Partno.: 2221GFB lightweight BRZ/86/FR-S alternator pulley direct replacement (part number 2221) is made from aircraft-grade 6061-T6 aluminium and is significantly lighter (and better looking!) than the factory pulley.
This is the same pulley as found in our complete 3-piece pulley kit for the BRZ/86/FR-S (part # 2016).
Our products are manufactured in Australia and the company is accredited to ISO 9001, this ensures our products meet stringent quality requirements at all stages of manufacture.
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 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!
