Rock Hard 4x4 is very proud to offer the original and most trusted bolt-in Rear Center Bar Sports Cage System for the Jeep Wrangler JK 2DR.

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.

Please Note: RH-1030-B Straight Across the Rear Bar is required to install RH-1030-C Rear Center Bars.

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.

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 RH-1030-B Straight Across the Rear 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
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.

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.

How secure is the RH4x4 locking collar?
If we didn't believe 100% in our collar design we wouldn't run it in our own rigs. It's patented design provides an unbreakable joint and you can feel confident will keep you and your passengers safe for a lifetime of trail use.

Why not replace the entire vehicle cage?
The answer is simple: crumple zones. The section of OEM cage that runs along the top of your doors from front to back has factory designed and DOT approved crumple zones that are designed to absorb impact during a roll over or collision. Without theses absorption sections your cage would "sheer" and not provide any protection. If we were to replace those with solid steel tubes, removing any absorption during roll over, your safety would be compromised. By retaining those crumple zones we can maximize their attributes and provide a more secure and safe system.

Is any welding required?
No. Our locking collars allow for a DIY no-weld, truly bolt-in install.

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 mount 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!
