The TEAM BOSS Rapid Response driven clutch is equally impressive in its design and focus on quality, featuring machined sheaves that mount directly to the machined-matched driven shaft.
On the BOSS system, the movable sheave (the sheave that moves to allow the belt to move lower into the clutch) slides on the driven shaft, rather than on a separate steel post thats built into traditional driven clutches. The result: a 0. 25-lb. weight reduction and quicker acceleration.
The area of the driven shaft on which the clutch slides/moves is polished for improved performance and increased bearing life. The shaft itself is larger diameter than traditional shafts.
