No single upgrade can have as big of an offroad performance benefit as a locking differential. ARB is one of the originals and always our preferred option. The selectable design of the locker ensures easy, smooth operation under normal driving conditions, but maximum traction when needed. Their complete line offers fitment for nearly every application imaginable, and delivers 100% lock up on-demand. A relentless commitment to reliable design and the highest quality of component materials means that ARB Air Lockers are ready to handle the abuse you can throw out. From overland expedition builds to competition crawlers to desert and rock racing, ARB has logged the podium finishes and epic journeys to back up their pedigree. If that wasn't enough, all ARB air lockers are backed by a 5 year warranty. Even when time has passed beyond warranty, ARB Air Lockers are fully serviceable and rebuildable.
The Jeep Cherokee, TJ and YJ Wranglers are the defining 4x4's of their era. The Wrangler represents the 'true to it's roots' purpose built off-roader, and the Cherokee basically invented the modern SUV as we know it. Throughout their long production cycles, they all received different variations, and shared many parts. While all have a front Dana 30, there are subtle year and model differences; with rear ends, there are a few various models that were used depending on production date and trim specs, so it is always ideal to confirm which axle you have before ordering.
| Part # | Differential | Ratio | Spline Count | Notes |
|---|---|---|---|---|
| ARB-RD100 | D30 Front | 3.73 & Up | 27 | 1 |
| ARB-RD101 | D30 Front | 3.54 & Down | 27 | 1 |
| ARB-RD117 | D44 TJ Rubicon Front | 3.73 & Down | 30 | 3 |
| ARB-RD103 | D35 Rear | 2.73 - 3.31 | 27 | 3 |
| ARB-RD102 | D35 Rear | 3.54 & Up | 27 | 3 |
| ARB-RD93 | Chrysler 8.25" Rear | All | 29 | 2,3 |
| ARB-RD116 | D44 Rear | 3.92 & Up | 30 | 3 |
| ARB-RD117 | D44 TJ Rubicon Rear | 3.73 & Down | 30 | 3 |
| ARB-RD186 | AMC Model 20 Rear | 3.08 & Up | 29 | 4 |
| ARB-RD187 | AMC Model 20 Rear | 2.72 & Down | 29 | 4 |
Notes:
- 1 - Quadradrive traction control vehicles require non-Quadradrive axle shaft replacements for Air Locker installation
- 2 - Pre-1997 8.25" axle assemblies with 27 spline axle shafts will accept newer 29 spline shafts if RD93 is fitted.
- 3 - Newer OEM Dana 35, Dana 44 & Chrysler 8.25" ring gears may have 3/8", 7/16", or 1/2" ring gear bolts; Air Locker flange holes must be drilled or reamed larger to suit 7/16" or 1/2" bolts.
- 4 - Air Locker model RD186 has a floating thrust block to suit vehicles with tapered axles. The thrust block must not be used when swapping to full floating axles and some one-piece axle shaft conversions.
