Should be 5/8 thread, i think 10-12 inches long and the axle tube should be 3 inch. The front has one longer u bolt though for one of the passenger side closest to the pumpkin.

The ubolt by the pumpkin is both longer and has a larger diameter than the other 3.

Also stock vs lift springs will affect the required length.

The one on the passenger side next to dif is definitely thicker diameter and I measured the width at 3.5, but just with tape measure. 9.5" for legs.
