Front reverse basics
A front reverse set is built for the rotation direction used in a Dana 44 front axle, so it is not interchangeable with a standard gear set. Confirm the axle is a front unit before buying, because the wrong rotation can lead to poor mesh and noise.
The 5.13 ratio gives more pulling power from a stop and raises engine speed at highway pace, which can add some noise and heat. Tire size changes the effective gearing too, so consider tires and typical load together. Shops often check the gear contact pattern with marking compound before final assembly.
Carrier bearings, pinion bearings, and the pinion seal are commonly replaced with new gears, since they were set for the old pattern. Inspect the carrier for wear or cracks before reuse. After a break-in period, check the gear oil for metal particles, which can point to early wear.

This 5.13 front reverse set fits the front Dana 44 axle and is not tied to one vehicle. Confirm the carrier rating and axle housing before installing.
Installation notes
Because a 5.13 ratio changes the axle’s gearing noticeably, have the gears set up by a qualified shop and allow a break-in period.
