The Moose Racing Crankshaft Bearing and Seal Kit provides critical components for rebuilding internal engine rotation on the Kawasaki KFX80 and Suzuki LT80. This kit contains precision right and left crankshaft bearings supported by durable seals designed to handle demanding recreational use. Specialized materials, such as fluorocarbon lips on two-stroke applications, ensure reliable sealing performance and reduced friction during operation.
ENGINEERING & PERFORMANCE
Right and left crankshaft bearings are packaged together to guarantee balanced support for the main shaft inside the crankcase. Two-stroke engine kits utilize outer seals constructed with a fluorocarbon lip that actively reduces dry start friction when the engine is initially cranked. This specific sealing design helps protect moving parts from premature wear during the startup phase, while four-stroke kits deliver the precise bearing geometry required to restore stable compression mechanics.

WHY RIDERS CHOOSE THIS
Riders choose this kit because it supplies the exact bearing pair needed to restore smooth engine rotation and prevent catastrophic shaft damage. The fluorocarbon seal design specifically addresses common wear points by lowering friction during cold starts, which extends the service life of the crankjournal and main bores. By providing both crank bearings and model-specific seals in one package, this rebuild kit eliminates guesswork and ensures all critical rotating assembly components meet factory clearances for lasting reliability.
