axle swap question
i have the stock axle on my 2wd 4.0 ranger and have been offered a posi 8.8 off an explorer with drums. will it direct bolt on? i was told his leafs are under and mine are over.. what then? will it bolt on and just lower the truck? will the truck be ok with the gears and extra inch on the axle

If you swap itas is you'll lower the rear end about 3in. If you want to keep your height you'll need to weld on new spring perches in the same position they are under the axle, just on top of the axle. I believe it's all bolt on from there.... You'll also have to weld on shock tabs, but since you'd be cutting the old ones off, you have to option to put them where you want. the expo 8.8 is a 31spline rear... Most likely a 3L73 axle meaning 3.73 gears with a Limited Slip carrier... Either that or with 3.50's or somethin like that...
What was the offer for on the 8.8?

No because you will just be lowering the truck more, because you are lifting the axle farther off the leaf spring. If you dont move the spring perches and mount it axle under.
Its not hard to swap the spring perches the longest part is cutting them off.
also you need to set your pinion angle when you move the spring perches

All answers posted are correct.
You MUST flip the spring perches onto the TOP of the tube, instead of the BOTTOM. If you dont, and you just bolt it up as-is, you'll lower your rear end about 5". Which is essencially a Flip Kit(converts the leafs from on top the axle to below). If you put a block in between the leaf and axle, you'll actually lower it even more if you dont put the perches on the top of the axle. So....if you put a 3" block there, you'll lower your truck about 8".
Weld new perches to the top of the tubes. Unless you wanna lower your truck.

Do you know anyone with a plasma cutter? if so have them cut your old mounts off. then smooth them out and weld them on at 12.75 inches from the backing plate at 45 degrees.
finally i beat you at something i already gave him that link. lol

the spring perch's are part of the u-bolt plate. there's no shock tabs on the axle.
I would get this:

Nothing hard about dealing with the axle man if you can fab parts for the shock tabs... Perches can be made several ways... Buy new ones, hole saw a piece of square tubing to go around the axle housing with hole to center it...
But yes, the fx4 lvl 2 31 spline is direct bolt in... that what I did a few months back.
