The 14 bolt axle tubes are a larger diameter. And while the brake mounting plates are the same bolt pattern, they are at a different angle than the 10 bolt ones. (turned 45 degrees or something close) So your calipers will be in a slightly different position but it doesn't make for a problem.

I was able to use everything from the 10 bolt brakes, even the lines. Just took some bending in a few spots.

about 3.3" I'm sure you could make the brackets wrap around there

I have a 93 1500 I plan on doing a six lug swap with a 14 bolt rear and I see you put the newer style brakes on yours, the question I have is besides finding the rear brakes off a newer truck is a spacer like you made the only other part I would need besides e-brake cables??? Any help would be great

could you have used an HD rear end, like in the duramax and put six lug axles in there? or is that what you did?

Correct, as long as you have the 99+ 1/2 ton rear disc brakes to put on there, all you will need to mount them onto the older 14 bolt axle ends are the spacers.

That is what I did, except that my 14 bolt came out of an older (88-98) 2500. I believe the newer trucks that come with the 14 bolt SF are already the correct length. I had to lengthen the axle tubes on mine in order for the 6 lug axles to fit. In those years if it had 8 lug axles, the rear end was about 3 inches narrower than the 6 lug 4WD versions.

I'm not sure if anyone makes 6 lug axles for the newer ones though.

Where would I be able to find a set of the spacer, or would I have to have a set made?

I made my own. I can make more, PM me for details.

Although because of variations in axle lengths, I'm not sure it would be a "one size fits all" type of deal. You would want to have your brake hardware gathered up and test fit it to determine the exact size you would need. That is, position your brake back plates and rotors at the ends of the axle shafts so that they are where they should be, and then measure the gap. Too short and your axle flange might rub, too long and your c-clips might not fit.

Digging up an old thread....


Are the spacers aluminum or steel? If they are steel, then I would just weld them to the tubes....
