The Michigan Motorsports LS3 Rocker Arms with Roller Trunion Kit Installed are a must-have upgrade for any LS engine, whether it's a stock or heavily modified setup. These rocker arms are designed to replace the stock bearings, which have a tendency to fail, especially in aggressive head and cam combinations.

The kit includes 16 new LS3 series rocker arms, each equipped with a premium 8620 steel alloy trunion and caged roller bearings. This upgrade greatly reduces the risk of bearing failure experienced with the stock LS needle bearings, which can result in loose needles scattered throughout the engine.

The new design employs caged roller bearings, providing a more durable and reliable solution compared to the cageless, loose OEM needle bearings and powdered metal trunion. This not only enhances the overall durability of the rocker arm setup but also ensures smoother operation and prolonged service life.

The kit also includes 16 bolts for the LS3 style rocker arms, making the installation process straightforward and hassle-free. Whether you're building a high-performance LS engine or simply upgrading an existing one, the Michigan Motorsports LS3 Rocker Arms with Roller Trunion Kit Installed are an essential component to consider.

Upgrading to this rocker arm kit is highly recommended for any LS engine, as it provides a significant improvement in reliability and performance over the stock bearings. The caged roller bearings effectively prevent the common issue of bearing failure, which can lead to catastrophic engine damage. By investing in this upgrade, you can rest assured that your LS engine will deliver consistent and reliable power, even under the most demanding conditions.
