Gecko Green HELLEPHANT-Powered Gladiator Took $242,000 At Barrett-Jackson!

AMW4x4's Awesome 8-Lug 1,000 Horsepower Gladiator...

A couple of weeks ago, we highlighted a special build that the team at America’s Most Wanted 4×4 (AMW4x4) had built for the Barrett-Jackson Scottsdale event late last month. The AMW4x4 team is known for their outrageous but refined HEMI-powered Jeep® Wrangler and Gladiator builds, some of which we have featured on MoparInsiders.com. Their most recent build involved a 2021 Jeep Gladiator Rubicon in the popular Gecko Green exterior color.

Starting with a 2021 Jeep Gladiator Rubicon as the base, the AMW4x4 team added its “AMW 1000” package to the Gecko Green pickup. The AMW 1000 Package adds the outlandish 7.0-liter (426 cubic-inch) HELLEPHANT HEMI V8 with a 3.0-liter IHI supercharger on top from the Mopar crate engine program. The motor was only produced for a limited run before the pandemic (although, it will return later this year) and puts out a whopping 1,000 horsepower and 950 lb.-ft. of torque at the crank without any modification.

But the AMW 1000 Package is no simple HEMI engine swap. Instead, AMW4x4 fitted the Gladiator with a proven and tough 8-speed TorqueFlite 8HP95 automatic transmission from the high-performance Grand Cherokee Trackhawk. The AMW 1000 Package doesn’t stop there, the package includes numerous performance upgrades to ensure that their Gladiator’s are not only fast but bulletproof as well. Those upgrades included in the AMW 1000 Package include…

When all was said and done, the Gecko Green-colored Gladiator AMW 1000 achieved a sale price of $242,000. That seems like a steal for such a custom pickup, considering some of the cars we have been seeing for sale recently.

If a HELLEPHANT-powered Gladiator is out of your reach, the AMW4x4 continues to offer a number of HEMI performance upgrades for the Gladiator and Wrangler ranging from…

  • 6.4-liter (392 cubic-inch) HEMI “Apache” V8 with the AMW 505 Package
