    I have heard that there are two different Dually axle lengths. One is about the same size as a stock Blazer axle and one is shorter. How much shorter is the short one compared to the normal K5 size one?

    Thanks

    I dont know about shorter but on a dually p/u is is alot wider than a stock axle. My 14 on my dump truck the outside duals are no wider than the cab of the truck. I'll measure it tonight unless someone beats me to a measurement. 74" for some reason rings a bell for a backing plate distance...but I might just be making that up.

    Does it matter if you put a dually 14 on a k5, i was under the impression that you couldnt put those on, just the single 14s.

    I think the difference is not 2 different dually axle widths, but rather the difference between "dually" and "dual wheel chassis cab". The dually trucks have a normal bed with the “flares” to cover the outer wheel. These trucks have a wider axle than “normal” trucks. The chassis cab trucks have a narrower rear axle so the outer tire is not sticking out.

    Soon: 4" lift, 40" tires, massive cutting, shorter wb and rear overhang.

    You can put pretty much anything anywhere with enough motivation and money. However, if you are talking about "bolt in" you are right. At a minimum, all 1 ton axles will require relocating the spring perches. And dually axles will require shortening to keep stock track widths.

    OK I dont know where I pulled that outher measurement from but backing plate to backing plate is only about 45" The inside duals almost touch the spring packs. HTH
