Vixen - stronger diff

[thunderbox1000]

Does anyone have details of the stronger Triumph diff ? Or photos of the comparison of the internals to help identify. CC have a useful reference list of all the Triumph casing numbers but it would be good to know which types are the beefed up ones.
Thanks

Is it possible to convert the Vixen over to the Salsbury diff like it is on the Tuscans ?
Would it not make sense shoot me if its a silly question

IF you're not too concerned about originality, there's probably several diffs that will fit - with a bit of bracketry and welding. The TR6/Triumph Saloon diff isn't that much larger for example, from the same period.

Also there's probably lots of other makes....BMW, Jap ones ?

The 'M' series cars had a rear subframe to adapt them for Spit/TR6/Salisbury diffs....

Welding, cutting and making something else fit is fine but as a bolt-on diff, the Triumph unit is OK on a Vixen S2, its just that some diffs have stronger innards, its a case of finding which ones.

they also say this about the diff

The GT6 differential in the Vixen is the weakest link in the chain. Kingston

Sportcars and John Kipping are the best suppliers of quality units. The former

will do a bog stock unit for engines with not more than 100 bhp at the

flywheel, an uprated unit for up to 200 bhp and a limited slip unit using

the torsion coupling system for more power and serious motor sport

applications. The Spitfire Mk. V unit apparently has the stronger crown

wheel compared with the GT6 unit and is available in a 3.63 as well

as the standard 3.89 ratio.



The u/js are the next weakest link and then (probably) then

quill shafts in the uprights although it is unlikely you will break these

with less than 250 bhp. Always ensure the propshaft is very well

balanced as otherwise this will ruin a diff and gearbox.

Avoid very heavy clutch starts and watch the u/js for knock. One component

with slack will wear the others more quickly.

Yep hes down under. It would be good if someone started a thread to update the old info, I have found several things that need correcting myself.
