Thanks a lot! A couple more for the road (when it's actually clean)...........

Oradba69: This looks like a very interesting place to install the compressor.
1) Looks like you ran the switch right there as well?
2) How well does the smaller compressor do when airing up? I had the twin in my JKUR and it was pretty quick.
3) Did you make a custom bracket to get it mounted there?
4) I don't think I will be able to have a 2nd battery as I have a 2014 model but I always just left the vehicle running with the twin and never had a problem.
If you want to PM me a response that is fine as well. Thanks for the info!

Agreed, Scott. The deluxe bumper on my trooper was much lighter than i was expecting. Maybe 65-75lbs...

Sorry for only replying now. Currently on a trip and will beback in proper civilisation next week. Have only used it once and even though not very fast the convenience and reliability should serve me well.

Suspension Spacers
I was talking to a Land Rover Driving instructor about Johnson Rods and the Gap tool. He said if it was his he would have a machine shop build spacers for the suspension so you not wearing out the air bags. I have searched all over the internet trying to see if anyone has done this and I haven't been able to find any information on it. I thought this forum would be my best chance. Anybody have any experience with doing the suspension spacers?
Thanks,

Some LR3 products out there:
http://store.toddcosuspensions.com/larolr3diiii1.html
Not sure if the springs are the same across LR3-4.
The discussion around spacers has been that some claim that relocating the top of the spring/shock assembly puts it in a position to contact the control arm at certain suspension positions. The result is claimed to be the eventual wearing of a hole into the airbag and a corner that won't come off the bump stop.
For a virtual eternity, 4x4 trucks with independant front suspensions have had lift kits that essentially position every suspension pivot lower in the chassis - combined with longer or spaced out springs. This gives a lift the same height as the amount of relocation, but maintains OEM suspension geometry and usually OEM travel also. I don't see this 'mainstream' type of lift working on the LR3 without major engineering.

Not sure how the IIDtool or the rods will cause this?

My thoughts (our thoughts) exactly.
The air bags have a specific roll-over point at each height the suspension is set to(easily recognizable if you stick your head under the car and look at the bottom of an air bag). As the suspension compresses or lowers, the bag is rolled in more on the bottom - on droop or a raised suspension it is the opposite; more of the bag is unrolled.
This roll-over point is obviously the area of highest stress for the rubber and the first spot where older bags tend to start to leaking when they become worn and dry rotted. At times you can actually temporarily stop a bag from leaking by moving the suspension up or down to get the leak away from the roll-over point to where it is in the flat portion of the air spring.
I'd actually put forth that changing the suspension's height settings more often could possibly extend the life of the air bags as the roll-over point is being shifted up or down more often so that more areas on the air bag are stressed - rather than the same spots in the rubber being stressed throughout the life of the bag.
Spacers: I do not have enough experience with the LR3/4, but on a L322 Range Rover, spacers are a beneficial because the suspension runs out of travel (droop) very quickly on the front with a lift. Has nothing to do with wear, though.

The few comments I have read about the spacer on top of the air spring for the LR3 was that the bag could contact the other suspension components at the extreme range of its down travel. This could puncture the bag or where a hole (from contact). I seem to remember someone stating that a bag became over extended and "folded". That seems wierd and quite possibly an incorrect recollection on my part.
The only spacer I remember seeing was around 2". Could a 1" or 1.5" spacer work without the same issue? It would regain part of the rod lift. I am not a mechanical individual (metallurgist
) so I ask my betters in this area.
So with regards to the L322, do you feel that the spacers work well and don't cause the same issue?

Question for Scott,
Do you think it would be possible to have a review with your thoughts on the lockers? I think it would be nice to hear what your thoughts are on the truck with/without them. If you have an appoximate installed cost that you can base a "would or would not buy" based on a percieved performance, it would be a nice data point. Are they something you would add again? Is there an approximate comparison to another set up you have driven?
Thanks for the excellent write ups and all the work you guys have been doing!

Be very cautious of the spacers. While not 100% confirmed to be a problem, there is enough evidence to say that are a very big contributing factor.
Even just a bent shock or failed bump stop (inside the shock) can cause the upper a-arm to contact the airbag. It is very very tight up there.

How about this Landcruiser 200? = D
Digging the nice LR4's though. A diesel LR5 might bring me back to the fold... my Discovery had the entire engine yanked at 20K miles, among a host of other challenges.

Scott, would you be able to expand ion this item? I am interested in learning what you have learned and what the final compliment was? AApologies if this was mentioned but I don't remember it in this thread.
