GDAY all , with 3 old range rovers and 2 Discos in the back yard Ive decided to build one up into a decent road registered bush basher , I used to have Maxidrive diffs and difflocks in front and rear of the old 78 2 door , which I sold off,. I was amazed to find out that the maxi-drives no-longer exist. Can anybody suggest a diff-lock for the rear diff ?

ARB airlocker.
I have a trutrac LSD in the rear of mine. Not as positive as a difflock, but pretty good anyway.

OK ,seems the ARB is the way to go , wonder how much HP/torque can you put them , or will the axle be the weak point or the t/case or the tailshaft

If you name has any indication to the vehicle you wanna fit the difflocks, then stock banjo style rover diffs ain't for you;)

You probably wont break the ARB locker.;)
Depends on tyre size and diff ratios and your driving style. If your after big strength forget stuffing around with rover diffs uless you prepared to use Toyo cwps etc;)
If you want to use Rover ARB lockers and 24 spline Hi-Tough shafts with pre 86 Rangie or AEU 2522 CV's will get you going.

Yeah , I was thinking of using the R380 box out of the disco into the 89 vogue with a alloy headed 383 stroker ,then detuning it with a smaller quad throttle body on straight LPG ,will be alot of fun !

Your kidding right? R380 with a 383, you'd wanna have little tyres and a light right foot
Whats the specs on the engine? aside from alloy heads, compression ratio? cam?

current spec ,355 stroker 12:1 comp 233@50 backsplit 108 LCA's solid cam 810PG quad throttle body Straight LPG 440Hp 430ft/lbs , yep a bit much for a 4WD app ,(13.78@101MPH in a 2 ton Statesman) probably pull the cam and fit something in the 212 / 210 range and some early heads with smaller valves and a standard exhaust . Will just have to learn to Drive within the limits !!!

Mmm dont think the R380 will like that much maybe an auto or an LT95 would be more appropriate.
You will need a different carrier in the rear diff ARB, Detroit Locker, Trutrack or something.

Thanls, djam , i wonder if anybody has ever tried to graft in some 9 inch centers or would the rear center balljoint/A frame get the in the way ?

I know Dave Ashcroft in the Uk was doing a direct replacement

I know thats not what you are suggesting and I dont see that what you are suggesting is impossible.
A lot of people use Toyota components Jack Mack was the originator to my knowledge Jack McNamara - Differential Specialists (http://www.mcnamaradiffs.com.au/products.html)
You could always use a Salisbury it would be strong enough but a big heavy B@stard.

There have been plenty of 9" rears built for rangies.
Sounds like you would be best off with a salisbury rear - or 80 series axles F+R.

I've got a detroit "soft" locker in the rear of my 110, love it.Works awesomely(not sure if that's a real word....:cool:), and there's not much can go wrong, no air lines etc.
You can put it in yourself and cost will be less than a grand all up....:D:D
Apparently the old detroit lockers used to unlock with a bit of a lurch when going around corners on sealed road and some disregard them because of this.Mine is a new version hence the name "soft" locker...I can feel it unlock in above situation, but only just and it's not an issue.
I like the fact that my diff is always locked, until there is a differential in tire rotation speed(eg a corner), so it's always ready/locked rather than having to make a decision to lock it in and flick a switch, which may sometimes be too late.
I've only heard good things about the ARB airlockers, but for me the detroit locker was a better way to go...

Thanks extreme6.5 , but I think that would mean I need a Salisbury diff , think I might try to get maxidrive centers and axles , in the mean time Ill get good at changing diff centers . I had maxidrives front and rear in my old bush basher with a 5.2 (4.4 P76 bored and stroked) and never had any troubles .

A Salisbury will give all the strength you need but you will need HD axles I personally use Maxi Drive Axles but they are even a bit light compared to the diffs actual capacity.
Speak to Keith at Rover Tracks if you need heavier ones.
I will second the Salisbury Soft Locker endorsement I think they are fantastic I have run one for 4 years without issue.

And I third it, best and simplest traction aid I reckon. I do most of my driving on road at the moment:( and hardly know its there
