A top end rebuild without fresh gaskets is a rebuild waiting to fail. The ProX 35.6118 supplies every gasket needed for the top end of the KTM 85 SX and Husqvarna TC 85 from 2018 to 2026 in a single kit. Both bikes run the same engine platform and the same sealing requirements, covered by one part number.
The kit includes the cylinder head gasket, cylinder base gasket, exhaust pipe gasket, and intake gasket. All gaskets are CNC precision cut to OEM specification dimensions. The materials are selected to handle the operating temperatures, pressures, and fuel contact of a high-revving 2-stroke engine.
ProX manufactures to OEM tolerances, which means correct thickness, correct bore cutout dimensions, and correct material hardness for each sealing surface. Generic gaskets cut slightly wrong cause compression leaks that are difficult to diagnose and expensive to fix.
Replace every gasket in this kit during a top end rebuild. Reusing any gasket from the previous build introduces a known weak point into an otherwise fresh engine.
