Light Weight Aluminium Under Drive Crank Pulley
This is a custom CNC machined crank pulley. It is made of aircraft grade aluminium and weighs just less than 1kg. Stock pulley weighs 2.5kgs. and robs h.p. from the engine to spin it.
Just like a light flywheel, throttle response will be greatly improved!Installs in minutes. Requires replacement of alternator and power steering/air conditioning belts.
Our pulley set provides most of the power gains through weight loss (80-85%). The remaining part of the gains from these pulleys comes from under driving of all the accessories (15-20%).Our under drive pulley sets are available in polished finish only. This unit requires the use of replacement belts (Shorter) which are supplied in the kit. We are adding new models to our range as quickly as possible.
Kits are supplied with replacement belts.
