COMP Cams Timing Set LS RHS Double 3Key

If you're building a performance LS engine, getting the camshaft timing dialed in is critical. This COMP Cams Hi-Techâ„¢ Roller Race Timing Set is built for those demanding applications, especially when you're working with a raised cam block like the RHS race block. It ensures your camshaft and crankshaft are perfectly synchronized, which is key for making power and keeping the engine running smoothly under stress.

This set uses a strong, induction-hardened billet steel crank sprocket paired with a cast iron camshaft gear. The double roller chain is pre-stretched and heat-treated, designed to handle the heavy loads found in racing. It's also dynamically balanced and checked for run-out, so you know it's going to be accurate. The 3-keyway design on the crank sprocket gives you flexibility in setting your cam timing, which is a big help when tuning for optimal performance.

This timing set is a solid option for both street performance builds and dedicated race engines. It's designed specifically for GM LS engines using the 3-bolt cam, 24X reluctor, and 1-pole reluctor configuration.
