Speedmaster LS3/L92 Pedestal Mount 1.8 Ratio Aluminum Rocker Arms with Hardware PCE261.1254.03

The Speedmaster LS3/L92 Pedestal Mount 1.8 Ratio Aluminum Rocker Arms are precision-engineered components designed for LS engine cylinder head assemblies. These rocker arms feature a 1.8:1 mechanical advantage ratio and are constructed from aluminum for weight savings and durability. The pedestal mount design integrates seamlessly with LS3 and L92 platform engines, and the package includes all necessary mounting hardware for straightforward installation.

These rocker arms deliver improved valve actuation geometry and enhanced engine performance in naturally aspirated and supercharged LS applications. The aluminum construction keeps overall engine weight down while maintaining the rigidity needed for consistent valve timing across the RPM range. Built to OEM specifications for LS cylinder head compatibility, they're ideal for street machines, performance builds, and engine rebuilds where reliable valvetrain geometry is essential.
