Computer Aided Design
Thumper Fab has spent countless hours and multiple prototype revisions to make sure they have developed a kit that will greatly increase strength for your control arm mounts and chassis subframe. They designed the frame stiffener / gusset kit to reinforce weak links and to work with your OEM or Aftermarket Control Arms and Lift Kits with same model year fitment. Using the latest technology in 3D scanning and computer modeling software, all aspects of the suspension and chassis geometry have been verified for precision fitment.

Standard Benefits:

  • Excellent for BIG lifted Defenders with oversized tires for control arm tab mount strength
  • Braces the weakest points on the rear chassis
  • HD powder coated for long lasting protection and to prevent corrosion
  • Made in the USA from premium steel

      High quality, reliable
      Model: Pop up outlet-black
      The units looked really cool and were of excellent quality. They popped up reliably albeit slowly which was fine with me. I was really looking forward to using these in a built in cabinet we're making but they did not fit where I wanted them so I had to send them back. I would buy these again if I ever had a project that needed them.

      Good buy and very useful accessory as a cut in on a table.
      Model: Pop up outlet-black
      Bought these for a new built in enclosed patio buffet table. Everyone always needs plugs for phones, computers, iPads, etc. This is perfect and cover recesses to minimize exposure although mine is not exposed to outside weather.
