As I said immediately above this post, you can calibrate the air shocks where you want, and adjust the trim for each side manually on a per-ride basis. If you never plan to go to the stock "high" position, an extra inch on the air springs is probably okay since that's about the extension that they're designed to go to.

It sounds like what you'd like to do is get rid of the press-the-button-to-raise-the-ride and instead go to something that lets you incrementally adjust the ride height. Unless you work with the SLABS programming, you're going to be constantly battling it since that will be constantly trying to revert to the calibrated height.

 

What I was saying in the post was don't use the computer to control the suspension rather a completely separate from the rover system to control the air suspension.

 

The SLABS system will still try to fight you, unless you disable it completely. Otherwise the ride height sensors will trigger the SLABS to make automatic adjustments.

 

SLABS is already disabled on the rig i'm looking at/ talking about. If what I am thinking about will actually work I can have air suspension without needing to use the onboard computer.

What I am talking about is a completely almost analogue system where everything would need to controlled by switches.

IMO everything seems to work better when it has 2 positions on and off, because when it breaks you have a lot less junk to dig through to find the issue.

Everything should work unless you are saying there are other ride height sensors besides the ones that were used on the previous SLS system.

 

Those are the only two that I know about. I wonder how you would know when you've reached the safe height limits though (either high or low), without some input from those sensors.

 

My thought was once I got it all done and installed I would air it up to the normal ride height via measurement with a yardstick. At that point make note of the PSI and have a cheat sheet taped to the dash or something. As the bags go up or down so does the PSI with a little handy work I could even incorporate a low PSI warning to make something ding or chime in the event of a major leak or failure. At a certain point however if you have a major issue like you blow a line or something at high speed your screwed SLABS or not.

For the other heights repeat the process and just use a gauge to judge height and pressure.

 

The big problem with that approach is that it depends heavily upon what you've got loaded in the truck. Even a couple of people inside is probably going to change the pressure in the bags a fair amount.

 

Really what I see this coming down too is the time spent installing to reliability factor. Sure it may take more time to load the car up and take more measurements but whats the trade off in terms of the longevity and serviceability of the system as a whole.

 

I'd say that longevity would probably be comparable to the OEM system, since you'd be using the same type of setup that would be subject to the same types of stresses. The main issue with the Rover bags seems to be that they develop leaks over time --
as do any air springs.
Reliability might be less since you don't have the benefit of having had the system stress tested and the design refined through multiple iterations. Plus you're talking about using them in a lifted situation, which takes them into territory that they might not be suited for.

 

I think at the very least ill need to ditch the 3 inch and keep it at 2 inch which has been tried and tested, as for the management of the air ride ill wait until I get the truck and see what hardware is still there and what was removed based on that will determine what path I take.

Thanks yall for the help!
