Ok so I was thinking instead of figuring out a 4 link setup would it be possible to run a set of half ton springs on our trucks and of course airbags. Are the half ton springs the same length has ours or are they shorter. The only thing the springs would be used for is centering the axle thats it

6" deavers are half ton springs IIRC

just my .02 but wouldn't taking out the overload and a spring or two be easier?

well a 1/2ton's springs are only two springs pack and they aren't as think as ours either
