Mazda 12A & 13B Underdrive Alternator Pulley
Includes:
1x Underdrive Alternator Pulley - 043-006
Details:
- Lightweight alternator pulley made from aircraft-grade 6061-T6 aluminium for light weight, and black anodized 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 75mm.
- Suits early 12A and 13B rotaries through to series 5 RX-7 (vehicles with 15 mm alternator shaft).
- Please check our other listings for underdrive crank pulleys and Waterpump pulleys.
- Made in New Zealand.
