Clevite F-Series LS Rod Bearings

Clevite F-Series LS rod bearings are engine connecting rod bearings for GM LS-pattern V8 engines. Clevite is part of MAHLE. Also called con rod bearings or big-end bearings, they support the connecting rod on the crankshaft journal and keep a protective oil film between the two. They are offered in a range of undersize and oil clearance options so builders and rebuilders can match the bearing to the crankshaft and clearance they need.

Key Features:

• TriMetal construction: The overlay is a lead-tin-indium-alumina electroplated layer applied over MAHLE's cast bronze lead substrate.
• Greater load capacity: MAHLE testing showed a 126% increase in load carrying capacity before seizure compared with conventional copper/tin/lead overlay bearings.
• Fatigue and wear resistance: The overlay offers increased fatigue strength and wear resistance.
• Seizure resistance: Seizure resistance is higher than a coated bearing, with no additional thickness.
• Precision-manufactured: Built for the demands of high-performance street, strip and rebuild applications.

F-Series bearings use modern materials and design for durability under heavy loads. They suit engine rebuilds and performance builds where bearing reliability matters. Always measure crankshaft journals and set bearing clearances according to the engine builder's specifications before assembly.
