WOSSNER - 8923DB - Piston Kit - 77.97 mm - Gas Gas | Husqvarna | KTM

Engine rebuilds are only as good as the parts that go back in, and when it comes to the piston — the component under more sustained thermal and mechanical stress than anything else in the top end — there is no room for compromise. The WOSSNER 8923DB is a precision-engineered piston kit for 77.97 mm / Gas Gas | Husqvarna | KTM engines, built to hold dimensional tolerances across thousands of heat cycles. Enhanced piston pin oiling slots, radial boss machining, and annular grooves for improved wrist pin lubrication, giving you the kind of fit-from-day-one accuracy that prevents premature wear on the cylinder wall, wrist pin, and rings. Lightweight piston with a tight piston wall clearance for a quieter running engine. Bore Size: 78.01 mm. Whether you are overboring for more displacement or simply replacing what age and hours have worn out, the 8923DB gives you a forged foundation you can trust.
