It might be hard to imagine how reducing the mass of a pulley makes a car go faster, but accelerating a heavy factory pulley from say 3000-7000 RPM in a second or two saps a measurable amount of torque. GFB Lightweight Pulleys reduce inertia by up to 85...

These crankshaft spacers are specifically designed for use with Ford Racing's crank dampers to achieve proper belt alignment on earlier model 5.0L and 5.8L engines. They are precision-machined on CNC equipment for a perfect fit, have a 3 or 4-bolt pulley...
