    Is something like this possible?
    I know the biggest capacity of a suburban was a 3/4 Ton, and I have access to almost all of the components to convert mine to 3/4 Ton, but I was wondering if it's possible to convert a 2wd suburban into a 1 ton.
    Would 1 ton control arms and spindles and all fit on a suburban?
    Or would this require modifications?

    Thanks in advance

    I have heard that the frame differences between the 1/2 and 3/4 are negligible in some years. But I can’t imagine the 1 ton frame being similar to the 1/2 ton. Point i am trying to make Is upgrading the “suspension” to one ton isn’t going to increase payload more than the 3/4 ton. Frame is still the weak link here. Next you’ll be looking for a 1 ton truck frame and doing a body swap ( what is do If I needed it. Save a frame from being destroyed )

    What if I added addition support to the frame
    (tubular crossmembers, x bracing, boxing)?
    I have the means to make a 1/2 ton frame stronger than a 1 ton frame


    Edit: I'm not denying what you're saying.
    Might just as we be easier to swap frames, but if I'm going that far, I'll be on the hunt for a later mod 4x4 k30 frame to put under it

    Are the front 2WD cross members the same between 1/2t and 3/4t? I'm sure with your skills you can beef up the frame, but is it easier doing the frame swap?

    Arrowcraft used to sell the fender conversion, but I don't see it on their site anymore. There are other companies, but I don't know if standard truck fenders fit the Suburban around the rear doors.

    Probably easier to just swap frames, maybe while I'm at it just add an additional frame support in the middle or where I see fit.

    A crew cab k30 frame would be ideal

    Dad's got a 3/4 front he plasma cut off of a burb a long time ago.

    Are you thinking of going to a dually or keeping with single wheel?

    That makes it much easier then, because you really don't have to mess with the rear spring hangers and shock mounts unless you want to really mimic a 1 ton. A 14bolt FF from a 3/4 ton truck will bolt right in. As far as I know, the front suspension assembly is the same between a 3/4 and 1 ton, the 1 ton just uses s different steering knuckle, caliper and rotor.

    I've got a roller C30 frame out back if you would like to see some pictures for comparison.

    You're asking about a larger brake booster? Or larger rear drum and front disc

    If I had a 14b ff rear end I would convert to disc anyways, and front would have whatever size disc a 3/4 or 1 ton truck has.

    Well, no not a booster, just larger brakes overall like you'd have on a ton or hvy 3/4 ton. You've answered my question that you will address this upgrade also, since this likely is the most important aspect of hauling and towing.

    Oh of course!
    I planned on upgrading the brakes, that will come with a bigger rear axle and front suspension
