🔧 Lock in your off-road dominance with ARB’s RD117 Differential!
The ARB RD117 Air Locking Differential is a high-performance, air-activated locker designed for Jeep Dana 44 axles with 30 spline ratios 3.73 and below. It converts your open differential into a fully locked or spool mode system, dramatically enhancing traction and control. Compatible with Jeep JK Rubicon models (part RD157), it supports full floating axles and requires separate air compressors, with ARB recommending their onboard systems. Known for robust build quality and ease of installation, this differential is a top-tier upgrade for serious off-road enthusiasts.

Great selectable locker for my dana 44 rubicon
This locker is a great build quality, and arb stands behind there products well. I got this to replace my factory rear locker that failed. I will be getting one for the front when that one fails too. It's pretty easy to install if you're mechanical enough.

Air leaked
Liked the idea .I already had a good air source. I installed it myself.and would recommend it only if your mechanicaly inclined. Spreading the axel is nessisary to seat the unit.I did the best I could.first attempt it started to leak air.seemed like other people had a similar problem.second attempt started to fail as well.it was getting a little agrivating and wished I tried to electronic one.third attempt I took off the rear axel plate to see again were it was leaking.it apeared to be the seal for the loker.before I went through all the work to disassemble it while the air was leaking I got a small piece of wood .removed the left bearing cap and tapeped the bearing. The leak stopped and so far no issues.
