Dana Spicer 10010521 is a UD44 JK-Front axle assembly: a Dana 44 front axle with a 4.88 gear ratio and an electronic locker, listed for the 2007-17 Wrangler and 2018 Wrangler JK. It ships with the mounting bracket and without brakes, and it has chromoly axle shafts with 1350 series U-joints, 30 inner and 32 outer splines, and a companion flange end yoke for a 1310 series driveshaft U-joint.
It is built as a direct bolt-in swap that lets the original wheel ends be reused. Thickened axle tubes and redesigned heavier brackets resist bending off-road, and the locker is selectable electronically (its wiring harness is sold separately).
