20 Best Ls Rocker Trunion Upgrade (2023 Updated)

The ls rocker trunion upgrade is a performance mod that replaces the stock rocker arms and trunnions in an ls engine with aftermarket pieces that are designed to withstand higher loads and offer increased durability.

The upgrade is popular among those who track their cars or participate in other forms of motorsport where the engine is subject to higher stresses. The ls rocker trunion upgrade can also provide a small increase in power due to the improved flow of oil to the rocker arms.
