Ford M4204F318C 8.8" Traction Lock, Silver

This is one of the best posse rear setup I have ever used

Received this 31-spline trac-lok carrier, and it's a genuine Ford part. Installed it without a hitch in an Explorer IRS housing, as part of a rear axle upgrade in a race car. I was pleasantly surprised to find it's already equipped with upgraded carbon friction discs. The performance upgrade carbon discs is normally available as Ford Performance upgrade kit M-4700-C, which by itself a $160. Awesome deal!

Awesome deal and quality FRPP parts.

I’ve had this lsd in my 05 grand marquis for little over a year now and I do frequent burnouts/ donuts with it. I’ve only had to replace the clutch packs once 8 months in but overall worth the 200$

For the price, this has to be one of the best upgrades that can be had for any Ford 8.8” differential. Works great in my ‘93 F-150.

I bought this for my 4x2 explorer with the 8.8 disk rear daily driver. Driving in the rain it would usually spin one tire since it had an open diff, so pulling out in traffic was sometimes sketchy. I professionally installed this, and it definitely helped give power to both wheels. I’ve had it in for a few months and will say though, sometimes I does still slip allowing one wheel to spin. I think it’s just a design flaw more so over actual product malfunction or whatever. Their are absolutely better designs out there but dollar for dollar, this is hard to beat.

The media could not be loaded. 1994 F150 4X4 4.9 ZF5 BW1356 3:55 8.8 33X10.5R15 KO2 the original 27yo LSD was shot out, clunky spider gears from lack of maintenance (wouldn’t hook up) the M4204F318c is a stock upgraded OEM replacement LSD, couldn’t hardly buy all the parts to rebuild properly for what this new unit cost..I’m going to use Dino oil with Ford additive change at .5K and again at 5k and run it.

Direct replacement to the open carrier. Since it’s a ford part the installation and set up was a breeze
