Arnott air springs

jonny427 · Nov 7, 2009

Can anyone say if they have had problems with Arnott air suspension? I have heard that the valves have been known to leak from new. I am due for new springs but dont want to replace them with conventional coils or original dunlop spring unless necessary. Also can the gas shocks be fitted to Rangeys with air springs? Thanks in anticipation.

Ok chaps looks like Arnotts are good, next question gen 2 or 3, 3's seem to improve handling over gen 2's any comments?

Arnott airbags, what valves??? there are no valves in the suspension units, only an air line connector.

I have Arnott Gen 2's, I'm very happy with them, there is supposedly a lifetime warranty covering manufacturing defects.

Surely if air can go in through the connector but not designed to come back out again then that connector is a valve!

I repeat, it is just a connector, the air flows in or out under the control of the solenoid block and the EAS ECU, so it is not a valve. How the f@ck do you think it is possible for the EAS to lower the suspension?

Some customers had long time to seal the air pipe in the connector.
The tip is to fit the upper base first, then connect secure the air pipe before locking the lower base.

Gen3 improves handling : less body roll.
If you had bilstein to that, you won't recognize you Range Rover.

I've Gen III's on the front, Dunlops on rear, Koni's all round.

V. happy with set up. As said above gas shocks will revolutionize your motor.

Is someone willing to explain the difference in ride, like they say the Arnotts are stiffer!! but what does this do to the ride comfort as in hitting bumps, for instance - say if you drove over a corragated dirt track with Dunlops on, then replaced them with Arnotts and drove the same bit of track, which would be less bone jarring?

the stiffer the suspension - the more any bumps are transmitted thru to the occupants, but the less body roll you get. Motorway driving - soft suspension. tristy lanes - harder suspension.

Harder suspension means yu feel every matchstick, but it handles better. Softer suspension means a more comfy straight line ride, with the possibility of feeling sea?sick because the car will "wallow" more.

Some said Arnotts are stiffer.
First, which Arnotts are we talking about ? Gen 2 or Gen 3.

-Gen 2 have same rates as OEM but do not forget that a brand new airspring whatever the brand may be stiffer than the crappy old one full of holes

-Gen3 have inversed rates compared to OEM, result is they are stiffer on highway mode but much more softer in high mode. Amazing how they are much more comfortable on the trail and how precise they can be on the road.
Let's tell it simply, i now use the highway mode all the time (don't d o that with Dunlops or Gen2 since the highway position rate is softer thant normal ) because i have a 4.6 and i drive it like if i stole it

. For the days i want comfort and take my time, i simply choose normal setting

Gen3's have changed my truck, really.
If you have fear of loss of comfort, do not go with gas shocks. You can't have precise behaviour and comfort of OEM shocks (i'm not talking about airsprings)

Thankyou Both, It makes sense now as to the ambigous reply Igot from Arnotts when Iasked this question, they avoided the ride quality and kept raving how good they were on Highway compared to OEM's. here in Aus it's we can't drive much over 60 MPH and most if not all corners are posted at 35 MPH (they is in Metric of course, miles for my UK readers) so the ability for on road is not an issue, - and Ifind the dunlops to be OK in the bush. Thanks again will possibly stick with Dunlops and change them every 3 years.

Loss of comfort was my biggest fear when I changed to Gen III's, I thought it might lead to a harsher ride, but there was no difference whatsoever under normal driving conditions. The biggest difference you will notice is on twisty roads and roundabouts, the Rangie stays so much flatter. Had a ride in a P38 the other day on OE springs and I had forgotten how much body roll there is on roundabouts.

As has been said, I think shocks play a much bigger part in comfort.

The fear of harsher ride is what bothers me, as there are still too many roads around here that are not sealed, these get very corragated and to be honest the ride from the dunlops on this type of surface is not satisfying compared to similar rangie on coils. The bellows have to stay unfortunatly as the need to lower to bumpstops is required for a family member. Otherwise I'd replaced with coils long ago. Thankyou.

As said above the Arnott Gen III's give a more supple ride at standard height setting compared to OEM.

With regard to ride comfort on unsurfaced roads I spend a solid 30% of my driving on rough forest tracks and would strongly recommend a change to gas shocks, particularily on corrugated surfaces. While OEM shocks are probably softer when you hit a one off pothole their lack of rebound control makes them inferior on continuos rough roads such as you describe.

I went with Gen III's on the front for improved dive under braking and the added resistance to roll with the high engine upfront. I stuck with OEM's on the back because of lack of funds and some reported clearance issues at the rear. Coupled with the Koni's all round I have far better control all over with front axle 'patter', which was downright dangerous in some instances before, all but eliminated. I am very pleased with the overall improvement and genuinely feel that the ride is better than before.
