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. 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 JL engineers installed a very light weight, very thin wall (14 gauge), very body-integrated cage system.

To strengthen this lighter cage, the engineers produced an extremely hardened, odd shaped tubular design. In developing RH4x4's Cage Brace System, they broke virtually every drill bit in their 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 them. After fully year of research and development, they're proud to release their innovative design.

Installation

RH4x4 promised they'd innovate a no-weld design, and they've done it. Their Cage Brace System strengthens the weak/vulnerable points in the OEM JL cage plus adds functionality. Their System does require some special tools but does not require welding.

Drilling - every RH-90700 Cage Brace System includes a "Drill Bit Pack": 2 special hardened drill bits and a special "die grinding tree". Why 2 drill bits? Because odds are, you'll need 2. 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.
