Axles under this platform
- Dana AdvanTEK M190 IFS
- Dana AdvanTEK M200
- Dana AdvanTEK M210 IFS with locker Carrier break: No single classic break to quote safely: JK Rubicon uses thick-cut ring gears on a 3.73-down carrier; JL M210/M220 carrier fit depends on factory locker vs open/LSD. Always order by axle + carrier part number.. JL M210 (front, 8.27-in ring) / M220 (rear, 8.66-in ring) are Advantek gears, not legacy D44 gears — parts do not interchange with TJ/JK D44. JK D44 max common 5.13 rear / 5.13 front.

JK D44 max common 5.13 rear / 5.13 front.
IFS front (no solid axle) — regears are front+rear AdvanTEK gear sets and are less commonly done than Jeep solid-axle regears. 4.70 is Sasquatch/manual-Badlands only from the factory.
Deciding? Run your exact combo in the regear comparison, then let the $39 Decision System turn it into a parts list, a budget and a shop-ready build sheet.
