I'm looking into having my ride height raised... Not only because my rear suspension keeps hitting the bump stopper but as well because I'll need to change tires soon and want some badass monster truck tires on it. ;)
After a few measurements, to raise it by 30mm would be enough so to keep the access easy (the mrs. already complaints it's to high as it is when she has to slide down the seat on a skirt to get out of the tractor...) and that would be enough as well for a nice offroad tire when I come to replace them soon. Then, that will give me the final 2'' lift that I want to achieve together with tires and suspension lift.
After all the stuff I read, again, many many options available but I was looking for something way more simple than new spring kits.
Any chance to get the springs stretched with a torch or a coil spacer? Anyone done it before?
What do you recommend?
What impacts would this have on diffs, propshafts or shock absorbers?
Opinions appreciated...

Cheers!

Put a torch near the springs and they will fail in dramatic fashion.

I know this is done a lot to lower the cars as a cheap solution, thought it could work to stretch them as well...

Raising and lowering of P38s is done with the EAS. If you have coils fitted applying heat to coil springs could harden them, they would shatter if not tempered. Depends how much heat is applied. And how they are cooled.

Spacers then? Any special recommendations?

Don't do coils on P38s. But how about some of those things caravaners use to stiffen the rear springing whilst towing their over loaded tin tents. Sort of rubber insert that goes in between the coils.

I saw those for sale around the web but as you said, it stiffens the suspension. It's hard enough as it is now... Not very fond of that option.
 
Would love to, unfortunately that's not an option I can afford.
This whole debate of air vs spring is very old and the conclusion is always the same. So, lets leave that aside and think of a solution on current specs...
I'm sure there's a small slice of P38 on springs owners that would appreciate your contributions.

Lifting the springs will just give you more ground clearance and make the car unstable on the road. It will not alter the articulation in any way. And would certainly lead to drive line problems in the long run.

That was the idea... Have more ground clearance and have more space for bigger tires.
Also, the 3cm would be enough and I'm convinced it would not be too much for the drivetrain. Just about the same height as the EAS off road setting.
I use the car on a daily basis but for short routes (60-70 Km a day) and off road driving on the weekends, mainly sand, so stability is not really something I'm concerned with as I never drive past 120 Km/h. I drive at 80/100 90% of the time.

Raising the angle of the propshafts will will make them work harder. Specially the front one. Have you ever wondered why speed is restricted to 35 MPH when EAS is in extended height?

If yours is hitting the bump stops id be looking at the quality of your springs, unless its extreme off roading/articulation mine on springs never hits the stops (except hitting a hidden bump under water at 30 rear end nearly took off!)
 
Can anyone tell me how height should it be from the ground to the center of the wheel arch on steel springs?
That way I can measure mine and compare to know if it is at the correct height or if it is lower.

No because it's not supposed to have steel springs. Standard ride height on air is 470 mm from centre of wheel to arch lip. + or - 7mm.
