"Bump-Out" Access Cover for TR Gearbox Cover


P1228 "Bump-Out" Access Cover for TR Gearbox Cover: $29.95


This is the long-unavailable cover which Triumph made and supplied on cars with the angled speedo-drive or overdrive. It provides necessary clearance as well as access for serviceability.

We have now made a dedicated mold and are producing these in ABS plastic. The parts are very consistent, as well as lighter and easier to work with.

We supply these complete with adhesive-backed gasket, and screws.

See photos for installation.


The bump-outs arrived on Thursday and I have already installed one! Fits perfectly and great product! Thank you!
