Crankshaft seal kits

Crankshaft seal kits include the essential oil seals installed at each end of the crankshaft to prevent engine oil leaks and contamination. These seals are critical for maintaining oil pressure, crankcase vacuum, and overall engine reliability. At Xpert Moto Gear, our kits feature premium rubber or Viton® seals with precision-fit lips and spring-loaded sealing rings. Xpert Shop seal kits ensure long-term durability, excellent heat and chemical resistance, and maximum engine protection, ideal for rebuilds or preventive maintenance.

Each Xpert Moto Gear listing provides model-specific fitment, engine type, and seal dimensions to ensure proper compatibility with OEM crankshaft designs. Whether you're rebuilding a motocross bike or servicing a street engine, we have the exact seal kit you need.

Installing a crankshaft seal kit from Xpert Moto Shop typically involves removing engine side covers, carefully extracting old seals using a puller or pick, and pressing the new seals into place with a seal driver. It's important to install the seals evenly, lubricate the inner lip with engine oil, and confirm correct orientation. Xpert Moto Gear kits include instructions or reference guidance, and we recommend professional installation for precision-critical engines.
