Kawasaki STX 160, STX-160X & STX-160LX Complete Bottom End Rebuild Kit

A complete lower-end rebuild is often the best path forward when inspection reveals wear beyond bearings alone. This rebuild kit is designed for 2020-2026 Kawasaki STX 160, STX-160X, and STX-160LX models, combining the major rotating assembly components with the supporting parts commonly replaced during a complete bottom-end overhaul.

Instead of sourcing each component individually, this kit helps simplify the rebuild by bringing together the essential parts needed to rebuild the lower end with confidence.

What This Kit Includes

• Crankshaft
• Complete Gasket Kit
• Oil Pump Chain
• Connecting Rods
• Cam Chain
• Crankshaft Ball Bearing
• Crankshaft Outer Bearings

When Should You Choose This Kit?

This rebuild kit is a smart choice when inspection shows the crankshaft or connecting rods should be replaced rather than reused.

• Crankshaft journals show excessive wear or damage.
• Connecting rods no longer meet service specifications.

• You’re performing a complete lower-end rebuild for long-term reliability.

Complete Your STX 160 Engine Rebuild

If your crankshaft and connecting rods remain within specification, the STX 160 complete bottom end refresh kit may provide the components you need.

Planning to rebuild the upper engine at the same time? Pair this kit with the STX 160 complete top end rebuild kit for a more complete engine overhaul.
