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.

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.
