    Technical Note. You will need to reuse your factory 8.8” gear set, or upgrade to a set of our 8.8" rear gears required for this Limited Slip Differential. No aftermarket gears are included. For normal driving conditions we recommend you use 75W 90 rear gear oil. This will give you the same oil weight as factory. For colder temps or race use try 75w 140.

    2 Top Rated Questions

    Will this spider gear set fit an 99 explorer 8.8 with a traction loc diff?

    • We can only guarantee fitment of these Spider Gears for a 03-04 Cobra, 05-14 V8, and 11-14 V6. Though, if you were to put this on another vehicle, it would have to have a 31 spline axle with an 8.8" gear set.

    Can I use this with 31 spline axles in my stock 28 spline carriage housing to convert to 31 spline rear end?

    • Hi, You will have change the entire differential instead of just using these Ford Limited Slip Differential Spider Gears - 31 Spline 8.8 in. to assure correct fitment.

      New Gears

      Changed my ratio from 4.10's to 3.55 to get better traction. They were easy to install. While I had everything apart, I changed out my clutch pack too. No issues thus far.

      Ford spider gears

      Glad I could just replace what I needed in my LSD. Easy install once you already have the diff out, originally I was replacing the gasket on the cover and noticed a few chips off the spider gears so out they went and in the new ones that easy

      Spider Gear Rebuild

      Once Again American Muscle parts do not Disappoint. Gears fit perfectly, operates smoothly, and corrected my noisy gears. Not to mention very reasonably priced.
