Technical Support & Build Guidance

Before you pick a piston size, use our engine rebuild kit guide. It helps compare STD, +.25mm, and +.50mm piston kit options, along with the parts included at each kit level.

For piston prep and ring install checks, review the piston and ring installation guide. It is a good bench reference before final assembly.

If your rebuild also needs intake and exhaust valves, compare this kit with the 2020-2026 Kawasaki Jet Ski STX-160/X/LX master engine rebuild kit with +.25mm piston kits. If your build needs STD piston kits instead, review the 2020-2026 Kawasaki Jet Ski STX-160/X/LX complete engine rebuild kit with STD piston kits.

For the next oversize option, look at the 2020-2026 Kawasaki Jet Ski STX-160/X/LX complete engine rebuild kit with +.50mm piston kits.
