View Full Version : Adjustable Air shocks in the front?

Is it feasible to put air adjustable shocks in the front? Then you can have your two or three inch lift when you need it? A manual rock crawl setting used with the SLS or air bag helper springs on the rear.

Not sure what you mean about adjustable air shock for different heights.......

Just need the correct mounts and shock open/closed to suit the airbag.

Your shock mounts aren’t designed to take such loads, so no.

Spring perches is your old point so airbag and external shock mounts ala P38 would work.

It is possible for the p38a bag to fit in a d2a, but the ride is harsh over man hole covers. But on the flip side is amazing over speed bumps at speed. I would definitely recommend custom perches, a true weld on shock mount and firestone bags.

buy a range rover with air suspension [thumbsupbig]

Are we talking air shocks with the original coil springs or are we talking about replacing the coil springs with air springs and using the standard shocks that they come with?

Clarification is needed.

They come in manual?

I've wondered about fitting airbags inside coils in the front. I discussed this with an ARB expert who said the issue could be if an airbag failed at speed it could affect the steering and make the vehicle swerve.
I still think it's an interesting idea.

The original idea was to replace the existing shocks with air shocks. But I have been told that the shock mount is not strong enough. If you use air springs, you will need a perch to relocate the shocks. This is looking at the front suspension. Another suggestion is to use P38 air springs with relocated shockers.
I wonder if the D3 air springs would fit? maybe too wide.

You have to relocate the shock......mays well convert to full airbags.

Re: failure, look at the amount of car running on air.......either way if you had helper bags in the front there would be bugger all air in them as the front doesn’t really load up

Hadn't realized the springs would have to be relocated.

Bag in coil is only load levelling.

Doesn’t give a “lift”

You would be limited by the physical dimensions of the coil spring compressed/extended so there would be no gain apart from load assistance as Tombie said.
A proper coil replacement airbag with suitable shock is the only way.

I just wondered if an airbag inside a front coil could compensate for the drop caused by the weight of a bullbar and winch on the front in the same way an airbag in a rear coil can compensate for the drop caused by the weight in the rear and the towball weight.
So in each case the airbag would be an alternative to fitting stiffer springs.
I don't know if this is doable - it's just speculation.

It is possible Mick same as what is done when fitting polyairs or similar, good idea or not is another question.

That's cool. Would it work with ACE? I can't see why not, but...

They come in manual? mine can be put in manual mode and the gear chosen but clicking the auto lever forth or back to select 1st -5th gear, rarely use that feature tough.
I have been known to sit at the lights and a lifted hilux tosser pulls up next to me, so for a stir , I flick the raise button to raise the Rangie, it auto lowers again at 50kph.

Yes it would work and would result in a softer ride that is well controlled. The best result would be soft bags, soft tuned shocks and stiffer swaybars to control the roll with ace.

Maybe I should retrofit ace to my disco once I redo my bags and shocks.

Theoretically yes...

Financial would make a $140 pair of coils (a Bar is a fixture not temporary load) far more viable [emoji6]

Spring don’t need to be stiffer either, just longer.

Stiffer roll bars with ACE [emoji12] don’t think so [emoji41]

Stiffer sway bars only if the bags and shocks are tuned independently to body roll. The largest Firestone bags that kinda fit are 160 lbs front and probably lower again for the longer bag in the rear.

You do realise ACE *is* the sway bar!

yes, but there is still a torsion bar there.

Oh good grief... the Torsion Bar is directly connected to the Actuator and is part of the ACE system.

The ram acting upon it changes is resistance. You certainly don’t need to attempt to change it.

yep [smilebigeye],, but until you actually lower the car onto the ground, its all guesswork on how much longer,,
theres no guesswork needed with bags,,
but as the added weight should be constant, and you have to remove the springs anyway[bighmmm]

but,, if you connected the new bags to a compressor and wired that to the Raise switch on the D2 dash----- [bigrolf]

No guesswork in it at all.

Weight, compression, current spring rate..

A few calculations and you have your answer [emoji41]
