If you have a Dana 44, 3.73 (or lower) open diff, or clutch pack based limited slip on your Jeep or Ford, this mechanical limited slip carrier (case) is a beautiful thing. Just like the clutch style limited slip, this carrier turns both wheels when you need it. Has no impact on street manners.

But the clutch packs in clutch style limited slip carriers only last 20 - 40 thousand miles (depending on how hard the vehicles is driven). A Truetrac will last the life of the vehicle.

Due to miss-information provided to me, and my lack of reading, I re-geared my Jeep XJ to 3.55. I have now re-geared again. This Truetrac was installed in my XJ in December 18' and has been driven approximately 1,000 - 1,500 miles.

Truetracs are Torsen carriers. The same style of differential carrier that is used in Military Humvees. They work like a clutch based limited slip, but are gear based. Plus, Truetracs do not require expensive synthetic oil nor friction modifier.

Are you wanting $400 for the true trac and 3.55 gears? Or just the true trac?
