Rock Hard 4x4 is very proud to offer the Heaviest Duty Transmission Crossmember for the Jeep Wrangler JK 2/4DR 2007 - 2011 3.8L.

Upgrade your factory 14-gauge stamped steel transmission crossmember to our 3/16" + 3/16" MASSIVE 3/8" DoubleWall Crossmember!

Total Weight: 27 lbs.

Our top and bottom plate 3/16" thick design gives you a total of 3/8" plate steel strength! Designed to fit 2007-2011 3.8L engines.

Ease of Install
In under 1 hour - including removal of your factory crossmember - you can complete this critical upgrade. We designed this crossmember to be a drop in replacement for your factory transmission crossmember. Simple hand tools required - no drill cutting or welding!

Precision Made Strength
Each crossmember is laser cut from 3/16" thick steel and coated in our weather and debris resistant powder coat finish. Strength is proven on virtually all Jeep enthusiast forums with glowing reviews. Since 2007 our skid plate system has been the undisputed leader in undercarriage protection.

RH4x4 crossmembers are very recognizable for two major reasons: beefy unmatched strength and laser precision fitment. What makes up a RH4x4 crossmember is what makes it so strong.

Powder Coated Finish
Other crossmembers on the market come bare steel adding an unexpected and unfortunate setback. Ours comes ready to install right out of the box.

Wire Harness Retention
Other crossmembers on the market leave no provision for the factory wiring harness that you must somehow zip tie or tuck out of the way. Our crossmember includes pre-cut holes for the wire harness loom plugs.

What comes in every kit:
  • Crossmember
  • Installation Instructions

Three Reasons Why:
  • Installs in Minutes
  • 3/8" Thick Plate Steel Side Protection
  • Powdercoated

Is any welding required?
No. Our mounting method allows for a DIY no-weld, truly bolt-in install.

What finish is available?
Rock Hard 4x4 skid plates ship powder coated black with a semi-smooth, semi-gloss finish.

Where is this crossmember made?
This product, like all RH4x4 parts, was designed, developed, tested, manufactured, and if applicable, powder coated, and shipped in the USA. And we don't mean the 75% legal standard to be able to say Made in USA. We are 100% Made in the United States of America!
