BBC Billet Roller Timing Set w/Shim

The BBC Billet Roller Timing Set w/Shim is designed for big-block Chevrolet engine builders who require precise cam timing control. This roller timing set replaces outdated gear-driven systems, providing the accuracy and durability essential for street performance, racing, and rebuilt engines where repeatability is crucial.

Featuring roller bearings instead of friction-dependent gear teeth, this timing set minimizes wear and heat generation during operation. The included shim allows for fine-tuning of timing advancement or retard relative to the camshaft's installed position, which is vital for optimizing ignition timing and valve overlap for peak performance.

Engine builders upgrading big-block Chevrolet engines appreciate the reduced parasitic drag and increased service life of roller timing sets compared to traditional gear sets. Installation requires standard timing cover removal and basic engine building knowledge, ensuring that mechanics can achieve reliable performance in various applications.
