93 K3500 14blt ff in a 2000 C2500?

[Lance Hohimer]

I currently have a 14blt SF 9.5 in my 2000 C2500. I have a 1993 K3500 with a 14blt FF. Can I put the 93 axle in the 2000 without any issues?
Thank you

So are you wanting to swap entire dif or ??

I want to put the full floating 14 bolt from the 1993 k3500 in my 2000 c2500 that has a semi floating 14 bolt. They are both 8 lug. For towing, I prefer a full float rear axle.

Center to center dimensions are different between 4x2 and 4x4. Short answer, no

What? Never heard of that.

Im not talking about a cab/chassis rear axle. Standard cab longbed

Measure spring pads to be sure, but I believe you'll just end up with a slighty wider wheel spacing. I have no idea how narrow the front is on a 2wd, but the 4x4s are very wide.....wider than the rear.

Yeah, the 2wd and 4x4 rear Wheel Mounting Surface (WMS) is different. I'm pretty sure that only applies to the 10 bolt (1500s,) however.

I believe the WMS for the 14 bolt is like 67.5", so assuming the '93 is thereabouts compared to the 2000, no problem. Swap it over. The 14 bolt 10.5" Full Float WMS are different for SRW, DRW, Cab & Chassis and Vans. There are no differences between 4x4 and 2wd, as far as I know. I believe the brakes are a bit better on the full float also, not sure on that.

Also good idea figure out ratios, just to make sure speedo is not off. On the 97-00 C/K3500 series, the 4.10s were standard, but earlier models went down to as low as 3.42s.

The 2wd trucks I've seen the front vs rear track width looks about the same, both wheels are kinda tucked in. But in the 4x4s the front is way popped out, but the rear looks about the same as the 2wd as @454cid pointed out. Some guys hate this look. I had not really paid attention until a few days ago looking at my 4x4.

Axle will bolt in. Driveshaft might need to be swapped, can't remember for the life of me if it needs to be lengthened or shortened. It's been 20 years since I did this swap. The widths for the 14 bolts are the same for 2wd/4wd, or get one from a van and will match the width for the front, not bolt in tho.
