Hi all. First time posting here so please go easy I'm also sorry if this has been asked a million times before. I have been told that +2 inch springs from a disco 1/defender90 would give me between 3 and 4 inches of lift on my p38 would anyone be able to confirm this?
Many thanks
 
I would agree the past 4 I've had have been on air but the previous owner converted this one to springs about 10 years ago and absolutely gutted all of the EAS system and I'm bored of catching the back boxes and the crossmember everytime I go over anything remotely larger than a speedbump

What are you wanting to achieve? And lifting from where? What is your datum point?

Thanks for your reply, ideally I would like to achieve a minimum 3 inch lift without using any blocks under the springs
I currently have a standard height spring conversion on the car and I have already have some +2 inch shocks and have made some 1 inch spacers for the shocks ready to go on the car so would like to have some springs that would make the most of the +3 inches of shock travel I will have if that makes any sense
 
That and brake line modification, steering linkage, and maybe (I think :)) auto transmission cable.
Brake lines and steering wouldnt make any difference I believe as I wouldnt be taking the lift any higher than the air suspension would go on a standard car, and I don't see why I would have to do anything to the gearbox as I am not lifting the body on the chassis although I may be wrong

Why 3”? Is there something you are trying to achieve?

I’ll have to dig out the spring specs I’ve got on mine. In the mean time there is info in this vid on my channel.

As far as I'm aware thats how much lift full height would be on EAS so I'm just trying to replicate that height on springs if it's not possible I'll have to settle for a 2 inch terrafirma kit
I appreciate the help I'll give the video a watch
 
Surely the diff's would ground before the back boxes or crossmember ? Maybe the springs are lower than standard height ?
Not at all. The p38 has a loong wheel base and relatively small wheels. Off road they belly out all the time, even with the EAS in the raised off road mode. The breakover angle is pretty poor. It does depend what sort of "off roading" you are doing. But anything 'technical' will be an issue in this regard. I cover it in my video above.

The p38 also has quite a long rear over hang. I've broken the rear bumper on mine where it has impacted the ground off road.

The springs are standard height and light duty so not really up to either having the plant trailer + digger on the back or having 100+kg of tools in the back, but mainly its the approach and departure angles that are a problem when green laning

ok, no worries if you don't want say. Just curious what you are doing with the vehicle.

As for heights, not sure. The extended off road height was only a couple of inches over the road one I think. There is a non user selectable 'super' extended mode which is meant to activate if beached.

I'd say my p38 is lifted more than it ever did on the EAS. Overall I think it works pretty well and I know some guys in Oz and the USA have run similar lifts.

One thing of note is the steering wheel is now not centred. I believe this is due to how much lift there is that the panhard rod is arching round pulling the axle off centre (you can see the tyres stick out more on one side than the other). It ideally either needs a panhard rod relocation bracket or an adjustable panhard rod. The latter I've often wonder if a D2 one could be used, but haven't had confirmation or tried as of yet.

Obviously the vehicle sits higher, although I think it rolls less and still handle well. Although should you need to the 'Moose test' it probably wouldn't fair as well as a standard EAS in the motorway ride height.

I'm using +2 Terrafirma shocks. Not quite as smooth as the EAS. But I couldn't find any other +2's for the p38. They do sell some adjustable damping +2's as well. I may well try these at some point. I also have extended brake lines.

Off road the vehicle is much better than on the EAS. It no longer bellies out in places it used too and I no longer hit or break the rear bumper. Downsides, not so good for towing. I have the factory detachable tow bar, which now sits too high. If you have the fixed tow bar a drop plate would solve this.

I do have a slight rumble at 70mph. Although I'm having a few balancing issues with the tyres at the moment. But I do wonder if it is the prop too, as it must now be at a more extreme angle. Something to investigate, but hasn't really been an issue.

I'm not running massive tyres, although you easily could. I'm also considering swapping my current springs for some +2" ones from Flatdog. I'm sure it'll reduce the clearance off road, but would make it better for towing. Which for me would be a better mix. As I have another more extreme off road vehicle and I'd like to use the p38 to tow more.

For the springs. They are:

BA 2105 (front) and BA 2102 (Rear)

Which are Bearmach springs. Although there must be a part number cross reference somewhere, as Bearmach no longer exist.

Great thanks for your help, the car is an all rounder for me, I use it on the farm a lot so do a fair bit of towing I also do a lot of green laning and the odd pay and play day I understand the compromise of lifting the vehicle and that there is a lot more to it than just chucking a set of springs on and hoping for the best lol.
Ideally the end result would be something close to a 3inch lift and running 265/75/16 tyres

Sound a bit like 300 bhp/ton.

Depending what you're doing you might want to look at Ashcroft Airlockers. The viscous coupling means you have to use quite a lot of throttle which isn't always ideal in mud.

a rear locker is definitely on the list but unfortunately the list is growing by the day and starting to get quite expensive!
 
Terrafirma has a complete kit that they say has 4 inches of lift. I would contact them to ask if other changes need to be made to the vehicle after fitting.
