Upgrade the valvetrain in your Gen V LT engine with Michigan Motorsports Gen V Rocker Arms with Bushing Style Upgraded Trunnion Kit Installed. This complete set includes 16 new OEM GM rocker arms that have been professionally upgraded with a bronze bushing style trunnion kit and paired with 16 upgraded Allen head bolts for installation. Designed for 2014-newer LT-based engines including LT1, LT4, LV3, L83, L86, L84, L82, L87, and L8T applications, this rocker arm set is a major reliability upgrade for stock rebuilds, camshaft upgrades, boosted builds, and high-performance Gen V LT combinations. The upgraded bushing design replaces the weak factory needle bearing setup, improves lubrication, increases load capacity, and helps protect the engine from bearing debris-related failures.
Key Features & Benefits
- Complete Gen V LT Rocker Arm Set: Includes 16 new OEM GM rocker arms with the bronze bushing style trunnion upgrade professionally installed, plus 16 upgraded Allen head bolts. This gives builders a complete, ready-to-install rocker arm package for compatible Gen V LT engine valvetrain service and performance upgrades.
- Bronze Bushing Trunnion Upgrade Installed: The upgraded bushing style trunnion kit is already professionally installed, eliminating the need to press apart and rebuild the rocker arms yourself. This saves installation time and gives you a clean, consistent, professionally assembled valvetrain upgrade right out of the box.
- Eliminates Weak Factory Needle Bearing Risk: Factory-style rocker bearings can fail, especially with more aggressive camshafts, and send damaging debris through the engine. This bushing trunnion design removes the weak needle bearing failure point and helps protect the oiling system, bearings, and internal engine components.
- C932 Bushing Material with Oil Feed Grooves: The special C932 bushing material is lubricated through oil grooves at two locations on the trunnion, continuously feeding oil to the bushing surface. This design promotes smoother operation, excellent lubrication, and long service life in demanding Gen V LT valvetrain applications.
- Built for Stock & High-Performance LT Engines: Recommended for stock engines, cammed combinations, boosted LT4 setups, truck builds, and aggressive Gen V LT performance applications. The bushed trunnion design offers dramatically higher load capability than needle bearing setups and can operate smoothly at higher RPM levels.
