Product Description
Michigan Motorsports LS3 Rocker Arms w/ Bushing Trunnion Upgrade
Bronze Bushing Trunnions | Maximum Durability | Complete LS3 Rocker Kit
Upgrade your LS valvetrain with Michigan Motorsports LS3 Rocker Arms featuring a high-performance bushing trunnion upgrade. Designed to eliminate the common failure points found in factory needle bearing rockers, this system replaces them with C932 bronze bushings that provide superior load capacity and lubrication. Ideal for both street and high-performance builds, these rockers are engineered to deliver long-term reliability, smoother operation, and increased durability under aggressive camshaft and high-RPM conditions.
Key Features & Benefits
- Bushing Trunnion Design – Replaces factory needle bearings with high-strength C932 bronze bushings, eliminating the risk of needle bearing failure and internal engine damage.
- Massive Load Capacity Increase – Bushed trunnions distribute load across a larger surface area, supporting significantly higher loads than traditional needle bearing designs.
- Enhanced Lubrication System – Dual oiling channels continuously feed oil to the bushing surface, ensuring consistent lubrication and extended service life.
- Micro-Polished Hardened Shafts – Precision finished shafts reduce friction and wear, improving overall valvetrain efficiency and durability.
- No Loose Internal Components – Unlike needle bearing setups, this design eliminates small internal parts that can come loose and cause catastrophic engine damage.

Great value
Very clean rocker arms, some looked brand new some looked used. Trunion kit was brand new and felt great. Going into a new build. This was as cheap as if I had done it myself. I highly recommend you pick this kit up to replace your factory rockers!
