Cloyes Timing Set 9-3145; True Roller Double Roller for 1985 to 2002 Chevy 4.3L, 5.0L, 5.7L

Our competitors may say they have a true roller but only Cloyes has the original. The Original True Roller remains the benchmark against which all others are measured. Cam sprockets are machined from premium ductile iron or induction hardened cast iron. The three keyway billet steel crank sprockets are induction hardened then oil-quenched using our in-house multi-stage heat treat process. Our Premium True Roller chain features superior strength with full roller action. Side plates are cut and shaved from high strength steel and heat-treated for maximum fatigue resistance. The .250 inch rollers are cold rolled and hardened to exacting standards increasing load and RPM capabilities. All Original True sets are hand-matched at our manufacturing facility qualifying center distance and run-out, ensuring you the best with every set
