Upgrade Your Stock LS Valvetrain
Stock LS style rocker arms were not designed for high spring pressures and high RPMs, usually causing the factory cageless trunnion needle bearings to fail and fall out of the rocker arm. An event like this can send the bearings through your engine causing catastrophic failure. Made from quality cast alloy steel to OEM specifications these rocker arms are simple to install as they are designed to be a drop-in replacement for your stock LS cylinder heads with zero modifications needed. Increase performance, protect your engine and your wallet with JEGS LS-Series Rocker Arms.
