32 spline for m220 ?
Yes, the Mopar 68474060AC Rear Dana 44 Trac-Lok Assembly uses a 32-spline count designed specifically to fit the Dana M220 rear axle found in 2018–2024 Jeep Wrangler JL models.
Does this fit JT rear axles too?
Yes this is compatible to Wrangler JL and Gladiator JT applications. Thank you for the question.
Hi! Is this The original part or an upgraded part because of The problems some owners have experienced as described in this thread: https://www.jlwranglerforums.com/forum/threads/knock-under-driver-floor-board-while-decelerating.47505/#post-1215731
68401154AB was the original part that was causing the noise issues. In June Mopar changed this to 68474060AB. This is now for the new part 68474060AB
If I were to re-gear my axles to 4.56 would this product be compatible with that?
Yes, this will work with 4.56's
What gear ratio will this work with?
Current Dana 44 axles can accept all gear ratios. The factory ratios used with this carrier were 3.45 and 3.73.
