Description
Upgrade or Replace. Whether you're rebuilding your 8.8" Traction-LOK rear or installing new gears, this kit from Ford Racing is what you need to do the job right. Make your differential perform even better than it did from the factory with this kit.

Used In Cobras & Shelbys. Don't choose inferior parts for your rebuild - this kit features the same carbon fiber clutch pack used in the Cobra and Shelby SVT Mustangs. These plates are more durable and are designed to handle more torque than the stock ones - lasting longer and transferring power better for both stock and modified 'Stangs.

Complete Kit For 31-Spline. This complete kit includes the clutch pack, shims, s-spring (31-spline), and an instruction sheet so you'll have everything you need.

Technical Note: 28 spline Mustangs will require use of a 28 spline S-spring (not included).

Good Rebuild

Was originally tempted to get a whole new posi, but this was a far cheaper alternative. Unless you really wanna upgrade to a 31 spline axle too I would recommend a rebuild with this kit.

  • Since you are rebuilding the Diff, it's the same as if you were just changing the fluid, so you need to use 75W140 Gear Oil and the Friction additive. People here on AM and the Forums swear by Royal Purple, so it's probably a good bet. For the additive, just go with the Ford Racing stuff. Both can be bought on AM.

  • You are fine with what you have but the Carbon Disks will out live the stock ones but what you have should give you many many miles of use.

    Works great!

    I purchased this Trac-lok kit with a set of 410 gears and bearing install kit. When I opened up my rear end to inspect the original 308 gears, bearings, and trac-lok I found that the original friction plates had broken tabs. I found them in the bottom of the housing all bent up from the gears. I was also getting one wheel burn outs due to the failing traction lok. I rebuilt my traction lok with this kit instead of paying $200 plus for another one. All together it took me about 15mins to rebuild the traction loc, although I did soak the friction plates for 24 hours prior to install. I could NOT use the S spring that came with the kit. It seemed thicker and I could not get it to compress enough to fit. Nevertheless I did reuse the original S spring and got it back in with a pair of 9" needle nose vise grips and a pair of 11" needle nose pliers. After you install the friction plates which come arranged in the proper order from American Muscle just slide in your side gears and while holding them in place put one pinion gear in at a time and rotate the side gears to pull the pinion gears into place. When you put the S spring in squeeze one half of the spring with the needle nose vise grips and lock them. Use your 11" needle nose pliers to reach through the traction loc carrier and squeeze the other half of the spring while pulling it into the carrier. When you reach through and grab the other half of the spring, don't grab both outside edges of the spring because you can't fit the spring plus your pliers through the carrier. Grab the spring in the center and on one edge of the spring. It will be hard to compress by hand but the idea is only to get the spring started between the gears. Once you have done this use a hammer and a small block of wood to tap the spring into place. Put some gear oil onto the spring and it will slide into place much easier. Again it only took me about 15 minutes to do. Getting a second person to tap on the spring while you pull on it with the pliers to guide it into place will make it much easier. Rebuilding one of these traction lok units is not hard to do. As long as your gears are ok in the unit I'd just rebuild it, but if you need to replace the gears as well it might be more beneficial to just buy another traction loc unit. Also after I installed my traction loc and 410 gears I did not get any noises. Soak your friction plates over night like I did if you have to but once it is all done you should not get any noise. If you do hear anything, such as a popping sound like someone has reported I'd pull my cover off and inspect the unit for broken tabs or chipped ring gear teeth.

    Carbon Disc Traction-LOK

    I had a Ring and Pinion shop professionally install these, along with Ford Racing 4:10 gears, and the car hooks very well, the spring that it comes with is for use with 31 spline axles though, so you need to reuse yours if you still have the stock 28 spline axles, or get the correct spring (smaller) from a Ford dealer

    Great upgrade!

    I removed my complete rear axle assembly to perform a gear swap and control arm upgrade. My 1990 GT has 78,000 miles, so I figured I should rebuild the differential while it was apart. The carbon disc kit is worth the extra money compared to the standard disc kit. I installed 3.73's and the new carbon discs are working great! About 150 miles on the new setup and i love it. Two even black marks every time!!!! The kit can packaged nicely and was easy to install. I do wish they would offer a kit that included a new 28 spline spring.

    Great Product

    Just like the description says \"If it is time to rebuild your rear dont cheap out\" this is true, I cheaped out when I got my gear installed and 4 months later I had problems in the rear end. I had clunking and howling noises, Installed new clutch paks and it runs great, shifts hard and smooth. Great Product and amazing quality

    Great update for warn Tlocks

    If you have the one wheel blues in your GT or Cobra, this fixes that. Installation is straight forward, for those who have rebuilt a rear before. Parts are great quality and everything is included for a solid rebuild. SOLID SOLID bite every time. Con: For DD apps, this kit WILL wear faster then the stock rebuild kit. How much faster depends on your driving. There are mixed reviews on this, and I haven't noticed any degradation in the 20,000 I have run on the kit.

    Nice kit

    Complete kit came with two seperate packages to keep disc in order. Used with a 4:10 gear swap, cheap insurance if you already have the gears out, go ahead and change your axle bearings while you are in there!!!

    Ford Racing LOK carbon disc rebuild kit

    Awesome product. And yes the S spring is for the 31 spline rear end. You can get the bigger spring in, but you pretty much have a spool type rear end.
