Salisbury locker options?

So far as I can tell, options are limited for the Salisbury (300tdi 110 rear) axel?

I don't think Ashcroft do one, so -

ARB
Raptor 4x4
(Both air)
or
Detroit trutrac
(LSD)

Is it really just those three options, or am I missing something?

Thank you.

maxi drive were the best imo but not sure if still available

Thank you.

Yep, i think maxi drive are long gone.

Im also trying to work out the detroit options -

Seems to be one that people call "no slip" - https://www.ashcroft-transmissions.co.uk/locking-differentials/salisbury-locker.html (eaton)
And the trutrac - https://www.ashcroft-transmissions.co.uk/limited-slip-differentials/detroit-truetrac.html (that one says tractek but i think thats just a subsidary of eaton)

Seems neither have external control, ie LSD, but the former (older) one will lock with a wheel off the ground, whilst the latter needs brake modulation to get it to lock up?

I dont know if the trutrac is smoother on the road or somthing, so thats why its been developed. Hard to tell.

Trutrac is limited slip differential whereas Detroit is permanently locked, then auto unlocking on corners which have a lot of grip(road)
Detroit isn’t recommend for wheelbase shorter than 130” although I had one in my Salisbury 110 rear, also had Ashcroft lsd in front axle. Worked brilliantly off-road but on road be prepared for lots of clanking as the Detroit locks back up after a road corner. Best option is swap rear axle for one with a Land Rover diff then have switchable locking differential fitted

Swapping to a 110 td5 rear axel with an ashcroft switchable would be possible, but damn near everyone says that the Salisbury is a superior unit in other respects?

ARB make a switchable for the Salisbury, but I read so many stories of people blowing out the oil with the compressor...

The second one, the one you have not fitted, is, I think, the one that will supply drive even with a wheel off the ground. The no-slip one.


Is there anything "bad" about the td5 axels? I mean is there much of a disadvantage in just fitting one of those?

the later 110 td5 short nose p38 diff,good axle stronger than std rover diff but salisbury is by far the strongest just by size of cwp and bearings apart from casing,depends on requirements

110 is used for -

Carrying stuff on road (up to half a tonne fairly often, somtimes more)
Towing
Some motorway driving (without much weight)

This is the common stuff.

Also, but less frequently -

Snow / flooding (happens every couple of years)
Mud (just general fields, hills, nothing cross axeled)

I don't do any serious off-road, but might if I had the kit - and if im buying kit, i may as well consider this.

The main reason for the diff stuff is simple mud (and snow which I hear mixed reports on the Detroits, but no one specifies which one). But I need to maintain the ability to drive down the motorway... I do very very little town driving though.

So it's motorway miles or work.
