View Full Version : Gear Swap
12-05-2002, 10:56 PM
I have a 2001 2500 auto with 3.55 gears and am towing just under 10K. I am seriously considering going to 4.10's because of the fact that I live in British Columbia and can't drive more than fifty miles without having to climb a mountain. Since I have had gauges installed and seen the temps I can get to as soon as the TC unlocks, I have serious doubts as to how long the transmission is going to last unless i do something. Has anyone else made this swap and how do they feel since doing it?

I have a 95 with 4:10 on it with only 100K miles would you be interested in trading. Have a 5 speed and would like to be able to run down the road a little faster.<br>

Wilber, a good friend of mine swaped his 4x4 out to the 4.10's and is very pleased with the results.

Someone correct me if Im wrong but I do believe the diffs are the same in both a 95 and a 2001. Mine does have a limited slip does yours?<br><br>Trickytrae
The rear should be a dana 80 not sure about the front but I had a 2 wheel 95 duallie and an 01 4x4 duallie and a 98 4x4 dualie and the rear axles have all been the same. I would bem willing to bet the fronts are the same. An axle swap would be a lot cheaper than replacing gears.

The front ends are Dana 60's. The rears on duallies are Dana 80s. Most 3/4 tons have Dana 70 rears. But, I understand that some have been fitted with Dana 80's. Mine is listed right under the hood. Open the hood and look up.<br>See ya! ::)

Maybe I can help clarify things about the rear axle. All the 3500's have the Dana 80, the 2500 manual's (5 & 6spd.) have the Dana 80, and the 2500 auto's have the Dana 70. I'm fairly certain they all have the Dana 60 front axle.

Trickytrae<br><br>Thanks for the offer but my truck only has 12,000 miles on it, so I will go for brand new gears. It is a 2WD and has a Dana 70. Found the info on a sticker on the inside of the glove box door.
