Product Summary

Premium replacement rod bearings for '49-'53 Ford flathead engines
High quality aluminum bi-metal construction, Bi-metal withstands 662° F (350° C) compared to tri-metal 365° F (185° C). Affords greater protection against localized overheating due to misalignment, detonation, overloading, loss of coolant
Superior Embed-ability, material is much thicker than Babbitt overlays (.012" vs. .0008"). This provides greater macro-particle (> .0004" diameter) embed-ability. Macro particles are most responsible for scratching crank journals & tearing/weakening Babbitt overlays
Excellent conformability, minimum depth of .012" enables greater adjustment to bore or journal misalignment without causing bearing failure or journal damage
Tolerance Control is ± .0001" vs. the competitions' ± .00025" and available in standard, .010", .020" and .030" undersized to fit your needs
