PROX Crankshaft Oil Seal 18x30x7 mm
UNIT — Replacement part designed for motocross bikes, engineered to ensure sealing between the crankshaft and the engine case. Compact and precise, this oil seal minimizes oil leaks and protects the internal components of the engine from impurities.
On the track as well as on trails, a faulty oil seal quickly leads to oil leaks and unwanted play on the crankshaft.
