Put a stop to gear box oil leaks by installing this new O.E.M. quality seal. I personally like to use this seal rather than our other “cheaper” high gear seal because this seal is double-lipped to prevent oil leaks.

Seal also has a metal backing just like the original seals that where fitted to Triumph and BSA models back in the day – easy to install.

Measures 1 9/16″ x 2 1/2″ x 5/16″ suited for twins both 500 & 650 (Bonneville, T120, T110, 6T, Thunderbird, Tiger, TR6, Etc) from 1947-1972 with the 4-speed gear box. Also fits all BSA A50 & A65 Unit Twins from 1962-1972. Please refer to your parts catalog for proper fitment.
