You should just replace the whole system with an arb compressor :sombrero: I've got a pretty good idea how if you're up to try it!

I thought the pressure was relatively high, as far as the reservoir inlet pressure. Is that not the case?

It would be cool to put the AMK version where people are installing the ARB unit under the hood.

After, my second front strut on my LR3 I replaced everything with the AB 2in lift coil set-up. I have not been in one situation off or on road where I wish I still had the air suspension. I also know I'll never have to make 26 mile trip back from Crown King on bump stops.

There is something to be said for peace of mind! How have you felt about the ride? Whats noticeable in terms of differences? Its 2 inches so roughly the stock off road height or the "normal" johnson rod height?

Actual failure. See post 247. Aside from air suspension they seem reliable except maybe a water pump giving up the ghost. The jag engine is very reliable and so is the ZF transmission. Those are two reasons I am thinking about taking the plunge.

One of my front struts started leaking at less than 60k miles. Now at 65k miles my LR3 is in the shop getting a transmission problem diagnosed (will not shift from gears 3 to 4).

So far, I had better reliability with my previous Disco 1.

Got mine from Lucky8, but they are available from a number of people in the states.

Probably late for you now. I ordered mine recently from Island 4x4 in the UK. It arrived in about a week. It was a pretty good deal shipped.

The truck handles a ton better at speed on the freeway, and high speed on dirt roads. In technical off road situations I have not once missed the air suspension.

As far as actually lift, I think it's more than 2in. However, I didn't do before measurements.

Looks great JHawk. How's the articulation?

Speaking of articulation, next weekend our club will have an RTI ramp at our Annual meet. For the heck of it, I'm going to run my truck up it. I wonder if they'll have an award for least flex?

Careful with those RTI ramps...

In theory it can't be as good, but I have not noticed any difference on the trail.

The LR3 platform (same as RRS) does "okay" on the RTI ramp, considering its stock:

 

[zelatore]

looks better than I expected.

Jhawk - looks good! And I'd say that's more than 2" of lift as well.

Up near Truckee last month, an LR4 we were with had air suspension issues. He broke an airline and obviously dropped to bump stops. I have 94k on the lr3 and I know the previous owner (Sasquatch who pioneered the rods) replaced one strut. Once she hits 120k, I will probably convert to coils as everything becomes a wear item like my P38. Over time, air springs leak, rubber O-rings crack, valve blocks will leak and the compressors need replacing. I think the air suspension is phenomenal when it works well, but as these trucks age, parts will fail.

On a side note, the coolant bleeder valve disintegrated on our LR3 going over Donner Pass. This is a $12 plastic part that should be changed at least every 50k miles. You will see it on top of the engine and it is a 5 minute change but is prone to failure and a common fault. I upgraded to a metal nipple and keep a spare plastic one for other LR3/RRSs.
