Under-Drive & Lightweight Pulley Kits - GFB

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!

GFB Subaru BRZ Lightweight Pulley Kit (Sicon FR-S / GT86)  

Crank, Alternator & Powersteering Pulley's - Replacement Belts NOT Needed 

Part # 2016

 

This kit is supplied with 3 pulleys not just for looks - the combined saving of 4.9 lbs (2.2 kgs) is significantly more than what is achieved by replacing just the crank pulley alone.

The weight doesn’t tell the whole story either - even though the saving is a significant 77%, the actual rotating inertia reduction (inertia is what counts) is 83%
