Precise Timing Control for Serious Engine Builds

Speedmaster timing belt drive systems give engine builders precise, repeatable camshaft control for high-RPM street and race applications. Each system is engineered as a matched package, with robust billet or cast housings, hardened idler and tensioner assemblies, and high-strength belts designed to maintain accurate valve timing under boost, nitrous, and extended track use. Detailed attention to pulley geometry, bearing support, and sealing helps reduce harmonics and belt walk while protecting front-end components. These kits support degreeing and fine-tuning cam phasing so you can optimize cylinder pressure, drivability, and power output with confidence.
