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 Crank Pulley was designed and engineered in-house to access that lost power while providing an aesthetically pleasing appearance. Not to mention, our pulleys weighs in at a mere 13 ounces (375 grams) in comparison to the OEM crank pulley weight of 57 ounces (1589 grams). Even with a stock diameter, lightweight crank 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.
