Durable crankshaft with rod and plain bearing for CF450
✔️ Crankshaft connects piston to engine block with plain bearing

This heavy duty ATV crankshaft kit replaces worn engine internals in CF450 quads. You will bolt it directly into your cylinder case to restore clean power delivery after trail wear. The assembly brings back steady RPM control through rough washboard sections.

✅ Direct straight bolt mounting for quick shop floor installs ✅ Complete connecting rod and plain bearing included for immediate swap ✅ Built for CF450 and 520 ATV platforms requiring straight pins ✅ Handles high compression loads for longer bottom end life

💡 How do you keep engine timing reliable after a bottom end rebuild?
Heavy grade steel keeps performance handy on steep mud climbs
Plain bearing journals minimize drag for quicker throttle recovery
Straight bolt pattern makes swaps handy when trailside parts fail
Fits right into your 191Q block for fast reloads
