Harley-Davidson Adjustable 24-Tooth Cam Chain Pinion Sprocket | Twin Cam & Milwaukee-Eight M8

Fine-tune your Harley-Davidson engine's performance with this Premium Adjustable 24-Tooth Camshaft Drive Pinion Sprocket, engineered to provide precise camshaft timing adjustments for improved power delivery. Designed for Harley-Davidson Twin Cam and Milwaukee-Eight (M8) engines, this adjustable sprocket allows up to ±4 degrees of cam timing adjustment, giving engine builders and performance enthusiasts greater control over engine characteristics.

CNC-machined from high-strength, bearing-quality billet steel, this sprocket is built to withstand the demands of aggressive camshaft profiles and high-performance valvetrains. Hardened tooth profiles promote smooth chain engagement, minimize wear, and provide long-lasting durability under demanding operating conditions.

Adjusting camshaft timing allows engine builders to fine-tune the powerband by advancing or retarding cam timing to influence torque delivery and horsepower characteristics. Whether you're dialing in a performance camshaft or optimizing a custom engine combination, this adjustable pinion sprocket provides the precision and flexibility needed to get the most out of your build.
