

Engineering details

The detail is in the pivot.

The rocker arm pivots around its trunnion to transfer pushrod movement to the valve. The installed trunnion and bearing assembly forms the supported pivot at the centre of each rocker.
