Katech C5-R Timing Chain for GM LS Engines (1997–2019)
High-Strength Timing Chain for 4.8L, 5.3L, 5.7L, 6.0L, 6.2L & 7.0L LS Engines | Katech KAT-7636
The Katech C5-R Timing Chain (KAT-7636), formerly known as HME-G68V-2, is built to significantly higher tensile strength standards than factory LS timing chains—ensuring exceptional durability, accuracy, and long-term reliability. This is the exact timing chain used in Katech-built C5-R and C6-R championship-winning racing engines, making it one of the most proven and trusted upgrades available for GM Gen III, Gen IV, and Gen V LS platforms. Ideal for camshaft swaps, performance builds, and high-mileage engines, this chain installs using factory sprockets and offers unparalleled longevity. Authentic Katech chains feature the Katech logo stamped on the chain link—beware of imitations lacking this marking.
