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. NEUSPEED's powertrain engineer, using sophisticated CAD software, performed a mass properties analysis of the crank pulley. The result is reduced parasitic drag on the engine, increased horsepower, better response, quicker revving, and better MPG. This kit includes a new under-drive crankshaft pulley and a shorter belt.
The NEUSPEED crankshaft pulley is made from 6061-T6 aluminum and black hard anodized for durability.
