7.25 DIAMETER FOR OVERDRIVE.
OTHER CUSTOM DRIVEN DIAMETERS UPON REQUEST
Capable of using compression springs with adjustable spring rate options. Any helix angle available upon request. We can even provide multiple helix angles to your desire. We currently have 35,38,40,42,45, and 42/40 degree helixes in stock.
This driven is also capable of external belt deflection adjustment while installed on the car, no more shims. The dual roller option creates a very consitant smooth up shift and backshift. The use of the helix body to support the movable sheave instead of towers keeps the whole assembly concentric and centered without twisting while under load.
