Kawasaki STX 160 Jet Ski Crankshaft and Rod Kit

The crankshaft and connecting rods are the foundation of every engine rebuild. If inspection reveals excessive journal wear, damaged rod bearings, or a failed rotating assembly, replacing these components together can help restore reliability and simplify the rebuild process. This kit fits 2020-2026 Kawasaki STX 160 Jet Ski models.

Rather than sourcing individual components, this kit combines the primary rotating assembly parts commonly replaced during a complete lower-end rebuild. As a result, you can spend more time rebuilding and less time tracking down parts.

What This Kit Includes

• Crankshaft
• Connecting Rods
• Connecting Rod Bearings

When Should You Replace the Rotating Assembly?

Inspect the crankshaft and connecting rods during every lower-end teardown. If any major components fall outside factory specifications, replacing them before reassembly helps protect the rest of the engine.

• Crankshaft journals show scoring or excessive wear.
• Connecting rods fail inspection.
• Rod bearings show damage or excessive clearance.
• A bearing failure has damaged the rotating assembly.
• You’re completing a full lower-end rebuild for long-term reliability.

Complete Your STX 160 Bottom-End Rebuild

If you need the supporting bearings, chains, and gasket components, compare the STX 160 complete bottom end rebuild kit.

If your crankshaft remains serviceable, but the supporting wear items need replacement, review the STX 160 complete bottom end refresh kit.

Also, replace the lower-end bearings during assembly with the STX 160 crank bearing kit.
