- Lightweight crank pulley made from aircraft-grade 6061-T6 aluminium for light weight, and black anodised for great looks.
- Offers faster acceleration through significant reduction of mass having to be accelerated by the crankshaft. The effect is similar to a lighter flywheel, and the car feels more lively and willing to rev.
- Pulley outside diameter is 88mm.
- Suits early 12A and 13B rotaries through to series 5 RX-7.
- Please check our other listings for underdrive alternator pulleys and waterpump pulleys.
