CB663FXND Clevite 77 F Series Rod Bearings - SB Chevy 350 & LS & LS2 - STD Size

With the higher demands placed on today's engine bearings, MAHLE introduces the F-series engine bearing. The F-series bearing is the new standard for reliability with the highes load of carrying and thrust load ability in the industry; accomplished by using the latest technology in the materials and designs

The F-series bearing is a TriMetal lead-tin-indium-alumina electroplated overlay applied over Mahle's cast bronze lead substrate for maximum performance and reliability. The added ramp and pad thrust face creates increased oil pressure to the thrust wear surface which increases lubrication and bearing cooling; resulting in an ability to withstand a higher thrust load than conventional flath thrust surfaces.
