Clutch Springs are an important part of the consistency of your racecar. The Driver Springs set your stall speed, which is the RPM at which your clutch will engage. The weaker the stall spring the lower your idle speed will have to be. At Huddleston Performance we tend to run a Purple stall spring in our 8.90 and slower combinations, and a Green stall spring in our 7.90 and quicker applications.

The Driven Springs control how quickly your Driven unit is allowed to open. The stiffer the spring you run, the slower the Driven unit can open which slows down the overall process of the clutch. You can change the shift rate of the Driven unit by changing springs or tightening the spring through the holes in your helix. The Red Driven Spring is the stiffest Driven Spring offered, with the Yellow being a more traditional choice. We like to use the Red Driven Spring with our new Multi-Angle Helixes for 7.90 and quicker cars, and the Yellow Driven Spring with a Multi-Angle Helix on 8.90 and slower combination.
