Product Description
Michigan Motorsports Gen V LT Rocker Arm Trunnion Kit
Fits Gen V LT1, LT4, LV3, L83 & L86 Engines | Captured Roller Bearings | Complete 16-Rocker Upgrade Kit
Upgrade compatible Gen V LT factory rocker arms with the Michigan Motorsports Rocker Arm Trunnion Kit. This complete retrofit kit converts stock rocker arms to a captured roller bearing configuration, replacing the factory trunnion and bearing arrangement with upgraded trunnions, roller bearings, retaining rings, and stronger installation bolts. The result is a more stable rocker arm pivot assembly for stock rebuilds, camshaft upgrades, boosted applications, nitrous builds, and high-RPM valvetrain service. Installation can be completed with a press or suitable vise and basic hand tools, with instructions included.
Key Features & Benefits
- Complete 16-Rocker Trunnion Upgrade: Includes the trunnions, roller bearings, retaining rings, installation hardware, and bearing-press washers needed to upgrade all sixteen rocker arms on one compatible V8 engine.
- Captured Roller Bearing Configuration: Converts compatible factory rocker arms to a captured roller bearing setup designed to provide smooth rocker arm movement and help retain the roller bearing assembly during operation.
- More Stable Rocker Arm Pivot: The upgraded trunnion arrangement provides added rocker arm stability for stock engines, performance camshaft combinations, boosted builds, nitrous applications, and higher-RPM valvetrain use.
- Upgraded Shorter Rocker Bolts Included: Includes sixteen upgraded bolts that are slightly shorter than factory bolts to help prevent bolt protrusion into the intake ports on compatible applications.
- Built for Demanding LT Engine Builds: Suitable for everything from stock engine service to high-output turbocharged combinations, allowing factory rocker arms to be upgraded without the cost of a complete aftermarket rocker system.
