Cosworth's Timing Belt Guide replaces the factory sheet metal timing belt guide to help reduce the possibility of the timing belt skipping a tooth during high rpm use.
The original sheet metal timing belt guide can flex from belt deflection when subjected to extreme RPMs causing the timing belt to skip one or more teeth on the crankshaft sprocket. The Cosworth Billet Timing Belt Guide was developed to control this problem and is machined from solid aluminum with a hard anodized finish. Includes mounting hardware.
