Computer designed and CNC machined to exacting tolerances and perfect balance, these pulleys are made from billet 6061-T6 by using an aerospace forging process, which creates pulleys that are 400% stronger than cast pulleys and 50% stronger than plain billet pulleys! For durability and safety, each pulley is heat treated to a T-6 condition which hardens and strengthens the pulley forging to prevent fatigue cracking. Pulleys are then double tempered the forging to improve overall toughness and to prevent warping under load.

Available in machined finish or a hand polished finish. We do not powder coat our pulleys nor recommend powdercoating of pulleys due to the inherent yellowing, cracking and chipping of this process.
