So should the gear ratio be stamped on the diff?

 

To answer a few questions in this thread...

Typical price for gears + install is between $400 and $500 an axle.

Dodge has an assembly plant in Mexico that builds trucks for the American market. They've had one there for decades

4:10s were standard in Off-road package Rams. Optional on everything else.

Rear discs were on the 01 1/2 tons and 01 & 02 3/4 ton and 1-ton trucks. Stick with the drums and upgrade the wheel cylinders...much cheaper

You will notice a performance loss going from 285s to 35s without re-gearing. Not so much on the highway, but definitely from a stop.

Last but not least, rear axles are all the same....doesn't matter if it's 2x4 or 4x4

 

Well burning rom swooping in like a screaming eagle and answering some questions, thanks. I try every night to go to sleep knowing more than i did when i woke up. I can now say that I have accomplished that at 11:53pm.

 

that would explain why my buddies 01 sport non offroad has stamped 4.10 diffs...

and as far as i know there were absolutly no 1/2 tons with disc brakes.. they made the switch to rear discs in 01 and 02 with the 3/4 and 1 ton trucks.. but no 1/2 tons came off the factory line with disc brakes.. mines a 01 and it had drums, and everyone else i know on here with 01's and other forums with 01's have drums..

to be exact.. 2001.5: All 2500, 3500 Four wheel Disc Brake - built after Jan 1, 2001
