Complete +.50mm Engine Rebuild Kit for Kawasaki Ultra LX Jet Skis

When your engine has been machined for +.50mm oversize pistons, selecting the correct rebuild kit is the next step toward a dependable repair. Designed for 2012-2020 Kawasaki Ultra LX Jet Ski models, this complete engine rebuild kit provides the major components needed to restore the engine without replacing reusable valve components.

The +.50mm designation applies to the piston kits only. By replacing the rotating assembly, bearings, timing components, and gaskets during one teardown, you can avoid piecing together individual parts and complete your rebuild more efficiently.
