Kawasaki Ultra LX Jet Ski +.25mm Master Engine Rebuild Kit

After cylinder measurements confirm the need for +.25mm oversize pistons, it’s the perfect time to complete a full engine rebuild. This master engine rebuild kit fits 2012-2020 Kawasaki Ultra LX Jet Ski models and combines the major components commonly replaced during a complete overhaul into one convenient kit.

The +.25mm designation applies to the piston kits only. Instead of ordering individual parts from multiple suppliers, you can complete your rebuild with a coordinated collection of components designed to work together. As a result, you’ll spend less time sourcing parts and more time getting your engine back on the water.

Why Builders Choose This Kit

Once an engine is apart for machining, replacing the primary wear components during the same teardown helps protect your investment and minimizes the need for future engine disassembly. This master kit provides the major parts needed to complete the rebuild with confidence.

• Install +.25mm piston kits after cylinder machining confirms the correct bore size.
• Replace the crankshaft and connecting rods during one engine rebuild.
• Renew the cylinder head with new intake and exhaust valves.
• Replace timing components before final assembly.
• Complete the rebuild with new bearings and sealing components.
