Technical Support & Build Guidance

Before you choose your piston size, review our engine rebuild kit guide. It helps compare kit levels, piston sizing, and the parts each package includes.

For piston prep, ring placement, and final setup checks, the piston and ring installation guide is worth keeping on the bench.

If your build 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 +.50mm piston kits. If STD piston kits are the better fit, review the 2020-2026 Kawasaki Jet Ski STX-160/X/LX complete engine rebuild kit with STD piston kits.

For a smaller piston oversize, check the 2020-2026 Kawasaki Jet Ski STX-160/X/LX complete engine rebuild kit with +.25mm piston kits. If your repair only needs crankshaft, rods, +.50mm piston kits, bearings, chains, and gaskets, the 2020-2026 Kawasaki Jet Ski STX-160/X/LX engine rebuild kit with +.50mm piston kits may match the job better.
