Hi Keithy
you will have to educate me, I know of three PMs a couple that are not doing much at the moment.
I think Steve is also interested, don't want to step on any feet

That's ok mate, PM stands for personal message (or private message, either or).
I'm sure it'll work out either way, the shocks are fairly well priced outta the UK, so even if toes get crumpled, it won't be earth shatteringly devastating!
The early bird gets the worm!
That's me for another week of playing lift-kit fellas! Will be back at it next thurs, once the family have had their chance to enjoy my company as much as the Rangie does!
Key lesson this week - I'm not an engineer and air springs are not supposed to dislocate like coils. Nuts and bolts are the only solution here it seems!
Cheers

Keithy and Peter,
I realise this is your post, so I hope you won't mind me highjacking it. The subject matter is the same. And given I've copied your work, I hope you'll consider it a complement.
I have now extended the pair of rear height sensors using carbon fibre tent poles on the top arms to extend them from 150mm to 175mm. The bottom arms are set at 145mm from the original 120mm, but can be adjusted using the turnbuckle. Hope it works. The brackets in the centre are for the front sensor arms - I've decided to leave them stock and simply raise the attachment point on the radius arm.
Attachment 66558
The next photo shows the amount of welding I have in store. The spacer brackets unassembled.

The front spacers have parallel plates. The rear spacers are angled at 5degs top plate and 5degs bottom plate. I've still got to cut the 100mm pipe sections for the rear spacers. Will be a lot harder on the rears than the fronts due to the angle.
Wish I had a chop saw.
I'm glad it's you and not me, my welding skills are crude at best!Quote:

Your kit looks good! The 25mm extension of the arms is 23mm less than what I have done, but I am sure you will work out exactly what works for you once you have it all installed.
The reinforcing will certainly be peace of mind for you while driving! If they break then I'm in serious trouble!
Good work mate!
Keithy
Looking good. No problem jumping in. It's all for the same cause :) Only jealous that you might be done before me because my time has been diverted elsewhere.Quote:

But when the wheel is pushed right up, the rotation should be less than the single 50mm bottom arm extension due to the angles.. SO hopefully less likely to foul out or over turn the height sensor. I did an example drawing to illustrate this when I first looked into it.
I was looking at doing both but laziness made me wonder if I'll get away with just the bottom arm... Time will tell I guess once I finally pull mine out.
Thanks for pulling me up on that Peter, I mis-read the post!
Early starts and odd weather ill blame it on ;-)
Ha ha. We all have those moments.Quote:

Just a suggestion which keith has already heard. Your height sensor arms need to be bent to an angle which makes them move in the same arc as previously fitted. Simply lengthening them will make them foul on your chassis. Especially the rear ones. I believe if you extend the length of the rod poking out of the sensor a bit you will achieve a scenario where your access will end up 'similar' to how high it was pre lift but will give you your lifted height in highway mode(what ever you call it):(. Esentially a bit of research into fulcrum adjustments will be your friend here.
Just trying to help. Don't mean to step on toes:D.
Cheers,

I got a nasty reminder this weekend about the importance of the component matching and sizing for the air suspension components, sorry its so long....
Some time ago I replaced the standard air springs with a set of Arnott IIIs and because of their extra maximum length I fitted a set of Terrafirma +2" shocks at the same time. I've been following this thread with interest as I intend to extend things properly and all has been great for almost a year with several trips with beach and dune driving, until Saturday....
We went for a long weekend trip to Fraser towing a camper trailer, all was going great until about an hour into the beach drive when we got caught by surprise by a washout that was much deeper on the exit side than in looked, front and back bounced into the air as we went over and about a minute further on we got the slight rumble from the back end 265/75R16 KM2s touching the wheel arch liners as it went down onto the rear bump stops, the EAS control was flashing the extended height LED so all was not good.
I had a look underneath and the NSR height sensor arm was missing, broken off at potentiometer on the chassis and also just below the center hinge (so that was gone too), the other side looked OK but clearly one sensor reading full height and one reading normal height completely confused the EAS so it decided to drop the pressure on both bags. Fortunately, the potentiometer was still working and could be turned by hand to give more sensible reading to the EAS and after much trial and error this allowed it to re-inflate the bags to something near normal and pulling the EAS control relay made it stay that way.
OK, on with the holiday, the P38 is a pulling machine with car and trailer tyres all dropped to 16psi, we got through dune tracks that the jap cars were struggling with without trailers.
Anyway, on Monday on the way home we dropped off the trailer at Eurong and headed out to Lake McKenzie, its a long slow drive to get there, over an hour, through rough sand tracks but we made it OK. We even got most of the way back until we got the familiar 'bang'...'hisssss' from the OSR airbag.
The bottom 'R' clip had disintegrated and the bottom aluminium piston had tipped over onto it's side then been pinched between the chassis and axle plate, this tore the bag out of the crimp ring and released the air. Fortunately we were on a wider part of the track so we pulled over leaving room for others to pass, then it was out with the spare original bag and after a bit of struggle the replacement was in and the EAS relay re-inserted to inflate it back up to something like normal, then out with the relay and off we went again at a greatly reduced speed.
So, I'm now going to order a set of standard length shocks (I didn't know that these restricted the maximum axle travel when I got the +2" shocks) and I also need to get a replacement height sensor assembly, fortunately I do already have a spare Arnott III rear bag.
I'll also keep following this thread as extending the sensor arms or making them telescopic in some way to cope with a sudden extension without breaking is important for piece of mind, the +2" shocks will likely go back in eventually but only after the +2" extension to air spring base and bump stops has been completed.
