Clevite F-Series LS Main Bearing Set Undersize

The Clevite F-Series LS main bearing set is an engine crankshaft main bearing designed for rebuilds and performance builds. It is made for use with crankshafts that have been ground undersize. Main bearings support the crankshaft and keep a film of oil between the bearing and journal surfaces. That film helps the engine run smoothly and last longer.

Key Features:

• TriMetal construction: A lead-tin-indium-alumina electroplated overlay is applied over MAHLE's cast bronze lead substrate.
• Higher load capacity: MAHLE testing shows a 126% increase in load carrying capacity before seizure compared with conventional copper/tin/lead overlay bearings.
• Fatigue and wear resistance: The overlay is made for greater fatigue strength and wear resistance.
• Seizure resistance: Seizure resistance is higher than a coated bearing, with no added bearing thickness.
• Undersize options: The line is offered in undersize versions, so you can match the bearing to a machined crankshaft.
• Trusted brand: Clevite is a MAHLE engine bearing brand, known for its Clevite 77 bearings.
