Reducing the amount of effort it takes your engine to spin the accessories results in more power being sent to the wheels. The ECS Tuning Lightweight Pulley set was designed and engineered in-house to access that lost power while providing an aesthetically pleasing appearance. Even with a stock diameter, lightweight pulleys reduce the rotational mass and moment of inertia to provide improved throttle response and there's no need to change from your standard length accessory belt.
ECS' lightweight pulleys are machined from billet aluminum, for reduction in weight and to maintain strength, and then anodized with a black finish to resist harsh weather and road salt to provide years of reliable service. A simple bolt-on replacement that will have your engine spooling faster in no time.
