Factory 4x4 Sunrader Leaf spring replacement

[granthum]

Recently came to acquire an '86 factory 4x4 Sunrader that is in serious need of a suspension refresh. I know the Old Man Emu CS010R is the go-to for folks around here for leaf spring replacement - but all of those threads seem to be talking about the 2WD models. I know the 4x4's sit a bit higher so my assumption would be that they need different springs, but truly, I am out of my depth here. would be grateful if anyone has any information!
 

same question in regards to shocks, too...

Should be able to find the factory specs and get a leaf pack from most anywhere that sells springs or a lift kit company. Also just measure the shocks and get some good aftermarket ones.

There is a “frame and axle shop” near me that custom builds leaf packs. They typically work on fire trucks and large rigs but they did my alignment on a previous toyota camper. 

 

I think if you load your sunrader up with a weight you’d expect it to be when loaded up and then go have it weighed, you’ll get a front and rear axle weight. Take that number with you to a shop that builds leafs as well as your old leaf pack and they may be able to custom build you a pack.
