Texas Speed (TSP) GM LS Rocker Arm Trunnion Upgrade Kit w/ Bolts
OEM rocker arms are prone to failure, which can result in needle bearings being dispersed through the engine. The TSP rocker arm trunnion upgrade kit replaces the OEM needle bearings with captive bearing design. This trunnion upgrade kit also allows for 360 degree rotation and eliminates the travel stops (which create problems with higher lift camshafts) in the original OE rocker design.
- Upgrades stock LS series rocker arms w/ captured roller trunnions for modified applications
- Recommended when upgrading to a higher lift camshaft for durability and longevity
- Works on any LS-based rocker arms
- Includes New Bolts
- Does Not Include Socket
