60 series with leaf over axle conv. issues?

Post by bushhogg4x4 »

just wondering if there are any things i need to watch out for when converting spring over axles,
how top heavy does she get?
will i need smaller/longer shocks
issues with sway bar?
is there issues with the front end when converting in short.?

and finaly if doing so should i run bigger wheels the majority of the time?

based on your questions it appears you need to do a lot more homework. doing a springover conversion requires a lot more than just bolting the axles under the springs. you will need to decide whether you convert to high-steer, or use a double arm. you need to cut the knuckles and rotate them to correct your caster and pinion angles. you need to investigate axle wrap prevention for the rear axle. search, there is plenty of good springover tech here on outerlimits. mostly, you want the help of someone who has done it before.

if you want to drive it on the road, you need to speak to an engineer BEFORE you begin.

agree, i had to do all of this when we sprung my 60 over.
also had to move shock mounts, get a custom front shaft and notch the front crossmember as the shaft would hit the crossmember when flexing,

i also comped in it with no wrap bar, as a result, i snapped a pinion and kinked both sets of springs.

as DD said, there is ALOT of work in a SPOA, but dont let that put u off

yeah i was just wondering whether to do a 2 1/2" spring lift OR a SOAC.
i really have no info on doing the conversion it was just a suggestion from one of the blokes i go 4wdin with.
does anyone have a rough estimated price on doing the conversion tho?

cheers for the help DD an pyro

I believe you end up with about a 5" or 6" lift after a SOA in a 60, so quite a bit of difference between a SOA and a 2.5" lift.

I'd be looking at the reason behind doing it, not because some guy suggested it. Big lifts look cool, but not necessarily the best solution, depending on what you're going for.
You may well get what you're after with some new springs, fat rubber and a locker or two, for a similar price.

Having said all this, SOA's do have a place and can be the right solution, but don't rush into it just because big lifts look cool. Make sure you know exactly what's involved and what you'll get out of it.

drive in - drive out about $3000 and up depending on options. that would assume no shackle reversal, re-using your springs and shocks, no or minimal wrap prevention on rear axle, minimal driveshaft mods/spacers, double arm steering. you probably won't get any change from $1000 for engineering.

without doubt the spring over will perform better of road, because you can soften the springs to allow better articulation and the extra clearance is always a bonus, but it's a lot to spend unless you're really serious about offroading.

you could, but ideally the plan is to flatten the springs a lot (remove leaves and/or re-set the springs) and aim for about a 4" lift. spring over should be more about improved articulation and clearance than outright lift.

again i agree with DD on this.

my first spring over 60 was on lifted springs, 2 inch body and 37s,
have a very tuff looks about it, but fark me was it big!!!!

the new one i will be re using the diffs from the first build, but using the standard springs so it will sit nowhere near as high, also no bodylift in this one.
