Hi guys.....
I am about to move my rear leafs to the inside of the frame, and I need to know if there are any tricks to doing it, and/or anything I need to look out for. Also, when you DO move them, is there any stability issues afterwords? Thanks in advance......

 

box the inner frame rails , and swap the hangers from left side to right side . i had a 55 on a shall we say teaked 74 1/2 ton frame . it had a cut down long bed and 1/2 ton fenders , and with them moved inside you had room for if i remember right { assuming the right offset wheels } 14 inches of rubber under it with a set of mini tubs . never got it finished though ........

 

I've already boxed and gusseted the frame. Should I run a thick walled spacer between the original frame, and the boxed rails on the inside?
Thanks for your help!

 

or drill and weld in flange nuts to bolt to for the brackets.

I would strongly recommend an anti sway bar for this setup.
(it will require bolts into the chassis too)

anti-sway bar is in the plan, and maybe I should box (inside to out) where the spring brackets go?? Thanks Sam.

 

yes

but I thought u said u already boxed the frame..

if u attempt to put them on the inside without boxing that area you lose a lot of the support the springs need..

Sam

 

the frame IS boxed...I was talking about making a boxed out area for where the spring mounting brackets go. Out side to inside, not front to back.

 

k. not sure I understand.. if u are moving them directly to the inside from the outside, then the boxing should be enough..

if u mean you want to move them FURTHER inside.. the yes, you'll have to make some additional mounting supports..

I don't know how much more inside u can go tho, before u end up with an unstable situation..

Lot of discussion on how...my question is why? To answer one of your original questions, yes there will be stability issues. Anytime you move a mounting, like a set of leaf springs, closer together you are increasing the lever arm for the applied force coming from the wheels. If you are planning on building some sort of "pro street" machine then I would go the same route that they do...4-bar with coils. And as Sam mentioned, you are going to need a beefy anti-sway bar setup.

 

Thanks for all of your help, guys. After doing some research, I went with a Heidts Mustang II front end, and a Heidts 4 link. Their warehouse is only about a half hour from my house, and they tossed in a bunch of free stuff. Thanks again!
