COMP Cams Timing Set LS RHS Single 9Key

This is the COMP Cams 9-Keyway Single Chain Timing Set, part number 9672T9. It's built for GM LS engines, specifically those with a 3-bolt camshaft and either a 58X or 4-pole crankshaft reluctor wheel. This timing set is designed for raised cam blocks, such as the RHS race block, which has a .388" cam height. Getting the timing right is crucial for engine performance and longevity, and this set ensures a precise setup for these specific LS configurations.

The single chain design is well-built for durability and accurate timing signal transmission. The 9-keyway feature allows for multiple cam timing positions, giving you flexibility to dial in your engine's performance. This is particularly useful when working with modified LS engines where optimal cam timing might differ from stock. The inclusion of the necessary components for the 58X and 4-pole reluctor systems means it's ready for many popular LS engine builds and swaps.

When installing this timing set, pay close attention to the specific keyway position that achieves your desired cam timing. Referencing your engine build specifications or consulting with a performance engine builder can help you select the best position. This set is a solid option for anyone rebuilding or heavily modifying a GM LS engine that requires this specific timing configuration.
