Complete +.25mm Engine Rebuild Kit for Kawasaki Ultra LX Jet Skis

After machining your cylinders for +.25mm oversize pistons, choosing the correct rebuild kit helps ensure everything goes back together the right way. This complete engine rebuild kit is designed for 2012-2020 Kawasaki Ultra LX Jet Ski models and includes the major components needed to restore engine performance while allowing you to reuse valves that remain within factory service limits.

The +.25mm designation applies to the piston kits only. By replacing the rotating assembly, bearings, timing components, and gaskets during one teardown, you can complete your rebuild more efficiently and reduce the likelihood of future engine disassembly.
