Give your ride the upgrade it deserves with the DIRS-J Differential Integration and Reinforcement System! If your SRT 392 or Hellcat Durango is feeling a little wobbly, this system is here to turn that frown upside down—because who wants a car that behaves like a jellyfish?
Designed specifically for 2012 and newer SRT 392 and SRT Trackhawk Jeep Grand Cherokees and Durangos, the DIRS-J is your trusty sidekick for enhanced IRS operation and traction. The two-part design reinforces your differential case like a workout buddy with a strict diet plan: it won’t let you slack off! Part one locks into place using the lower main case bolts to give your differential the support it needs, while part two connects to the rear cross-member, integrating an OEM differential bushing for that extra kick of stability.
Crafted from American-made CNC machined T-6061 billet aluminum, the DIRS-J is as tough as a two-dollar steak but way more reliable. Featuring ARP and Grade 10.9 hardware, plus 304 stainless steel threaded inserts, this kit comes fully equipped with everything you need for a smooth installation, including Loctite to keep things tight. And don’t worry, we’ve added access to fill and drain plugs—because who likes playing hide-and-seek with their fluids?
Just a little heads-up: you’ll need to drill two holes in the rear cross-member for installation. It’s easier than making microwave popcorn—trust us!
So, whether you’re carving corners or just cruising to your favorite burger joint, the DIRS-J has your back. Gear up, hit the road, and let the good times roll!
