Description
Go Fast Bits lightweight crank pulley kits are constructed from aircraft-grade 6061-T6 aluminum and offer faster acceleration through significant weight reduction on the crankshaft. The amazing effect is similar to a lighter flywheel, and the car feels more aggressive and willing to rev. Most of our kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses. It should be noted that our underdrive pulley kits do NOT adversely affect the operation of the accessories. If they did, we would not sell them!
