Well I decided to finally get off my tail and do some measuring today to see what ways a LSD could be installed into the stock Lincoln LS differential carrier. There were two other viable options that Jason and I had thrown around.
1) Do a powertrax unit into the stock 8.0" diff case.
2) See if an 8.8" 28 spline differential would bolt into the LS 8.0" carrier while using the stock LS gears.
I know I had mentioned I planned to get to this and I finally did today. Tore the 8.8" down first. Took my measurements. Then it was time for the 8.0" LS diff teardown. Did that and took a few more detailed measurements. So far everything was a perfect match. Then I decided I had better unbolt the 8.0" ring gear and see how it measured up to the 8.8" ring gear bolt pattern. Same, 10 bolt pattern same OC measurement. I finished bolting the 8.0" LS ring gear onto the 8.8" differential and then bolted it all back into the LS carrier. Long story short... It was a dead match in every way.
I decided not to even measure for the Powertrax option as it will be the more expensive option of these two; though slightly more easy to install.
Now as some of you may know, we had already did the 8.8" full differential assembly swap in Jason's LS with a 8.8" LSD w/ 4.10 gears and a custom diff brace built by me. I wanted to discover if there was something a little more bolt in for those of you that just wanted an LSD but still stay with the 3.31 or 3.58 LS rear gears. This is it. So far I have only tested this on the Gen1 LS differential but have no reason to believe that it will not work with a Gen2 LS differential also. Once I do the differential swap in the springtime I will let you all know the official Gen2 results.
This will be a good mod for those of you planning to either to my turbo system, a roots supercharger like Quik or a nitrous system. No more one wheel wonders.
