A few more details would help, but if you don't have the build sheet, you can check your glove box sticker for the rear end ID code. My 2500 has the 4.10 gear. I've pulled weights up to around 8500lbs so far, from campers to SUVs to skid steers and I haven't noticed the motor working much harder at all.
