Searched for inboard found no good leaf tech.
I have a j truck with pretty wide (far apart) rear leafs, it doesn't flex for sheeeot with my flatbed (no weight). I'm not running three add a leafs or anything stoopid but i was wondering if i moved them in closer together they would have to travel less distance to make the axle articulate. I have to keep it street able i'm almost 4 hrs from the con. What are the the disadvantages to doing this? Is it even a good ideah?

The disadvantage is loss of stability, but you get the same thing when you add flexy springs in the stock position. The advantage would be more flex for cheap. I think that about every 2" you inboard each spring, you will gain about 2" of total flex. But that's just kinda a ballpark figure with a lot of variables.

Some toy guys do this. I have never seen a write up on it, but I would look at frame outboards in the jeep Forum. It's the same process, just on the other side of the frame. Here's mine.

i had a J truck and never got a chance to do this: move them under the frame(instead if inside) and box the open sections while you are there. that will also net you 2+ in of lift allowing you to remove some leafs and/or run softer springs without loosing lift. and considering how wide as fawk the frame rails are apart stability should no be a problem

try a search on the toy PU forum. They've covered it. Its a fine idea, just don't go overboard and realize that there will be less resistance to body roll/stability.

did this on my fullsize chev, put em under the framerails, not only does the same amount of spring flex amount to more articulation but the wheels have more leverage on the springpack causing more articulation. under the framerails is best I think because it minimizes stress on the mounts and their leverage on the framerails

GM 63" 3/4 ton packs. let me know if ya need some more detailed pics frank.

mine are on the framerail, i was thinking inside of it.

if your frame is boxed, use the stock brackets from a truck that has outboarded springs, but run them backwards with some beefy gussets. just an:idea:

 

[AZFord4x4]

I agree with Fullsize, I almost tried that on mine, but the fuel tank got in the way. Should work really good. If you're already under the frame I wouldn't think the body roll & stuff would be any worse than us going from outside to under the frame.

Then maybe i should change to better spring packs before i move them in see if i cant just squeeze out a little more flex!
