does anybody know if a set of xj coils will support the rear of a k5? or another off the shelf coil spring that will work?
new question,3 or 4 link and why?

rear suspension-3 link or 4 link????

Well, they will "support" the rear end of a K5 but they will probably be way too soft.
The first thing you need to do is determine roughly what spring rate you need (pratically all coil spring manufacturers advertise their spring rates).
For a full bodied K5 you're probably looking for 300-400 lbs/in and the xj springs will be about half that.

I'd try f150 coils
I'll buy them and trade you for those 4" 56" springs

I used a set of 68 ElCamino rear springs in the rear of my 79 GMC pickup.
Work surprisingly well.

ok next question.3 or 4 link? and why
thanks

just run air shocks and save yourself the hassle
Cuz its a full bodied balzer that gets filled to the brim with camping gear so air shocks wouldn't do so well
on our trips i easly add 1000-1200 lbs to the rig it not more. air shocks dont really like it up here esp in the winter.

i run 2.0 air shocks.2.5s would be fine.
what ever is build it has to be strong-actualy has to be over built. when this rig heads in for our big trip it weighs close to 8k lbs and it is run hard in then spends 7-9 days of hard wheeling.so it has to withstand a lot of abuse.
airbags are a good idea if i could find a set with the right amount of trave,that or mount them on the arms in front of the axle.
i dont think air shocks will hold up with the weight and trying to keep them tuned with our temp swings would be a pain in the butt.one day it can be 50 the next it can be 80 plus.a friend tried them on his cj and they were a real pain to keep set right.

On most vehicles the front springs are considerably stiffer than the rear springs. This is because they generally have more weight up front (engine) and they need to be stiffer to resist the roll of the front caused by the tires turning (same idea as to why a lot of vehicles only have a swaybar in the front and not in the back also).
I will guess and say that F-150 front coils would be pretty stiff in the back of a Blazer.

If you can package a 4-link in the back (and it shouldn't be that tough) there isn't much reason to do a 3-link...
3-links get used up front a lot more due to space limitations and the complexity of adding steering linkage.
A properly designed 4-link can give you much better control over axle steer, and unlike a panhard bar setup you can always keep the axle perfectly centered under the truck.....even under extreme bump or droop travel. With a panhard bar (3-link) there is always going to be some amount of side-to-side movement of the axle as the suspension cycles.

the reason i dont like coils is they are not adjustable.lets say you get it all done take it out and your not happy with it.then you gotta try to find some coils that have the right spring rate.pita imo.plus you have to buy shocks and decent ones at that,by the time you do that then you have as much in it as i do in air shocks and i can change my spring rate on the trail if i wanted to just by adding oil.coilovers are nice because you can get mutiple spring rates and change them out as you please on the trail.you have to think you are going out for days at a time if you get a set of springs you arent happy with then your out even longer.just some food for thought.coil kinda go along with quarter eliptical it works but not the best option anymore
Personally I think air shocks would suck in you application.
what xj coils front rear lift what. I have used stock front TJ coils in the rear and they were soft. I doubt they would do much for carrying a load. For coils I would look at Grand Cherokee coils fronts. V=8 ones mostly. They should have the rate to carry a load
And yes 4 link as long as you can fit it. More adjustable.
Also have you thought about making the coils adjustable? I.E like the ACOS adjusters for Cherokees

4 link it and get a set oof FOA coilovers. You can also add a swaybar if needed.
and limiting straps and a suck down winch if you can afford it.i run a chain to keep mine from unloading.i run no bumpstops cause mine was set up that way but you might need thoose as well.you can set them up on your links if you want to
