Rock Hard 4x4 Ultimate Sports Cage - Bolt-In Convenience

Installing the Ultimate Sports Cage from Rock Hard 4x4 Parts

Christian LeePhotographer, Writer

Rock Hard 4x4 Parts has been in the bolt-in sports 'cage and bumper business for more than 20 years. In that time it has perfected the bolt-in sports 'cage design and applied it to almost every Jeep model available. The Ultimate Sports Cage kit offers an easy bolt-in installation that uses Rock Hard 4x4 Parts' patented locking collar connections, which are said to be the strongest of its kind. All components of the Ultimate Sports Cage are 100-percent made in the USA at Rock Hard 4x4 Parts' 30,000-squre-foot manufacturing facility in Nebraska.

The Jeep JK Ultimate Sports Cage kit includes everything from the factory B-pillar hoop forward to the dash and it fits hard or soft top-equipped two- and four-door Jeep Wrangler JKs. It even works with the factory Freedom Top panels. All connections to the factory bars are made with 1/2-inch-thick, CNC-machined clamping collars that are secured using six 5/16-by-1-inch Grade 8 socket head cap screws. The tubing is 1 3/4-inch by 0.120-inch-wall. The Ultimate Sports Cage does not affect the factory windshield mounting, sun visors, or top latches, and the windshield can still be folded down.

The Ultimate Sports Cage adds to the factory sport 'cage rather than replacing it so no welding is required for installation, only minor drilling and modifying some plastic trim pieces. As a result, the Rock Hard 4x4 Parts' Ultimate Sports Cage provides a factory finish look.

With parts in hand we traveled to Brothers 4x4 in Montclair, California. The experienced Brothers 4x4 crew made quick work of the installation and had the parts in place in no time. Check out the photos for the details.

With the drivers-side A-pillar bracket bolted in place the dash bar was then installed on that side and sandwiched between the passenger-side A-pillar bracket. The Rock Hard 4x4 Parts Sports ’cage features 1 3/4-inch by 0.120-inch-wall tubes and 1/2-inch-thick, CNC-machined clamping collars that are secured with 5/16- by 1-inch Grade 8 socket head cap screws.
