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 and quicker reving. This kit includes a new under-drive crankshaft pulley, crankshaft bolt and ribbed belt.
The NEUSPEED crankshaft pulley is made from 7075 aluminum and hard anodized for durability. Unlike color anodizing which is mostly cosmetic, hard anodizing builds up a hardened layer over the base material to help prevent wear.
