New Old Stock! Bought it for my old GTI, never got to install it when I sold the car, then we moved so it has been sitting in a box waiting for a new home. Crank Pulley Replacement Kit #62.10.92

From their website;

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 revving. 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 and wear, plus a NEUSPEED exclusive: stainless steel ring that has been ground finished and heat-treated to prevent pulley wear against oil seal.
