Propshaft & Fittings
During the life of the Spitfire, Triumph introduced 3 different types of propshaft:-
'Sliding Spline'
'Strap type'
'Pot Joint' (cv joint).
Our replacement propshafts are the 'Sliding Spline' type or 'CV Joint' type, depending on availability,
We can supply replacement universal joints, but NOT CV joints. We are unable to supply 'Strap Type' for the forseeable future.

Differential Assembly
Differential Re-Builds
Differentials require specialist knowledge and tools to dismantle & rebuild, and are normally beyond the ability of the DIY enthusiast, we strongly recommend the fitting of a reconditioned exchange unit.
However, if you do intend to recondition your own unit, please contact us with the parts you require, and we may be able to supply them from stock.
