Aluminum Rockers

Light Weight Shaft-Mount Roller Rocker Systems


T&D aluminum shaft-mount roller rockers offer strength, accuracy and performance in a light and optional ultra-lightweight aluminum rocker configuration. Designed primarily for race applications, T&D uses the finest 2024 aluminum for tensile and yield strength. T&D aluminum rockers far surpass industry standards for both strength and durability.

Steel Rockers

The Ultimate Rocker for Strength and Endurance


T&D steel shaft-mount rockers are engineered for applications with more extreme cylinder pressures and longer duration use. T&D uses a proprietary chrome-moly construction that minimizes flex and valve train distortion, ensuring reliable valve train performance. T&D steel rockers are also designed to minimize weight but with the highest strength on the market.
