Weight reduction is how we are able to increase horsepower. Each pound of weight removed from the crankshaft is worth approximately 2.7HP, and our stock diameter crank pulleys are at least 60% lighter than the OEM pulleys they replace, our undersize crank pulley could be up to 90% lighter than the OEM pulleys.
There are no adverse effects from using any of our pulley versions. Bolt them on and forget about them!
Works Engineering crank pulleys are precisioned CNC with the highest grade light weight forged aluminium. Our Pro Balancing series are black oxide coated and hardened for even more strength, you will never have to worry about unbalance or breakage due to material fatigue.
