Hi Bob,

i am pretty sure that Tran X is the same as a Salisbury LSD and is still =
available through TR Enterprises here in the UK.

I do not know what car you are using (TR4 i think) so a new Tran X is =
probably ok. I have 2 Salisbury LSD units in 2 axles for my TR4.

However, if you are running a TR6 then I would recommend a Gripper LSD =
as they can handle the extra power and need a lot less maintenance than =
the Salisbury (I swapped out and sold both my Salisbury LSDs for 2 new =
Grippers for my TR6).

www.gripperlsd.com <http://www.gripperlsd.com/>

Of interest my TR4 produces 194 bhp at the flywheel and my TR6 produces =
252 bhp at the flywheel.

Hope that helps,

Keith
