Spring over axle for lift?

[yorker]

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.

Yep. What he said ^^.

And, the addition of helper springs is normally only advocated when you need to carry extra heavy loads or hauling heavy trailers. These days air bags are a better solution that provide greater carrying capacity and are height adjustable (which springs are not).
