This BBK pulley kit is made from quality aluminum alloy and is designed as a direct bolt-on replacement for the current pulleys, while also still retaining full cooling and charging characteristics. This hand polished aluminum pulley kit part provides an average of 8-15 added HP to your already high performing Firebird. The kit includes a waterpump pulley, alternator pulley, and a crankshaft pulley. A traditional mod is to underdrive the engine water pump. This effectively reduces the amount of HP consumed by the water pump and allows more power to accelerate your classic car. By making this addition, your car should experience much more crankshaft and wheel HP. The alternator pulley is responsible for transferring mechanical power from an engine crankshaft to the alternator via a belt. If you're a serious car enthusiasts wanting the most out of your mod, crank pulleys are a crucial part of your overhaul. The crankshaft is a critical component in your vehicles power distribution. Also called a harmonic balance wheel, this part connects to the crank shaft and drives the cars wheels by transmitting torque through the pulley system to other important elements of your Firebird. When you're in the mood to mod your 1988, 1989, 1990, 1991, and 1992 Firebird, invest in a BBK aluminum pulley kit.
