Cost to change rear gear ratio.
 
I called my local Dodge dealer to get an estimate to change the gear ratio from 3.55 to 3.92 in my 2010 1500 4X4 SLT Crew Cab. I about dropped the phone...... $1,000-labor & $800-parts. What do you guys think?

Damn that's a lot of money. Could someone else explain why it might be worth to do this because I just don't know about gears and ratios?

I'm going to be pulling a 5th wheel trailer that is about 6600 lbs. dry. I have the towing package on my truck but it has 3.55 rear end gears. The change to 3.92 gears would keep the truck more in the power range towing and would be easier on the drive train. Down side is it would more than likely use more fuel. I am going to try towing with what I have first as the cost to change gears makes me ill!

Wow! that is crazy. I know Jeep guys change their gears all the time, so it shouldn't be that difficult to do, but not sure if that would effect something with the computer...Not sure on these new fangled machines.

I would think you might be better off going with a set of 4.10's . You haven't changed the gearing span enough for me to spend that kind of money and not see a substantial increase in performance . Especially if you change tire size .

I agree 100%!!! 3.55 to 3.92 isn't much of a change at all.

As far as cost, the 4WD is what's making it so expensive,,, twice as much labor and parts as a 2WD,,,

Any idea how much top end will be cut off with a 4.10 Rear? Want to get her quicker off the lane but don't want to lose to much top end.

If that 1800.00 is both front and rear, its a great price. Don't forget with a 4x4 you have to change both ends.
