Technical Support & Build Guidance

Before you choose a piston size, use our engine rebuild kit guide. It can help you compare STD, +.25mm, and +.50mm piston kit options.

For piston prep and ring setup, keep the piston and ring installation guide on hand. It is a useful bench reference before final assembly.

If your build needs a standard-size piston kit, compare this option with the 2020-2026 Kawasaki Jet Ski STX-160/X/LX master kit with STD piston kits. If +.25mm piston kits are the better match, review the 2020-2026 Kawasaki Jet Ski STX-160/X/LX master kit with +.25mm piston kits.

If you need crankshaft, rods, +.50mm piston kits, bearings, chains, and gaskets without intake and exhaust valves, check the 2020-2026 Kawasaki Jet Ski STX-160/X/LX complete engine rebuild kit with +.50mm piston kits.
