PROX Crankshaft Seal 20x40x7mm (ref. 41.4-1188)
An essential wear part to maintain engine sealing on Cross machines, this PROX seal is designed to replace a worn or damaged crankshaft seal. Sold individually, it features standard dimensions of 20x40x7 mm for direct replacement of the original seal.
Designed for demanding riders and mechanics, this crankshaft seal is used during engine disassembly, crankshaft replacement, or to repair a localized oil leak on the crankshaft side. Compatible with many Cross models, it is particularly suitable for KAWASAKI KX85 (std and big wheels) and SUZUKI RM65 according to manufacturer references. Check the dimension 20x40x7 mm before ordering to ensure compatibility with your casing.
Easy to install with the appropriate tools, this PROX seal allows for reliable localized sealing between the casing and the crankshaft shaft — a discreet yet essential component to keep the engine clean and operational during enduro and cross outings.
