Front reverse gearing basics
A front reverse ring and pinion mounts the gears in a reverse orientation from a standard front set, so the pinion sits on the opposite side of the carrier. That layout is used on the Dana 30 JK front axle to suit the front driveline geometry. Make sure the axle is a reverse design before buying, since a standard set will not mesh.
Front gearing changes add load to the front axle shafts, joints and differential bearings. A 5.13 ratio is a noticeable change from factory gearing, so check the front driveline for wear while the carrier is out. Pay attention to steering feel and any new noise, and address rough steering or clicking CV joints promptly.
- Confirm the axle is a Dana 30 JK front before ordering
- Check front differential fluid after the first drive
- Inspect front axle seals and CV boots at the same time
