thanks man, now what all would i have to do to get this to work. would i need new axles and/or new gears or would my gears and axels work fine

brianm · November 11th, 2007, 03:37 AM

don't waste money on axles, unless your on slicks. your old gears are fire just get new bearings, its a good idea.

You already have a posi, or a limited slip differential.

+1! The eaton LSD clutches will wear out and you'll be replacing them. Now I have heard some people say the true tracs are a little noisey and others say they are quiet as stock, but the true trac is your best bet. If you plan on running slicks or drag radials and plan on hard launches then I would step up to the 31 spline axles and true trac diff. If not they do make a 28 spline true trac. It's up to you and your driving style. I'm going with a supercharger down the road for sure and drag radials so I am building my rear end up...axles, diff, 3.73s, girdle, and a complete rear end rebuild kit. If you want a good price with free shipping on a true trac diff checkout this page.

i like the tru track. Now when going to install it, what all will i have to do cause i just got my 4.10 frpp gears installed and dont want to loose those.

Black Bullitt · November 12th, 2007, 01:12 PM

You won't lose you gears from installing a diff. Just make sure that you either oder the 28 or 31 spline diff depending on if you are keeping the stock axles or upgrading to the 31 spline axles. If you purchase a master kit it should have everything you need.

01dutchGT · November 12th, 2007, 01:18 PM

Im going to go with the 28 spline and what all does the master kit come with and is this something i could install myself or should i let a shop do it.

Black Bullitt · November 12th, 2007, 01:33 PM

Unless you know how to do it and have the right tools have a shop do it. If you have a shop do it they might have the right kit to install everything so you don't have to worry about it.

01dutchGT · November 12th, 2007, 01:34 PM

ok cool thanks man

Black Bullitt · November 12th, 2007, 01:37 PM

Not problem. If you plan on going FI at all or doing hard launches I would suggest going with a 31 spline setup and doing it right the first time. I'm not telling you how to mod your mustang I'm just looking out for your future interests that may come along.
