Please Note: Test fitting is required prior to powder coating / paint. While we make every effort to insure the highest quality parts arrive for install, Rock Hard 4x4 cannot be held liable for any coating expenses on cage components.
The RH4x4 Jeep bolt-in Sport Cage is the cornerstone of Rock Hard 4x4 parts. 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.
Our proprietary locking collars are arguably the safest and most secure way to not only strengthen your Jeep's cabin but also provide you and your passengers the peace and mind that comes with a premium cage system. No other bolt-in cage comes close to the fitment, quality, and durability of our system.
Patented Design
Protected by Patent US6908107 and used in all our cage systems, our locking collars are the foundation for our Ultimate Sports Cage upgrade. Magazine editors, trail guides, wheelers from across the world, and even competitors have turned to our bolt-in cage for over a decade for their own vehicles. The strength our collars provide is inherent in how they couple our cage components together.
Our patent not only protects RH4x4 from domestic and overseas "knock-offs" but also gives you the peace of mind knowing we stand 100% behind our product. Our registration gives you the exact definition and purpose for our cage components. We encourage you to read our patent registration and see just how much thought, time, and care was put into our system. Why has no other manufacturer patented their cage system? Either its a copy of another system, or they simply don't feel confident enough in their development. Don't purchase a component that was simply meant to compete in a market, purchase a product that was born to create a market.
Strength
Success stories of our bolt-in Sports Cage are not hard to find. Virtually every Jeep forum online contains detailed user-installed threads and photos of how DIY'ers were able to not only install our cage but enjoy it run after run. This is THE Jeep cage.

With our patent secured over a decade ago we began production on our cages. Each collar, cap, and tube component in our system is produced in house. This gives us total control over manufacturing to ensure that once a system leaves our facility and gets installed in your Jeep, we know it will continue to uphold our sterling reputation.
Our locking collars and caps are solid 1/2" thick CNC machined steel and produced in house. Each cap is secured to it's matching collar with six 5/16" x 1" grade 8 socket head cap screws. Once a cap is secured to it's collar it becomes a solid, unbreakable joint. This means assembly and disassembly is achieved without welding or cutting which could potentially damage your Jeep's interior or expensive cage powder coat/paint finish.
Our tubing, which connects our collars, is made from extremely strong 1 3/4" .120 wall steel tube and are precisely cut and fit for your Jeep model. There is no guess work when it comes to which component installs where. Each collar is expertly hand welded to it's matching tube section and can only install one way.
Our overhead streamer that connects our upper/across windshield bar to your OEM sound bar has been plated with 14 gauge steel to provide both a clean look and also give you an out of the way, convenient accessory mounting location. Mount your CB, flashlight, safety gear, or any other accessory you want to be able to reach easily and quickly.
Ease of Installation
Thanks in part to our collar design there is no need to ship you a completely welded together cage system that requires major vehicle disassembly. Our cage ships in a complete package that includes the individual components that assemble into our sports cage. Simply powder coat or paint the color of your choice and use our easy to follow instructions to complete your own install.
The secret behind our system's ease of install is precise fitment. From our dash bar that retains use of your tweeter speakers to our overhead streamer, each component is an exact fit for your model Jeep. Included in our front cage a-pillar uprights are welded on grab handles angled to not only make it easier to climb in and out of your Jeep, but also allow you to retain your OEM sun visors.
Components
RH4x4 Sport Cages are very recognizable for two major reasons: owners bragging about cage and consistent, clean, functional design. What makes up a RH4x4 cage is what makes them so strong.
Overhead Cage Streamer with welded on plate steel mounting plate. This cage section connects with twin collars/caps our upper across windshield bar to your OEM sound bar via secure, heavy duty hardware.
Over and Across Windshield Cage Section - when coupled with Overhead Cage Streamer forms the "t-section". This connects to your OEM cage and crumple zones for safety and rigidity.
Dash Bar Cage Section - connects to the mirror image a-pillar uprights. Couples with matching collar caps and not only adds rigidity to your cage but also gives you limitless mounting points for accessories like cameras and GPS systems with our RH-1021 1 3/4" Accessory Mounting Bracket. Our dash bar is angled to provide clearance for your factory tweeters and maximum clearance for aftermarket dash accessories like the 2007-2010 Daystar cargo tray. Your view is not obstructed by dash bar.
A-pillar Upright Cage Sections - mirror image cage components that tie in the steel structure behind your dash, the extreme rigidity of your door posts, and your upper windshield frame. Each door upright includes a hand welded heavy duty grab handle in exactly the right position.
Windshield Tie-In Mounts to A-pillar Uprights - your windshield is an integral part of your cage system, which is why the factory and Rock Hard 4x4 have chosen to keep them connected. In fact, we bolt our a-pillar upright directly to one another. In the unfortunate event of a roll over, you don't want your windshield to no longer have any upper support beyond the lower mounting plate. Flapping metal and glass out front of your rig can be extremely dangerous. A competing cage removes that upper support making your cabin a very dangerous place to be in a rollover. The Rock Hard 4x4 cage provides proper windshield frame support by mounting our a-pillar uprights to existing brackets. This keeps your windshield frame in place during a rollover and maintains your factory crumple zones.
Tweeter Speaker Compatibility - You do not have to relocate, disconnect, or adjust your tweeter during installation. Our dash bar does not require you touch your tweeter speaker at all.
