The RH4x4 Jeep bolt-in Sport Cage is the cornerstone of Rock Hard 4x4™ products. 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.

The Why - Factory Design Complications
The Wrangler JL almost didn't come to market with solid axles. Weight was a major factor in determining if the Wrangler would sacrifice off road capability for fuel mileage standards. In the end, and what we have today, is a Wrangler attempting to both satisfy regulations and maintain its heritage. To save weight, and save solid axles, the JL engineers installed a very light weight, very thin wall (14 gauge), very body-integrated cage system.

The engineers produced an extremely hardened, odd shaped tubular design. In developing our Cage Brace System, we broke virtually every drill bit in our building. The tubing is unlike any material Jeep has ever used, certainly in the occupant safety realm. The shape requires a new way to install a Cage Brace System, and a back to the drawing board approach for us. After a fully year of research and development, we're proud to release our innovative design.

Installation
We promised we'd innovate a no-weld design, and we've done it. Our Cage Brace System strengthens the weak/vulnerable points in the OEM JL cage plus adds functionality. Our System does require some special tools, but does not require welding.

Drilling - The new factory cage material, while only 14 gauge, is hardened. It takes a very slow (300 RPM ideal, 500 RPM max) drill process and a special hardened cobalt drill bit to penetrate. Your big box store drill bits will not work. You aren't required to purchase, but may very well need, an additional Drill Bit Pack.



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.

Is any welding required?
No.

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!

Great Product, Easy Install
This is a great product and makes putting harnesses in your Jeep with your stock cage a breeze. As they mentioned, slow drilling is your friend. I ended up breaking the supplied bit second to least hole. Also like they mention, your average drill bit wont work. However, I went and bought a Milwaukee Cobalt, Heavy Metal bit, and it cut like butter and was under $15 per bit. I was very impressed

Harnessbar for glafiator
Shipping on the harnessbar was very quick. It’s wel made and extremely precise with fitment. There wasn’t a bit included but when I reached out about the missing bit they had it to my door the very next day. So that is exceptionally noteworthy of their customer service and action on fulfillment. Very pleased.
