Serpentine Pulley Kit LS Engine

The Serpentine Pulley Kit LS Engine by Eddie Motorsports is designed for builders and enthusiasts looking to optimize accessory drive performance on LS-platform engines. This kit is ideal for street rods, restomods, and modern performance builds, addressing the critical aspect of efficient power transmission from the crankshaft to various accessories.

Engineered to OEM standards, this complete pulley assembly consolidates multiple pulleys—typically for the alternator, water pump, and idler pulleys—into a matched set that maintains precise belt geometry. This design minimizes vibration and reduces parasitic drag, ensuring consistent belt tension under varying engine loads, which is essential for both daily drivers and high-performance applications.

The Serpentine Pulley Kit is compatible with LS engine swaps and builds across all generations, from LS1 and LS3 to LT platforms. By reducing friction losses, this kit enhances horsepower and improves cooling system efficiency, making it a valuable upgrade for any LS engine enthusiast.
