“Updated 2011-up Ram 9.25 ZF limited slip posi 31 spline differential carrier.  Our one-of-a-kind design updates the OE design by adding a belleville spring washer to the clutch pack, allowing the differential to function like a true limited slip posi.  The OE design does not use springs, which gives poor limited slip performance, functioning more like an open, non-limited slip differential.”
