Spring over axle for lift?

[series3dc]

Just curious on thoughts if this would work on a series with stock springs. Seems like it might make the ride of the stock springs more compliant while giving a customizable lift. I would think it would also add to your load carrying capacity instead of reducing it like parabolics. Thoughts?

I never thought of doing this to my Rover, but it's the set up I have on my old home made trailer, coils over leafs. It definitely increases the carry capacity. However, I did notice that when the coils were added on, the trailer bounces around a bit more when I hit bumps, don't know how it would effect the control of steering on a Landy.

I did it on a CJ-8 Scrambler a long time ago and it actually was ok. It had a little more sway but not much else was that different.

You will open yourself up for a serious round of modification and fabrication.

Read this thread on LR4x4 and take their advice about searching and reading further on that forum.

Just to help you out, use this lmgtfy link.

Ooops. Sorry. I read what you wrote in your subject line, not what you linked to, which is quite a different thing.

Have no idea how that would affect the geometry on the Land Rover. What I can say though is that it is a hell of a hard way to get around having the springs reset, which can be done in a weekend. Then after your springs are reset, you can feel assured that your vehicle is still safe and not likely to throw you into a ditch off the edge of a cliff.

Those links are useful reading in any case.

Not mine.
This Danish Land-Rover has springs over axles. Standard Land-Rover leafsprings are really rigid, so I don't think you need the coils. This 88" also features a 3.5 Rover V8, but haven't seen it for years.

What you have linked to is more of a "helper spring". Traditionally SOA is where you put the entire leaf spring on top of the axle vs. beneath:

Thanks for the photos. They give some indication of the amount of work required to achieve SOA. Others take the coiler route, and in these parts people get old Rangie classics with their superior 100" chassis and put a series body on it.

Just thought I'd mention that in some parts of the world, those modifications are not legal or need certification. The adaptation used to be fairly common here about 30 years ago. Since then, better solutions have been created. In some cases including the removal of springs altogether.

The trend with competition/winch challenge trucks here is not to raise the vehicle but lower its COG. Articulation is more important than diff clearance inmost cases and in those where it is critical people fit portals and use larger diameter tyres (36"-40" seems normal at the moment).

Thanks for all of the replies and info. I meant to state spring over leaf conversion. The spring over axle gives too much lift for what I am trying to achieve. I only want about 4 inches and it is my understanding the SOA gives about a 7" lift. I am planning on doing it on a 1962 109. It is cheap enough to try and I can always switch to parabolics if I decide I do not like it. I've just heard of the parabolic sagging and uneven problems and also do not think they will give me enough lift even with extended shackles.
Thanks

SOA doesn't have to give you that much lift, Ideally the way it is accomplished is with dearched springs, and in the case of a Land Rover with longer springs. This gives you FAR greater articulation with a modest lift. Usually you alter the front so you can use rear springs on it. If you wanted even better articulation you could look beyond the Land Rover parts bin for longer leaf springs. Land Rover front springs are very short and stiff and do not allow for much articulation. SOA can be a very economical and well performing modification if you plan it out well to begin with.

Parabolics will give you a slight lift initially but so will any new springs, it usually settles out over time. Longer spring shackles will mess with your pinion and caster angles. Why are you looking for lift? A 109 can be fitted with 9.00 16 tires as is, there is plenty of room under there, it works better with a military/1 ton chassis but you can do it on a standard 109 chassis too. that is a ~35" tire with no lift. Your real problem is the pixie stick axle shafts.
