I want to replace my stock 3.55's with 4.10's. For those of you that have completed this upgrade, how much did it cost?
Thanks.

 

I haven't done it yet, but my dealer quoted me $450 to $500. Good Luck !

max,

Wow! Since I posted, I called my dealer and they quoted me $800/rear and $1200/front for a total of $2000! I called several dealers and some independent shops and the range was from $2,000-$2,500! You will have a wicked ride after you get your 4.10's in with the 5.4!

That seems very high. Yes, 4.10s are awesome. I'm waiting to hear how the speedo issue is resolved for 2000 models. In the Ford Performance Catalog the rears gears are $199 and the LH fronts are $239. I've seen many posts where people paid $450 and up, and some for both sets for $1000-$1400.
