inboarded rear leafs to inside of frame??

[hackedup5]

OK, I've got a 77 J10, 4 1/2" front lift or so, and I'm putting a dana 60 in the rear.. mounting the springs under the frame will give me too much lift, and keeping them outboarded will create clearance issues, right? Will the rig be way to unstable if I swap the mounts to the inside of the frame so I can control the height? The 60 has no brakes now, but I will likely put drums on it as I need to keep a true functional e brake, and I'm building it on the cheap. My 60 is also 65" wms to wms if that matters.

Or....has anybody done inboarded springs under the frame with spring under and 63" chevy's, then it may be too low but will control axle wrap..
This is not a daily driver, just a trail rig with some street use.

Firstly.. we need pics... we like pics.

Keeping the springs outboarded will ONLY cause clearance issues if you change to disk brakes, at least that is my take on it. You are staying with drums so you will most likely have to cut off the perches and re-weld them on to the axle.

I have pics... but have not figured out how to post them yet, still looking into..
It makes it tougher to figure out clearances because I have too many loose ends on the truck:

-H1's still in recenter process, on my garage floor
-dana 60 doesn't have drums on it, and also on my garage floor

I do plan to set the H1's at 3 1/2 to 4" of B/S. It should not matter, but it is a LWB j10 and I am also taking 12" out of the w/b by moving spring hangers up at the same time.. I'll work on pics

I totally understand where you are at at this point in the buildup. At some point you just have to point your head at the water and jump in knowing that you can change it down the road if need be. One piece of advise I would offer up is that if you have the option at this point and still want your truck to do any "truck" duties consider this... moving the springs inside the frame will give your tires a CONSIDERABLE amount more leverage against the springs than they came with from the factory. If you can... I would get a higher rated spring rate the compensate for the increased leverage. If you stay with the stock spring it will be VERY flexy and you will at worst case have to run some bump stops.

perfect, thanks for the info on the pictures..and I would have goofed on the spring rate if you didn't mention that. I have stock rear leafs with a full length add a leaf I was going to pull, but if I do this I'll leave it and try it..Do you think it will sway to much to drive on the road, or just as much as your usual low spring rate/ no sway bar rig?

I don't know... as I have found before on this site everyone wants a different ride. I like a stiff ride but many like a soft ride.

Mine only sways when I have my quad in the back for example and it is still manageable. I just can't carve the canyons like I can when I am empty or near empty. The major difference is that you will be about 6" shorter than I am right now so it might not make a big difference.

I would at least give your current springs a go and see what you think. Depending on how wore out they are and the relocation they may work and they may not work to your liking.

Oh and nice truck... with brow I might add! :D

I appreciate your help on this..but somebody else has to have an opinion on this, the more the better.. COME ON PEOPLE!

I did this on my J10 that I shortend the frame on.Also did it for clearance with my 60 rear disc. I traded it to another member on here from dayton.Always did good for me.

There's a guy here in TX that built a dually tow truck using a c&c D70 axle and swapped his post mount spring hangers to the inside of the frame. Since the frame is wide on the JTruck you should have no problems and depending on how you move the shocks you should get better articulation. The alternative would be to go spring under frame and SUA.

Thanks guys, I'll bust out the grinder....

Here is mine. I put a Dana 70 in the rear, and to clear the massive brakes, I had to inboard the rear leafs and make them SUA. At the time I wasn't certain there would be enough room for disk brake caliper movement as the pads wear. I'm not thrilled about the loss of ground clearance, but I might leave it like this for a while.
