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.
