Billet True Roller Timing Set - BBM 3-Bolt

The Billet True Roller Timing Set - BBM 3-Bolt by CLOYES is engineered for builders and engine rebuilders who demand precision valve timing control and durability. This timing set is designed for small-block applications running the traditional 3-bolt camshaft gear configuration, making it ideal for classic hot rods, street engines, and performance rebuilds where reliable synchronization between crankshaft and camshaft is critical. Whether you're assembling a fresh long-block or upgrading an existing platform, this roller timing set provides the mechanical accuracy necessary to maintain proper combustion events across the RPM range.

Billet construction delivers superior strength compared to cast alternatives, resisting wear and distortion under sustained high-RPM operation and mechanical stress. The true roller design reduces friction between the timing chain and sprockets, minimizing power loss and extending chain life—a tangible benefit in engines that see frequent track duty or modified power outputs. CLOYES' engineering ensures tight tolerances on both the crankshaft and camshaft sprockets, preserving valve timing accuracy and preventing the drift that can compromise performance tuning and fuel mapping. The 3-bolt attachment pattern is the industry standard for small-block platforms, ensuring straightforward installation during engine assembly without requiring custom machining or adapter plates.

This timing set is best suited for engine builders, mechanics, and enthusiasts performing complete engine overhauls or serious performance modifications. Installation requires proper timing chain tensioning and verification against your engine's specific timing degree wheel or dial indicator to confirm valve event placement. Verify compatibility with your camshaft and crankshaft before ordering—3-bolt configurations are common across many American small-block families, but confirmation prevents costly assembly errors.
