Crew Cab and Suburban Frames

[1774btcrew]

I don't have a build thread on my truck as I had most of it done before I found this website. I will have to look at the measurements but I have seen them posted elsewhere on this page as well. I am sure the 3/4 suburbans have a heavier frame but a heavier frame isn't the issue on strength when you are doing a 6bt conversion as much as is the heavier spindles and suspension for the 3/4 ton and one ton trucks(we have done several both 4bt and 6bt) . I would check 4btswaps.com for info on your 6bt swap if you haven't looked there yet. They have a ton of knowledgeable people and I really wish I had checked there before I built my truck as all of the problems I had someone on there had already been through and came up with a resolution that was similar or exactly the same as mine. It can be done with trial and error but it is much nicer just to talk to someone that has already done it!
