I remember doing some research on the 30 spline. I talked to Keith at rovertracks about it (a year ago) and it seemed like a significant chunk of money just to inrease the spline count. Sure, it'll be stronger but you'll basically be turning your rearend into an american Dana 60.

Also the 30 spline detroit will cost a lot more since its a full carrier replacement instead of a "lunchbox" type. Even still, you are retaining the same axle shaft diameter. Overall, it seemed like A LOT of money for NOT having 1.5" axle shafts and 35 spline.

A better solution is to go get a pair of 4340 axles made up. The local axle shop here said they'd do it for $300~$350 for a pair. This way, you could buy the salisbury locker for cheap, install it yourself (save about 100~150 there) and then install the new HD shafts. Maybe cheaper.

A buddy of mine bought his disco detroit from PORC off road. Got it for a killer deal. Same story for other friends with non-rover vehicles, they gave a good price. I would think the same would be had for the salisbury locker.

Wish it were as easy as dumping a 60 lunchbox in there.

Unfortunately, thats for a 2 pin carrier while the salisburies are 4 pin. The salisbury diff is like a Dana 70 or a 14 bolt diff.

I haven't looked into it, but it would be cool if a 70 locker could be used. Then you could get your 35 spline and 1.5" axle shafts. I don't think any rover is capable of destroying that.

This is exactly what I am running in my truck. The Dana 70 "No Spin" drops right into the Rover carrier. Next you will need to work out the Stub axles which you would source through Jack McNamara or RT. The Stubs I make are shorter and designed for Disco hubs but will work.
While not a stand alone product they can be had. You would also need to machine the hubs for the bigger bearings required to go around a bigger stub axle. If you don't have rear disc brakes now is a good time to do that too.

Wow, the 70 no spin drops right in!!?? Thats cool.

On the spindles and such, I know the jeeper guys bore out the spindles on Dana 60s all the time. I wonder if there is enough metal to do that to a rover spindle. Definately would be a cheap and easy way to go bulletproof.

I have one other question: does anyone know if there if much difference between a D110 and a 109 salisbury carrier? The dana 70 drop in appeals to me.

Jack,
James Gall installed a Detroit in his Sal's under his Disco. He paid less than 300.00 for it, but I can't remember where he got it. You may PM him. But, he also promptly busted his stock 24-spline Sal's axles. He went to the GBR Sal's HD axles, now.

The 110 you have may be light enough to not pose a problem, but if you're going to do it, IMO, I would jump right to the 30-spline option.


When James Gall broke the 24 spline sals axle did it take out the detroit as well?

I've broken a 24 spline shaft in my salisbury. It only damaged the axle shaft (which is to be expected) and my pride.

The Detroit is the way to go :applause:

Is there something different about the D70 Trachtech Detroit No-Spin?

I've nearly always seen a snapping axle shaft take the Detroit with it in Rover 24spline coiler applications.

What were the circumstances surrounding the failure? Was there a common denominator ie. heavy foot? rocking the truck trying to get unstuck? Just curious. I drive with a pretty light foot and whenever I feel the truck start to gain traction I always let off on the throttle. I have yet to snap an axle, knock on wood, but maybe it's like the old skiing adage. If your not falling your not skiing hard enough. Which by the way I think is BS.

Stock axles are going to break if you run a locker.

It's not a matter of technique or ability.

If you are abusive you will break them faster, but even if you are gentle over time you will fatigue and weaken stock axles and eventually they will fail. The stock axle material simply was never intended to even come close to handling the stress of locking differentials.

If you run an ARB you can break them and replace them with more stockers which will also break.

If you run a detroit, chances are if you break the axle you'll take the detroit out with it.


I think you CAN baby stock axles with a Trutrac and make them last.

I guess there is just no way around being cheap. I was going to use the stock axles in the Sals but sooner or later I'm going to have replace them anyway.

Well, my axle broke while doing a powerslide through downtown.

So there I was...at the stop sign when I across yonder roadway I saw a bunch of girls I knew. So I had to show off. I spooled up all 4 of my cylinders (yes, I giggled the wires so all 4 were being used), and sidestepped the clutch. Then I grabbed 2nd and jerked the wheel hard right. The rearend broke loose and I immediately countered with left steering.

I had been doing pushups for the last few months so my arms would be strong enough to make it happen. Manual steering can be a little difficult sometimes.

So there I was, in my 109, doing a powerslide, and impressing them. All of a sudden: BAM! The truck straightens out and shakes like a dog emerging from a lake.

Then I drove about 1000 miles on one axle shaft. It was interesting but didn't have any problems, just annoying because I'd get on the throttle, I'd go right, then off the throttle, I'd go left.

The full floating axles have an unbelievable ability to take damage and keep going, and NOT have further damage. You shouldn't be concerned with breaking an axle because it probably won't cause any other problems and you'll still be able to progress forward.

But if you are truly worried, then you can order a replacement pair of OEM shafts from one of the shops in britain for cheap. Thats what I did, got it shipped for about half the price of a used shaft in the US.

A breaking axle can take out a Detroit in a Sals I've done it but with an axle I turned down over and over again to see where the breaking point was. The Stock Sals axle is a pretty nice piece of work, Not teh best but far better than what you would find in a Stock Disco or D90. They can last depending on all the usual reasons axles break.

As for Boring the Spindles to get 35 spline 1.5" axles in your sals. Sorry but no dice, I'm not sure the wheel bearing ID is 1.5" so you would need to replace the stub axles

How would you say a stock sals axle compares in strength to say a GBR/MD HD 24spline axle for a d1/d90/rrc?

Wouldnt going to a HD axle like GB put more stress on the Detroit? I would much rather have an axle snap than have my axles so strong that the Detroit gives before the axle. Is this even a valid concern?

No. What breaks the Detroits is "Shock Overload". Meaning, when an axle breaks, the recoil is what tears up the Detroit.

the recoil shatters all the little "dogteeth" that engage the lockers.

not a pretty sight!

Kev, definately upgrade the shafts w/ a detroit
i've personally seen 4 detroits get taken out by broken axles
