PROX Clutch Spring Kit for KTM EXC, SX 250, 300, 360, 380, HUSQVARNA WR 250, 300 and HUSABERG TE 250, 300 1996-2013

The PROX 17.CS63011 clutch spring kit is designed for KTM EXC 250, EXC 300, EXC 360, EXC 380, SX 250, SX 360, SX 380, HUSQVARNA WR 250, WR 300 and HUSABERG TE 250, TE 300 from 1996 to 2013. The clutch springs clamp the plate pack together. With heat and hours of use, they lose length and strength: the clutch slips, even with plates in good condition.

Specifications

• Brand: PROX
• Manufacturer part number: 17.CS63011
• Engine: 2-stroke

When to replace it?

Fitting tips

1. Replace all the springs together for even pressure.
2. Tighten the bolts gradually, in a criss-cross pattern, to the manufacturer's torque.
3. Take the opportunity to check the friction plates and the steel plates.
4. Close up with a new clutch cover gasket.

Frequently asked questions

Will the lever be heavier?
Springs to OEM spec restore the original lever effort. Heavy-duty springs, on the other hand, make the lever slightly stiffer.
