Your Audi's alternator, power steering 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 the 2009-UP Audi A4/A5/Q5 2.0 TFSI 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.
