Overview
The Alloy USA 352050 is a master ring and pinion installation kit for the Dana 30 JK axle, which the product title ties to the Jeep Wrangler JK (2007-2018). It gathers the small parts needed to rebuild a differential or install a ring and pinion set in one package.
The kit includes bearings, pinion seals, pinion shims, a crush sleeve, a pinion nut, ring gear bolts and gear marking compound, so each item does not have to be tracked down separately.
Key features
- Master kit with bearings
- Pinion seals and pinion shims included
- Crush sleeve and pinion nut included
- Ring gear bolts for ring gear installation
- Gear marking compound for tooth contact checks
Preparing for professional setup
Pinion depth, backlash and bearing preload all have to be set together, and that work is usually done by a shop with gear setup equipment. Before that appointment, clean the carrier and check the bearing bores for scoring. A clean housing makes the shim stack easier to read and reduces the chance of a poor contact pattern.
Keep the pinion nut and crush sleeve out of the setup until the shim stack is set. Pressing bearings and seals takes controlled force, so use a press or a proper driver rather than hammering. Eye protection should be worn during pressing, as the installation guidance advises.
- Clean the carrier before setup
- Check bearing bores for scoring
- Use a press rather than hammering bearings

Vehicle fitment
The Dana 30 JK axle is the basis for fit, and it corresponds to the Jeep Wrangler JK from 2007 to 2018. The JK chassis code is the only vehicle reference, so the years follow from that code.
It fits Wrangler JK models only, not the Wrangler TJ, LJ or JL generations. Verify year, model and trim against your vehicle before buying.
Installation notes
Gear sets like this usually need professional setup for pinion depth and backlash, and the crush sleeve is set during that process. Wear eye protection when pressing bearings and seals.
What’s included
Bearings, pinion seals, pinion shims, crush sleeve, pinion nut, ring gear bolts and marking compound.
Not included: The ring and pinion gear set is not part of the kit, so plan to use your own gear set.
