Your VW Golf/Jetta MK4 power steering pump, 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, power steering and alternator pulleys. The result is reduced parasitic drag on the engine and increased horsepower for your Volkswagen. This kit includes new under-drive pulleys for the crankshaft, 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.
