Bearings

These WPC-treated bearings are the best we have seen! WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are original equipment KS bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.

Often called main bearings, crankshaft bearing shells sit between the rotating assembly and the engine block. They allow the crankshaft to rotate freely, but are prone to wear from deterioration and lack of lubrication.

This complete set consists of nine bearings, enough to fill each journal.

If you're overhauling your M10, choose Hella crankshaft-bearing shells for a lasting solution.
