§ 02 / About this part
What it is
The PROX Clutch Spring Kit Steel KTM SX450/520/525 + EXC, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
These springs provide the clamping force required to keep your friction pack engaged. Heat cycles cause standard parts to lose tension over time. High-stress racing accelerates this fatigue. This results in slipping under load. It also causes accelerated wear on your plates. This kit is specific to your model fitment. It replaces tired OEM components to restore lever feel and power transfer. Always check your plate stack height during the rebuild. Inspect the basket for notches at the same time. Use a cross-pattern when tightening the pressure plate bolts to ensure even seating.
