LS Engine Timing Chain and Cam Upgrade Kit

The GM 3 Bolt 4 Pole timing chain gear is used when converting from a 1 bolt camshaft to a 3 bolt camshaft. It is a stock replacement lower timing chain gear that fits all LS engines except LS7 and LS9. These high-quality ARP cam bolts have increased preload clamping force to ensure positive timing gear register. Their increased material strength overcomes valvetrain harmonics and stress.

The kit includes the following components:

3 bolt cam sprocket (58X) - 12586481 Crank sprocket - 12556582 LS2 (Heavy duty) timing chain - 12646386 ARP cam bolts - 134-1003

Our LS Timing Chain Kit comes complete with everything needed for a quick and easy Timing Chain installation. The high-quality components in this kit ensure accurate and reliable timing, which is crucial for the optimal performance of LS engines.

The 3 bolt cam sprocket is designed to replace the original 1 bolt camshaft, providing a more secure and stable connection between the camshaft and the timing chain. This increased stability helps to minimize timing variation and ensures consistent valve timing throughout the engine's operation.

The crank sprocket is a direct replacement for the original part, ensuring a perfect fit and compatibility with the rest of the timing system. The LS2 (Heavy duty) timing chain is a high-quality component that is designed to withstand the demanding conditions of LS engines, providing reliable and long-lasting performance.

The ARP cam bolts are a critical component in the timing chain system, as they secure the cam sprocket to the camshaft. These bolts are made from high-strength materials and feature an increased preload clamping force, which helps to prevent the cam sprocket from slipping or shifting during engine operation. This ensures that the timing remains accurate and consistent, even under high-stress conditions.

Overall, the GM 3 Bolt 4 Pole timing chain gear and the accompanying components in this LS Timing Chain Kit provide a comprehensive solution for upgrading or replacing the timing chain system in LS engines. The high-quality parts and precise engineering ensure a smooth and reliable timing chain installation, which is essential for achieving optimal engine performance and longevity.
