Anyone ever done this themselves? I'm wanting to get some 3.73's to put in my car, but I was wanting to install them myself...is this a bad idea? By the way, would 4.10 gears be too much for an automatic car? Thanks Jason

 

Installing gears should be left to pros. I would not recommend doing it yourself unless you have installed them before.

 

There was a thread just like this the other day. Do a search. Reasons why and why not were given.
