Wiseco Pistons Top End Needle Bearing

Wiseco Top End Needle Bearings are precision needle cage bearings. They support the piston pin (wrist pin) at the small end of the connecting rod. They are also called wrist pin bearings, piston pin bearings, upper rod bearings, or top end bearings. Each one is built for a two-stroke or four-stroke top-end rebuild.

Key Features:

• Needle cage design: Needle rollers let the piston pin pivot smoothly with low friction at the connecting rod small end.
• Precision manufactured and inspected: Wiseco makes and checks each bearing for quality and consistent fit.
• Built to OEM-level specifications: Wiseco's distributor listings say these bearings are manufactured to the highest quality OEM specifications.
• Wide powersports coverage: The line has many bearing sizes. They are used in motorcycle, ATV, snowmobile, and personal watercraft engines.
• Good rebuild companion: Replacing the top end bearing along with the piston and rings helps restore smooth operation and reliability.

Wiseco is a well-known maker of pistons and engine components for powersports. A fresh top end bearing helps protect the piston pin and rod small end during a rebuild. Choose the child item that matches the bearing dimensions your engine requires.
