§ 02 / About this part
What it is
The PROX CRANKSHAFT OIL SEALS KIT, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
These seals sit at the ends of the crankshaft within the lower end. They are critical for maintaining primary compression on two-strokes or keeping oil isolated on four-strokes. Worn crank seals lead to air leaks, erratic idling, or gearbox oil consumption. This kit provides the specific seals for both the ignition and drive sides of the crank. Replace these during any major bottom-end rebuild to ensure engine reliability. Proper seating in the cases is essential for a vacuum-tight fit. Check the crank journals for scoring before fitting the new seals to your bike.
