New Upgrades Available for the JL Wrangler

As manufacturers of the world’s premier selectable lockers, ARB recently issued the following press release, regarding new parts available for the 2018 Jeep Wrangler (JL) Sport:

ARB maintains a strong presence in the off roading industry with its proactive approach in R&D. Supporting accessories alongside new vehicle releases is key to staying ahead of the game. Our drivetrain engineers have assessed Jeep’s new Wrangler JL Sport and are proud to announce the release of Air Locker applications for both the front and rear axles.

Replacing the JK, Jeep has built on the Wrangler’s legendary history with their most capable vehicle to date, while maintaining its heritage with touches such as a seven-slot grille, iconic round headlights and open air models. To complement these unique touches, Jeep has upgraded the off road ability and central to this is next-generation Dana axles. To further enhance the JL Sport’s capability off road, ARB is happy to release front and rear locker applications.

  • For the rear axle M200 application, RD244 was newly developed.
