Rocker Arm Trunnions

Replaces stock needle bearings with upgraded trunnions, reducing the risk of catastrophic failure and improving long-term valvetrain stability.

Bolts

For LS7 engines, the supplied bolts are too long due to the pedestal being built in, so you just reuse your factory rocker bolts. For the rest of the other engines the supplied bolts will work.

Rocker Arm Bearings

Perfect for high-horsepower builds, aggressive camshaft upgrades, and boosted setups where reliability and durability are critical.

Rocker Arm Retaining Rings

These LS Series retrofit trunion kits are designed to convert stock LS Series rocker arms into captured roller trunions for high-rpm race applications.
