So what would it take to merry my truck to this 2.5 Ton Rockwell Axles on a straight chassis with leaf springs with all steering components? I mean the body itself,the tranny,the motor.Everything? And yes i can do all the fab work needed.Cutting/welding,grinding and so on. Also how much besides what i would spend on the Rockwells would i expect to shell out for all what i would need? Give her a look Rockwells Or its not even worth it?
if you are using that chassis, i dont think it would be all the difficult, would just need to make custom body mounts, motor mounts etc. seem like it would be a fairly easy concept, but i would do it to an older truck rather than yours
I'm with Nick, custom body mounts, engine mounts, and transmission mount and you should be about set. The only think I think would be the steering geometry might change and you could fix that too.
check the wheelbase length as well. if your those wont match your current wheelbase measurement, you have a bigger headache: either have to chop your truck shorter, or find a way to make it longer.
First i agree with every one else on do it to something older, but i think it would be easier to put the axle under your truck's frame. Then it would be like doing a SAS to your truck, You already have all the motor, tranny, and body mounts there.
