Upper control arms and 3/4 diff mounts are different from 6 lug to 8 lug.

diff can easily be overcome, upper control arm mounts can be spaced out to work. so yes its doable but the real question is do you want to go through all that?

Thanks for the feedback and info. I probably won’t be going through the trouble. I was hoping things might work, but if I have to Frankenstein it I’d rather not. Once I have the two trucks side by side for measurements and comparison I’ll post up if I find out something different.

Did you ever get those measurements?

Sorry, I don't have any thoughts on the lift... but where did you pick up your tb relocators? those are hard to find... especially in Canada

Trying to find this kit 7 inch fab tech c1500
call makesure they can get it first. ive been jerked around alot lately. sdtruckandspring are on my bad side rn, they said the fabtech dual shock kit was being shipped out last week and now i caleld to check up and its on back order. im kind of glad tho the fabtech kit mount on the upper control arm ears off the frame. so if u have a 2500 series, the control arm mounting locations are about 2.75" in difference from the k1500 to k2500 frames. i supposed u could try and weld a plate between them and drill the holes in the plate. procomp dual hoop kit for the 1500 series will never work out, just a aheads up for anyone who was wondering. the hoop itself just simply doesnt fit the 2500series.
i saw someone using what i think is a cognito dual hoop for 01-10 silverado's that looks like it should work out. im looking to this now and try to find answer. i also saw a guy on youtube sporting a dual hoop with fox shocks

Way to much work. The 1500 is about 4 to 6 inches smaller on the frame mounts for the upper control arms, compared to the 2500 and 3500 series.
