post your 67-72 4x4

[outfield]

The Rancho Shock Part Numbers on your Invoice 9001 / 9112 are the 4 inch lift shocks for 1973 to 1987 Trucks, the front shocks are the same back to 1969 I believe, I believe the rear were different though, but the 9112's are so long, they probably fit anyway.
The invoice says SUP HD springs 01-255, these are Super Lift 6 Inch Lift front Springs for 1967 to 1972 Chevys. So the front shock may be a tad short...
I see an add a leaf for the rear. We would sell a 4 inch block kit, and add a leaf kit when lifting Chevys 6 inches, I don't see a 4 inch block kit though.
There is a Rancho steering stabilizer and bracket listed also.

Hope this helps.

still waiting for reply to my email inquiry to Tuff Country regarding old p/n translation on the lift specs..

but either way, there was $1800 of '99 money put under there.. shocks are about all needs replacement I suspect..

maybe one of y'all know more about this? anyone know old numbers? I crapped out on google..

and yes it was known to all previous owners and titled as a '71 although we know different

thank you very much for your thoughtful and informative reply!

I guess I'd have to call tuff country, sent a courteous email and two follow ups a week apart.. seemed reasonable..

I'll take some pictures underneath and bounce that off your info to see where it's at..

previous owners may have made changes since that invoiced work but I don't recall seeing any blocks under there..

not my area of expertise by any means so all info much appreciated, thanks again!

By the look of the stance of your Burb I would say is has a 6 inch lift. The front must be all springs, which I see it is. The rear can be all springs, or blocks and springs as needed. Definitely take a picture or two of the rear set up and we can see what you have. An add a leaf is uaually a sorter thick leaf found near the bottom of the spring pack. All the stock leaves will be the same thickness, except the bottom overload spring.

All the add a leaf kits I buy are a full length minus about 1" each end than the top leaf, the super thick short leaf is an overload, but some companys "try" to seel them as an add a leaf but don't actually lift the truck any more than the thickness of the leaf cause the ends of it doesn't touch the spring above it.
Someone may have had a 4" block they used with the add a leaf in the rear. I keep a bunch of different heights in my shop. Guess you have to look.

How are the road manners with the 54" fronts? Are you running a sway bar? Awesome truck BTW!

Not sure how it is with the 54s as I just finished truck. I have king shocks on it with compression adjusters and a Currie anti rock sway bar on the rear of the truck. I may add a anti rock on the front if it is really soft but the compression adjusters on the king shocks should help. To add the Currie sway bar to the front is super tight because the cross over steering uses a 2 wd steering box which puts the pitman arm opposite of the 4wd box. I will have to cut the sway bar arms and add bends to clear.
