Neuspeed 62.02.50 Power Pulley Kit Audi A4 2005-2007

Your car’s power steering pump and alternator are powered by a belt connected back to the crankshaft pulley. Spinning these pulleys draws precious horsepower from your engine. NEUSPEED’s powertrain engineer, using sophisticated CAD software, performed a mass properties analysis of the crank, power steering and alternator pullies. The result is reduced parasitic drag on the engine and increased horsepower. This kit includes new pulleys for the crank, alternator, and power steering pump. NEUSPEED Power Pulleys are made from 6061 T6 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 prevent wear.
