Specs & Features
- 3-piece underdrive pulley kit (Crank, alternator & power steering pulleys & belts.)
- Improved throttle response and acceleration through significant reduction of rotating mass
- Engine feels more free-revving
- Under-driven kits offer more power through reduction of parasitic losses from the accessories with NO adverse affects on their operation
GFB lightweight pulley kits are made from aircraft-grade 6061-T6 aluminium and offer faster acceleration through significant weight reduction on the crankshaft. The effect is similar to a lighter flywheel, and the car feels more lively and willing to rev.
Most of their kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses.
