Description

Cloyes Race Billet True Roller timing sets provide race-ready performance! These sets feature sprockets machined from premium billet steel on state-of-the-art CNC equipment to ensure the highest quality and consistency. The sprockets are induction-hardened and oil-quenched by Cloyes' in-house, multi-stage heat treat process. Sets include a Cloyes Premium True Roller chain—which features full roller action and superior strength. Side plates are cut and shaved from high-strength steel and are heat-treated for maximum fatigue resistance. Their .250 in. rollers are cold-rolled and hardened to exacting standards, increasing load and rpm capabilities. Cloyes Race Billet True Roller Speed Sets are offered with a choice of 3-or 9-keyway crank sprockets, providing multiple valve timing settings. These sets are hand-matched to qualify center distance and runout, ensuring the best performance with every set!
