$109.95

Rockhard 4x4

Model #RH-9054


Shopper Award

Not compatible with JL and JT housings as they are not traditional Dana 30 and Dana 44 center sections like we know them. We hope to have our HardHats for the JL and JT finalized soon.

Rock Hard 4x4 is very proud to offer the Heaviest Duty 1/4" Thick Steel Differential Cover for the Dana 30 Housing.

Our Differential HardHat's are designed to offer maximum protection where your rig needs it most. The factory differential cover offers minimal protection and provides zero deflection. In minutes, you can install a 1/4" thick plate steel cover with built-in impact deflecting angles. We've laser cut-out an oil change cutout to make servicing a breeze.

Million Dollar Question:
Why not a full differential cover replacement? Same reason we do not attach our best-selling JK Oil Pan Skid Plate directly to the oil pan. We are moving hard impacts away from your internals as far as we can, while maintaining clearance for your suspension/track bars. This gives you the best of both worlds: Ultimate 1/4" thick steel drive train protection with maximum off road clearance.

What comes in every kit:

  • Differential Cover HardHat
  • Zinc-coated Hardware
  • Installation Instructions
  • Included/Not Installed Stainless Steel Backing Plate
Three Reasons Why:
  • Protects critical drivetrain components
  • 1/4" thick plate steel

FAQ:

What track bars and/or tie-rods are compatible?

What is Rockhard 4x4?

The concept for Nebraska-based Rockhard 4x4 was started in the 1980s by Lewish Barth and his son, James. The two of them had been building off-road cages and bumpers for more than 20 years. By the 1990s, the duo was building so many cages for friends that transporting them became quite difficult. Welding the cage in was not something that everyone could do, and that’s when the bolt-in design was born. It was at that time that Rockhard 4x4 became home of the “do it yourself” cage installation. The brand has since evolved from DIY cage installation to a full-service manufacturing plant.

Why Choose Rockhard 4x4?

Rockhard 4x4 employs state-of-the-art CNC machining centers and combines that with laser cut precision and extraordinary craftsmanship. With this approach, Rockhard is able to take the bolt-in design of bumpers, cages, sliders, and skid plates to the next level. The company’s patented locking collar design sets itself apart in the aftermarket industry with its superior quality and proven strength. The locking collar connection is irrefutably strong and arguably stronger than other weld-in cages. While many competitors have tried to duplicate its design, none have come even close to the quality and workmanship offered by Rockhard 4x4. 

Rockhard 4x4 is known for producing exterior products that make off-roading in Jeeps a lot safer, smoother, and more comfortable. Its products are easy to install, provide paramount protection, exude aggressive styling, and won’t break the bank.

Quality Made in the USA

Rockhard 4x4 proudly manufactures all of its parts and systems in its 30,000 square-foot production facility in Nebraska. There is a certain level of quality and control you can only maintain when building products in the U.S. with a family running the show, and Rockhard proves just that. The experts at Rockhard 4x4 are off-road enthusiasts and wheelers themselves, so they know just how to manufacture armor that will instill confidence in the customer and provide strength-proven protection on America’s most demanding trails.
