Key Features & Benefits
- Complete LS Timing Chain Set: Includes the key timing components needed for compatible 1997-2006 Gen 3 LS engines, including the IWIS timing chain, 3-bolt cam sprocket, and crank gear. This makes it a practical choice for camshaft swaps, timing service, and engine rebuilds.
- German-Made IWIS Timing Chain: Features an IWIS German-made performance timing chain for dependable strength and consistent timing control. IWIS chains are a popular upgrade for LS builders who want a quality chain during performance cam installations or high-mileage timing system refreshes.
- 3-Bolt 1x Cam Sprocket Design: Built for early LS 24x applications using a 3-bolt camshaft gear. The 3-bolt cam sprocket design is commonly used when installing many aftermarket LS camshafts and is a must-have when converting from single-bolt cam gear setups where applicable.
- Fits Popular 1997-2006 LS Engines: Designed for 4.8L, 5.3L, 5.7L, and 6.0L LS-based engines, including LS1, LS6, LQ4, LM7, and related Gen 3 LS applications. This coverage makes it a strong timing set for street builds, swaps, truck engines, and performance LS combinations.
- Ideal for Cam Swaps & Engine Rebuilds: A fresh timing chain set is a smart upgrade during LS camshaft changes, front cover service, engine refreshes, and full rebuilds. Replacing worn timing components helps support accurate valve timing, consistent performance, and long-term valvetrain reliability.
