SubscriberI wrote to Arnott Inc some months ago suggesting that they might consider releasing the Gen 3 design with reduced spring rates at normal height to reduce the harshness on broken bitumen and corrugations... they replied that they no longer did "special orders"...
I have the bog standard air springs and shocks. I recently replaced the worn Cooper H/Ts with the Bridgestone D697 (240/70/16). Obviously the ride over bumps is still somewhat muted because the tread is thick and rubber still soft. I was interested in others' comments about the ability of the BritPart foam cell dampers to reduce compression shock. Would seem they let the air spring do its job compression-wise and compensate by increasing the rebound effects... interesting.
PS: I've mentioned this previously (I think) but my front bags have both Ford and LR embossed logos and part numbers and are sealed with a crimp. Apparently they are specified for "hot climates". They also call out a different front damper part number...but they are very difficult to get hold of and I have no idea how they vary, if by much at all, from the standard front shock.

What's your other drive Ron?Originally Posted by p38arover
I regularly drive hiluxes and 100/200 series tojo's at work, and even our Dmax at home. Compared to all of them, the P38 is a magic carpet!
And Hoges, I emailed Arnotts a few months back asking if they'd consider a longer bellow and slightly longer piston for those of us who are keen on travel and keeping tyres on terra-firma. I got the same "auto-response" - we no longer do custom orders...
Slack...

Hi
Mine has Gen II's fitted and when I changed the shocks the ride became a little firmer. The original shocks were pretty shot and I had the bouncy castle effect happening.
The whole car feels much tighter and much nicer to drive. While not exactly Magic Carpet it rides better than pretty much anything else I get into!
Interesting that the Gen III's are actually firmer on normal setting

You need a jag if you're after that wafting along sensation.

SubscriberThe BIL recently sold their elderly Prado...had nearly 400,00 km on the original 2.7L petrol engine /drivetrain. Now it was VERY noisy in the cabin from diff/gearbox whine, however, dare I say it, the suspension performance over corrugations etc was very good. The ride was not bouncy, it was compliant, steered well in corners. Road imperfections/corrugations didn't cause scuttle shake.. perhaps it was the control arm bushes and chassis-body mounts. Whatever, the vibration/harshness was very well damped.
My understanding is that springs can be built to have varying rates depending on the load/shock, whereas the P38 standard airbags are fairly linear. Perhaps this is the "problem"...NO I do not want coils on my P38!

Major part of the heart and soul of AULRO.comI'd like to drive. one after the other, a P38A on coils and one on air springs. Ditto for a Classic.
I think I preferred the ride on my coiler classic to that of the P38A.
The P38A is, however, much quieter than my '86 classic was.

SupporterIt is possible to tune an aispring to be rising, constant, or even a falling rate spring.
I felt the original springs were too floppy at the front on hwy mode, and couldn't control the weight.
But the arnott springs rise in their spring rate quite rapidly, giving a more 'dumpy' spring.
I think a shock that had slightly heavier rebound valving would suit the spring better. Unfortunately for you Ron, the bilstiens are known for having very strong bump valving.
But they aren't like that fully loaded, and even when fully loaded the handling is amazing on hwy mode!!!
