- Clevite 77 Pontiac High-Performance Connecting Rod Bearings
These Tri-Metal 77 engine bearings combine the strength of a copper-lead alloy layer with steel backing and an electroplated babbitt metal. The steel backing provides strength and durability; the babbitt overlay provides the critical surface characteristics of slipperiness and conformability. This ideal design has properties not even found in many original equipment bearings. Clevite offers main bearings, rod bearings and cam bearings in this series.

H Series -
- Best to start with when unsure which bearing to choose
- Medium level of eccentricity and high crush
- Enlarged chamfers for greater crankshaft fillet clearance
- Made without flash plating for better seating
- Use with crankshafts that have oversized fillets
- Use with engines that run mid-high RPM range
- Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface
- Typically the greatest level of eccentricity
- Rods and mains have high crush for maximum retention
- Most are fully grooved to maximize oil flow to rod bearings
- Reduced overlay thickness to prevent overlay fatigue
- Use where extremely high RPMs cause severe rod bore close-in
- Use where higher eccentricity is desired to narrow bearing contact patterns
