ARP High Performance Series Cylinder Head Bolt Kits 134-3609

Our Summit Racing™ gear drives are great for you folks who want better timing and a choice of “noisy” or “quiet” operation. Their dual-idler design has CNC-machined components and they are easy to install. Each set comes with a pressed-in Torrington bearing or an SAE 660 bronze thrust washer (varies by application), as well as a cam gear that allows for timing adjustments in two-degree increments. These drives fit under your stock timing cover and come complete with instructions. Minor machining is required on models with the bronze thrust washer.
