ECS Lightweight Underdrive Crank Pulley for VW 2.5L -
Lightweight aluminum crankshaft pulleys from ECS Tuning punch above their weight. Precision machined from anodized billet aluminum, our great looking upgrades bolt on easily in place of your portly stock pulley.
Choose from stock diameter or underdrive. Either pulley reduces rotational mass for faster throttle response. The underdrive option reduces parasitic horsepower loss.
The bare stock pulley works with your standard length accessory belt; the underdrive kit comes with a shorter Bando belt.
Buy them for function. Because they look great. Or both!
