Product Description
Michigan Motorsports LS3 Rocker Arms with Roller Trunnion Kit Installed
Fits 6.0L & 6.2L LS Engines – L99, L76, L92, L96, LS9, LSA, LY6, L77 Applications
Upgrade your valvetrain with Michigan Motorsports LS3 Rocker Arms with Roller Trunnion Kit Installed – the ultimate durability and performance upgrade for GM’s 6.0L and 6.2L LS-based engines.
These premium LS3 rocker arms feature an offset fulcrum specifically designed for use with LS3, L99, L76, L92, LS9, LSA, and other “square port” or “rectangle port” cylinder heads. Each set comes with new LS3-specific bolts, ensuring precise fitment and easy installation.
Whether you’re building a stock street engine or an all-out performance setup, replacing your OEM rockers with a true roller bearing trunnion setup is a must. Factory needle bearings are known to fail, often sending loose needles throughout the engine. Our upgraded 8620 steel trunnion system utilizes caged roller bearings to eliminate this weak point, delivering smoother operation, improved stability, and long-term reliability at high RPM.
Engineered for aggressive camshaft and cylinder head combinations, these rocker arms provide superior strength, reduced friction, and the peace of mind that your valvetrain is built to handle extreme conditions.

- Set of 16 brand-new LS3 rocker arms preassembled with roller trunnion upgrade
- Includes new LS3-style bolts for complete installation
- Offset fulcrum design – correct geometry for LS3/L92 “square port” cylinder heads
- Premium 8620 steel trunnion with caged roller bearings for superior strength

Upgrade
Had to replace a valve spring so decided to do them all & upgrade rocker arms as well while i was already there. Went in without any issues seems to be working flawlessly. Thanks
