2500hd rear axle
I have a 2500hd 2wd with 6.0 and 4.10 rear. Looking to swap out rear end to 3.73 gear for fuel mileage. When looking at axles removed from trucks what codes should I be looking for and where on the housing? I believe mine is a 10.5 ring gear.

Re: 2500hd rear axle
You do have a 10.5" 14-bolt, GM used barcode stickers on GMT 800 truck axles too identify them at the plant, Are you sure they have Stamped codes on them?
4.10 to 3.73 isn't much of a change, With the heft of your truck...You Need 4.10's to tow the GCWR of your truck. If you don't tow or don't tow heavy.....You may have the wrong truck? |

Re: 2500hd rear axle
Hell, Clinebarger, if people only bought vehicles because they needed them for what they were intended for, we'd end up giving in to the brits and all driving cars. I got my Duramax to be my hotrod... Almost never tow with it.
