This kit combines major bottom-end rotating components commonly replaced during engine rebuilds to help support smoother operation and dependable long-term performance.

Because the crankshaft and connecting rods handle constant load, RPM, and combustion force, replacing worn components during service helps protect the engine and support a stronger rebuild.

• Connecting Rods
• Connecting Rod Bearings

Fitment

• Kawasaki Jet Ski STX-15F 1500

Why Replace the Crankshaft & Connecting Rods?

The crankshaft and rods convert combustion into usable power and keep the rotating assembly operating correctly. Over time, wear can lead to vibration, excessive clearance, reduced performance, or internal damage.

Replacing these major components during service helps restore balance and supports long-term engine reliability.
