ARB Air Locker?

I've got a desire to put one in the back of my 1994 NAS D-90..

Which ARB part is the correct one to order for the diff?



Thanks!

Don

If all is well in your rear axle, you should be ordering RD128.

I considered the Ashcroft, but there's an ARB dealer close by. I imagine support and maintenance is a bear dealing with the time differences and distance.

Thank you for the other replies. Will order that kit.

Second question:Compressor?
CKSA12 - small, light duty
CKMA12 - heavier than above
CKMTA12 - says it will inflate a 35" tire in under a minute..

I'm thinking the CKMTA12 - I hate reinflating my tires at the end of the day... currently takes me 5-7 minutes per tire, and I usually overheat the portable electric 12V compressor I usually carry.

I had the CKSA12 and CKMTA12... I'd go with the big one.

Support? Buy something that won't break... The Ashcroft has a better design for less price.....

I would not even consider an ARB compressor. They are way overpriced for what you get. Viair is the best choice.

Or if you have room, engine mounted. It takes me an average of 30 seconds to fill TWO tires with my truck.

Engine mounted - as in pulley-driven?

not sure I could manage the space in the engine bay... I'd have to fab something up and run another pulley or make room for it somewhere... I could just remove the heater core - I'm not using it anyways (I put in a Espar B1LC gas turbine heater to replace the passenger under-seat heater). I've just been too lazy to remove it - plus there was always the chance that if I ever sold the truck, I'd want to take the heater back (it was REALLY hard to find).

I'll have to think about that one...

That's interesting, I have heard quite the opposite. Talk to Bill at GBR for a while, he wouldn't put an Ashcroft locker anywhere near one of his vehicles.

If you have the room, the Viair dual 400C kit is a very good bang for the buck. around $300 (plus a small tank) and 4.5 cfm. If it were me, I'd add a second lower pressure switch, so only one runs as high pressure and the second kicks in at low pressure, such as when filling tires.

Gee, there would be no bias in a statement from Bill, now would there seeing as Ashcroft is one of his biggest competitors......

I would love to hear his reasoning. http://www.ashcroft-transmissions.co...ewCat&catId=89 1300 sold with zero failures.... But I guess Bill is calling Dave and Ian liars....

I'm not sure he's so much of a "competitor" as he has/does sell Ashcroft units.

Hearsay aside, I personally don't see much of a reason to go with an Ashcroft locker in the United States. ARB has such a presence here in the states that it is trivial to get service or parts.

On the other hand, if one were to choose a locker while driving in Dunstable, then there would be a big advantage to buying from Ashcroft as his shop is a short drive away for service.

I would imagine that, all else being equal, having to service an Ashcroft locker vs. an ARB locker in BFE Utah would favor the ARB for that reason.

It is a consumer's choice. Normally I look at price and quality and decide from there.

ARBs do have reasonable failure number based on my own experience. Ashcroft have purposely worked at designing out the items that fail and since they have many years of supplying ARBs, I'm sure their knowledge of what actually fails is a lot better than most people. It seems to have been successful. I've never heard of an Ashcroft locker failure in person or on the internet.

You would think that ARB would make design changes to address the failures.....

I believe ARB did make a few changes from the RD56 model to upgrade for the RD128. John, what kind of failures have you experience? The ones I hear the most are air leaks.

Ashcroft is able to focus a lot of time and effort on the one vehicle and has a lot of vehicle specific experience.

ARB makes them for every vehicle and there are much bigger markets than Land Rovers to focus energy on. Toys and Jeeps are the big markets.

I used to live in Australia and non of the Land Rover enthusiasts there would ever use an ARB, at least the ones I met, based on the failure rates.

Ashcroft is worth looking at. Superior product (0 failures to date) and the price points are similar. John is bang on imo.
