detroit in the rear

GINGE · Oct 21, 2011

So,

I know that most of the advice on the web says that sticking a detroit locker in the rear axle on your 90 is a bad idea. BUT, there is a few people around that do run them.

Sooooo, does anyone here have one fitted and if so what is it really like?
Im not an agressive driver and so dont drive to quick anyway, let alone corners. Is it likely to just twitch and send me into a tree basically or can you sort of predict the over run?

Ive been thinking about lockers for a while. Would like fit and forget, but if the detroit will give me issues then im pretty set on getting ashcrofts new airlocker and air system.

I dont mind a combination like a detroit inthe front and air locker in the rear, but as with everything id like to do it within reason but do it right.

Thanks in advance

detroit has to go in the rear, as its permenantly locked until cornering, then disengages and re_engages back on straight,you can use lsd in front axle, ive got a detroit in rear of my 110, its a bit twitchy but the offroad benifits outway the on road manners, you soon get used to it, my mate in a 90 has arbs front and rear, we both run simex tyres and not once has he got any further than mine, so you may find you dont need the front locker

Would that be a air locker? thought they allowed for a slip lock type operation, and when air is put to it the it is locked up?

arbs are air lockers, detroit is permenantly locked

Not from what I have read about Detriot lockers They are made only 150 miles from me. Could be you don't have full access to all there product line.

You are right they don't do air, but they have 4 different full lock, lock with slip on cornering and a new electric lock, I'm going to find more info on this one

cant beat arb's for on road use as its just the same as standard diff when off

Oddie · Oct 21, 2011

Detroit is NOT permanently locked, it locks when it senses significant slippage, ie NOT when yer going round a corner. Having done lots fo research into both, and having weighed up the costs and work required, I personally would prefer a detroit to an ARB. You can put detroits in the front as well, but it isn't advised as they can lock up on corners, which you don't ant with the wheels that are steering.

Detroit make a lsd diff for the front so wont cause problem on corners

your wrong the detroit is the permenantly locked locker, the one your thinking of is the detroit truetrac which is a limited slip diff,

Fur Trapper · Oct 21, 2011

Oddie they also make a full lock for the rear diff. Just go to there home page and have a look

detroit locker.com they have 4 different lockers

Griffdowg · Oct 21, 2011

trapped the detroit locker is exactly how John has described and yes it should only be fitted to the rear as its 100% locked until it needs to 'slip'.

I think you are confused with the Detroit Truetrac which is a limited slip unit (LSD) this basically winds up an internal gear against a backplate as one wheel looses traction forcing the drive to be transfered to the wheel with traction. Its all good till you lift a wheel then it effectively stops working but you can apply a little 'left foot braking' to fool it into thinking its got traction and it will just edge along till that wheel finds the ground again.

A good example of the effectiveness of the detroit locker offroad is shown here: widget3's Channel - YouTube

50seconds in you see my 90 lifting its front wheels and still motoring through. The others running open diffs get cross axles and lose drive (with exception to the D3). The detroit truetrac would not have been able to do this so efficiently.

hope this helps Ginga.

edit. It took me a few minutes to write this so I missed a lot of the conversation!

oh...can't remember, but did look into it! Seems a bit pointless permanently locking a diff though.

Might try it on me works ren-**** meg-****!

Griffdowg · Oct 21, 2011

Yes, last I heard he was 80 miles away stuck in Traffic! shouldn't be long.

Still yet to try my truetrac out, hopefully soon now its fitted. got to get the front in also.
