Sealed Power Main Bearing Sets

4.44 out of 5 stars 97 Customer Reviews

Today's engines operate under very demanding conditions. When these Sealed Power main bearing sets are used in performance applications, all components are pushed to their limits—and many must be changed to meet these special demands. Federal Mogul, a longtime supplier to both OEM and the aftermarket, has responded to this challenge with its tri-metal, copper-lead, high performance main bearing sets. They're tested in the lab and proven on the track. The bearings are available for various crankshaft undersizes, for direct replacement or performance usage on a wide range of specific applications.
