BSA A50 / A65 High Gear Replacement Bushings By CBS (1 PAIR) - 68-3178 - 1962-72

  • Sale
  • Regular price $ 39.95

A worn high gear bushing can contribute to a few critical issues such as gear “slop” as well as oil seal failure - today we are offering a new set of bronze replacement high gear bushings for $39.95 (1 pair)

Our bushings were developed right here in the CBS workshop to replace the original “split” metal-backed bushings

What makes our USA made high gear bushings superior to the original style bushings is the fact that you can size your high gear (hone) to accommodate mainshafts that have wear 

Not to forget, bronze has great wear properties to prevent premature mainshaft wear - the 2-piece design and gap allows oil to properly lubricate both the gear and main shaft 

Fits all BSA Unit Twins A50 & A65 (Lightning, Thunderbolt, Spitfire, Firebird, Royal Star, Hornet, Etc) from 1962-1972. Please refer to your parts catalog for proper fitment.
