Your car's alternator and A/C are powered by a belt connected back to the crankshaft pulley. Spinning these pulleys draw precious horsepower from your engine. By replacing your crankshaft pulley with this underdrive pulley, parasitic drag is reduced and horsepower is freed up. This kit includes a new under-drive crankshaft pulley and a shorter belt.
Pulley is made from 6061 T6 aluminum and anodized for durability.
5 - 7 Horsepower gain.
