Product Resources
Features & Product Details
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.
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.

REVIEWS & CUSTOMER MEDIA
TAKE YOUR TIME. I got this system for front and rear for added protection after seeing a few rollovers. I love the finished product. I installed it all myself, first time doing rivnuts. Make sure to mock it up several times before drilling anything. The rear is very tricky to get the rear bar to sit just right on the frame. Make sure to follow the instruction to use the tap on all of the threaded parts EVERY TIME you install and reinstall a bolt. You will strip them if you don't. Just go slow, tap and wd40 each time. Once I drilled all the holes and installed rivnuts I was worried but it all fit perfectly, didn't have to adjust anything. Sent it out for powder coating and it all installed right up. I got it powder coated a dark gray/black to match interior and it looks amazing. It looks like it is stock and blends right in. I got the molle bag and that helps hide the welds and make it look even more stock.
