    Shock mounts, spring pads, and I believe the 1-tons had a brake drum of a slightly bigger size. I'm sure some 1-ton'ers will come forward on this.

    All the internal "strength" parts are all the same as far as I am aware. If you are wanting to swap a 14bff into a K5 then the 3/4 ton makes for an easier swap. If you are towing the 1 ton might be a better choice due to the bigger brakes.

    Bigger brakes seem to be about it. Mine are huge compared to the 3/4 which are comparable to 1/2 ton brakes. Yeah it works really well.

    Yep, easier swap. On 3/4 ton axles you don't have to relocate the spring plates. A 1 ton has to have the spring plates cut off the factory plates, and weld a new set on in the proper positions. You can get the 3/4 ton axle, and bolt it in in place of the 1/2 ton axle. From what I understand you do have to move the shock mounts on the axle, possibly modify the E-brake cable to work, and get a Napa #447 hybrid u-joint. Along with 8 lug wheels.

    Easier because you don't need to mess with spring perches or shock mounts if you use a 3/4 ton.

    Hmm, do the shock mounts require moving? I guess I was wrong on that.? I thought the 3/4 was "complete bolt in" to a K5. In this case "complete bolt in" meaning uses common tools and no welding/fab required. Dealing with mismatches in the joint, wheels, and e-brake cables are a given but still considered "bolt in".

    I thought the 3/4 ton shock mounts lined up? I don't know cus I cut mine off before I even swapped it in.

    3/4 ton is a bolt up but the e brake cables might not work. If it is a Burben 3/4 ton it is a direct swap including e brakes. 1 ton has bigger brakes and depending on years the e brake will bolt in but you need to move spring perchs and shock mounts. The total width is the same between the 2.

    I am not sure if they have to be moved or not. I thought I remember someone saying they did need to be moved. But I don't know. I hope I am wrong. I just got a 3/4 ton 14bff, and that will save me a little $ if I don't have to move them.

    What year Suburban? On the 80 whatever when they swapped the brake line set up it probably will but on the older style(one line per side, instead of both up the drivers side) I have to modify mine to get the 78 burb 14FF to fit the Blazer.

    not money but lots of grinding. I had to move spring and shock perches/mounts but that only took 3 hours, i was puttin in a rear cv anyway so i would have to cut them off anyway. They were beefy though

    My problem is I don't have access to a welder to weld in new mounts. Ok, thats a lie, I do have access to a welder, but my buddy can't weld for crap, and I have not learned how yet. So it would end up costing me some $ to get the new mounts in.

    Comparable to 1/2 ton brakes? Not even close!! The drums on my swapped in 3/4 ton 14 bolt are two inches larger in diameter than the 10 bolt drums that were on there before. They also wider, and just plain a lot bigger!
