Description

Engine Rebuild Kit +.25mm for 2012-2020 Kawasaki Ultra LX Jet Skis

Once your cylinders have been machined for +.25mm oversize pistons, selecting the correct rebuild kit helps ensure the rest of the engine goes together with confidence. Designed for 2012-2020 Kawasaki Ultra LX Jet Ski models, this kit includes the wear components most commonly replaced during an engine rebuild while allowing you to reuse serviceable hard parts.

The +.25mm designation applies only to the piston kits. Instead of replacing components that still meet factory specifications, you can focus on renewing the bearings, timing components, and sealing surfaces that experience normal wear throughout the life of the engine.

What This Kit Includes

• Piston Kits +.25mm
• Complete Gasket Kit
• Oil Pump Chain
• Cam Chain
• Crankshaft Ball Bearing
• Crankshaft Outer Bearings
• Crankshaft Bearing Inner Bearings
• Crankshaft Main Bearing

Replace the Wear Components That Matter Most

If your inspection confirms the crankshaft, connecting rods, and valves are ready for continued service, this kit provides an efficient rebuild option. Replacing the common wear items during one teardown helps improve reliability while keeping your rebuild focused on the parts that need attention.

• Install +.25mm piston kits after verifying cylinder dimensions.
• Replace crankshaft bearings before final assembly.
• Renew the cam chain and oil pump chain during the rebuild.
• Install a new complete gasket kit for dependable sealing.
• Reuse serviceable crankshaft, connecting rods, and valves after inspection.
