Start with your local Ford dealer to get a high end price. Then, check with local speed and performance shops to get better pricing and advice on different gearing options. You don't have to have either 3.73 or 4.10 in the Trac. Tell them what size tires you want to run and if you are interested in performance or economy. Then, you can select a gear ratio that is right for your tire size and performance needs.

You can go junkyard diving and buy a whole new rear axle...that'd be the easiest. Only have to remove the driveshaft, the leafs, the brake lines and really...you're done.
A few places see upgraded gears that you have to install yourself. For soem reason, all the names are escaping me at the moment.
Do you plan on doing this yourself? Because gear swaps can get expensive, fast. A member wanted to upgrade his from 3.73 open to Ford 4.10 LS, was quoted around $1200.

Thanks for the quick responses. I was going to pay to have this done but couldn't see spending more than around 500 or 600 for it all. I sent this out to get an idea on the price. I think I'll hold off on this idea for a while.... Thanks again

keep in mind if you have a 4wd, you need to change both front and rear... the whole axle swap would be the easiest. IMHO

howdy,,
I do belive that powrlok makes an upgraded LS/Locker for 8.8 with LS carriers,,
I am more familar with the Dana 44 as apposed to the Ford 8.8,, because I have a couple of IH Scouts I am always beating,, but I do beleive the situation is the same. If you have a Dif with a factory LS in it,, then you are kind of limited on which lockers you can put in with having to change out the carrier.
Lets say you want a luch box style locker like and Aussie locker,, nice locker for under $250,, and a real locker,, which is night and day over a limited slip or 'clutch' type locker. It will not fit in an LS carrier, it can only be enstalled in an "open"carrier. The open carries are only like $60 new,, but you will have to set up the gears again. If you get a Detriot, ARB, OX, and so they are built around their own carriers and seting up the gears is implied.
You might see if you can find a powr lok for an 8.8 LS that does not need a gear set up. It will be a much tighter lock up than the factory double dog clutch. I have an 01 ST with 4x4 LS and 4.10s.. and so far the LS has worked very will..
Good luck brother

I had my 4.10s swapped out for 5.13s & it cost me around 800.00 for everything.
BTW if anyones interested in some good used gears I have the set of 4.10s cheap.

Griff,
What year and 4wd, 2wd ??? And do you have a Limited slip now or not???
If your under 2002 and have drum brakes, you better off getting a rear from the junk yard from and 03 and up and get the 4:10 and the disk brakes.....
If you have a limited slip 3:73 now all you need is a new r/p and installation kit. About 300 or so in parts and labor......

For 2003 the 3:73 axle with limited-slip was optional on the XLS & the XLT, the 4:10 axle with limited-slip was optional on the XLT & the XLT Premium with either 4x2 or 4x4.
