Speedway Motors has all the parts you need to rebuild your Flathead Ford V8, including these high quality aluminum bi-metal rod bearings. Precision built to the high standards demanded by today's rodders and restorers, these insert-style bearings are available in standard size, .010", .020", or .030" undersize.

  •  Tolerance Control: ± .0001" vs. the competitions' ± .00025"
  • Superior Embedability: Material is much thicker than Babbitt overlays (.012" vs. .0008"). This provides greater macro-particle (> .0004" diameter) embedability. Macro particles are most responsible for scratching  crank journals & tearing/weakening babbitt overlays.
  • Temperature Threshold: 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, etc.
  • Conformability: Minimum depth of .012" enables greater adjustment to bore or journal misalignment without causing bearing failure or journal damage.


Some parts are not legal for use in California or other states with similar laws/regulations
