Rock Hard 4x4 is very proud to offer the original and most trusted bolt-in Harness Bar for the Jeep Wrangler JK 2DR.Adding a Harness Bar not only gives you a more rigid and stable cabin but also gives you the option to add safety harness belts to your factory or aftermarket seats. The RH4x4 Harness Bar for the Jeep Wrangler JK 2DR bolts to your factory sport cage hoop b-pillar using our patented collars.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 DesignProtected 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.StrengthSuccess 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.Ease of InstallationThanks 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.What comes in every kit:
