Rock Hard 4x4 Rear Cage Brace System for Jeep Gladiator JT 2020+
$429.95
The RH4x4 Jeep bolt-in Sport Cage is the cornerstone of Rock Hard 4x4 products. Developed first for the Jeep Wrangler TJ and proven after years and years of trail use and abuse - the RH4x4 bolt-in Sports Cage has become one of the most popular safety upgrades in the Jeep aftermarket industry.

Features:
  • No Welding Required
  • Fits Factory Hard Top
  • 100% Made in USA
  • Lifetime Warranty
The Why - Factory Design Complications
The Wrangler JL almost didn't come to market with solid axles, and the Gladiator JT relied heavily on the JL design. Weight was a major factor in determining if the Wrangler would sacrifice off road capability for fuel mileage standards. In the end, and what we have today, is a Wrangler attempting to both satisfy regulations and maintain its heritage. To save weight, and save solid axles, the Jt engineers installed a very light weight, very thin wall (14 gauge), very body-integrated cage system.

The engineers produced an extremely hardened, odd shaped tubular design. In developing our Cage Brace System, we broke virtually every drill bit in our building. The tubing is unlike any material Jeep has ever used, certainly in the occupant safety realm. The shape requires a new way to install a Cage Brace System, and a back to the drawing board approach for us. After a fully year of research and development, we're proud to release our innovative design.

Installation
We promised we'd innovate a no-weld design, and we've done it. Our Cage Brace System strengthens the weak/vulnerable points in the OEM JT cage plus adds functionality. Our System does require some special tools, but does not require welding.

Drilling - The new factory cage material, while only 14 gauge, is hardened. It takes a very slow (300 RPM ideal, 500 RPM max) drill process and a special hardened cobalt drill bit to penetrate. Your big box store drill bits will not work. The die grinder tree will help you remove burs and finish out the holes. You aren't required to purchase, but may very well need, an additional Drill Bit Pack.

FAQ:

Why bolt-in?
There is nothing wrong with a race ready, NHRA/JeepSpeed/NASCAR/WRC/F1 approved, sonic tested, x-ray verified, high velocity impact tested, fully welded cage custom designed for your individual race vehicle. Except of course, the unaffordable price, massive vehicle disassembly, user unfriendly nature, and it goes without saying - non DIY install requirements. Those are just a few of the reasons we prefer our bolt-in method. Our RH4x4 bolt-in ready cage eliminates the headaches of a fully welded in cage for the wheeler from all walks of life yet provides an unbelievably strong, proven cage design.

Is any welding required?
No.

What finish is available?
Our cage systems ship in a raw, bare metal finish. This prevents potential shipping damage but more importantly allows you the freedom to select your own color locally. Continue a color theme into your cabin for a more unique, your Jeep look!

Where is this made?
This product, like all RH4x4 parts, was designed, developed, tested, manufactured, and if applicable, powder coated, and shipped in the USA. And we don't mean the 75% legal standard to be able to say Made in USA. We are 100% Made in the United States of America!

What is Rockhard 4x4?

The concept for Nebraska-based Rockhard 4x4 was started in the 1980s by Lewish Barth and his son, James. The two of them had been building off-road cages and bumpers for more than 20 years. By the 1990s, the duo was building so many cages for friends that transporting them became quite difficult. Welding the cage in was not something that everyone could do, and that’s when the bolt-in design was born. It was at that time that Rockhard 4x4 became home of the “do it yourself” cage installation. The brand has since evolved from DIY cage installation to a full-service manufacturing plant.

Why Choose Rockhard 4x4?

Rockhard 4x4 employs state-of-the-art CNC machining centers and combines that with laser cut precision and extraordinary craftsmanship. With this approach, Rockhard is able to take the bolt-in design of bumpers, cages, sliders, and skid plates to the next level. The company’s patented locking collar design sets itself apart in the aftermarket industry with its superior quality and proven strength. The locking collar connection is irrefutably strong and arguably stronger than other weld-in cages. While many competitors have tried to duplicate its design, none have come even close to the quality and workmanship offered by Rockhard 4x4. 

Rockhard 4x4 is known for producing exterior products that make off-roading in Jeeps a lot safer, smoother, and more comfortable. Its products are easy to install, provide paramount protection, exude aggressive styling, and won’t break the bank.

Quality Made in the USA

Rockhard 4x4 proudly manufactures all of its parts and systems in its 30,000 square-foot production facility in Nebraska. There is a certain level of quality and control you can only maintain when building products in the U.S. with a family running the show, and Rockhard proves just that. The experts at Rockhard 4x4 are off-road enthusiasts and wheelers themselves, so they know just how to manufacture armor that will instill confidence in the customer and provide strength-proven protection on America’s most demanding trails.
