3D Offroad is Colorado’s only America’s Most Wanted 4x4 dealer. We have been a dealer since 2022 and proud to offer high quality engine swaps to our customers.

A few things we love about the Hemi swap:

  • Factory Look - each swap looks like a factory installation with genuine MOPAR parts.

  • Seamless Integration - with the engineering from AMW 4x4, these conversions include everything needed to make the kit work flawlessly.

  • Warranty - all conversions include a 2-year/24,000 on engine-conversion parts and 1 yr warranty on labor by approved licensed repair service centers when AMW4x4 installs the HEMI® Conversion Package.

  • More Power - adding a V8 to your Wrangler or Gladiator is always a good option!

  • It truly depends on your lifestyle and vision for your build! The AMW 505 is our most popular option but we can install any kit (except the AMW 1000) from AMW 4×4. Our team is great at giving you recommendations based on your vision and goals.

  • All vehicles must have a 2” lift to accommodate the conversion. If your Jeep is stock, expect to add more upgrades with your conversion. Common upgrades to accommodate more power are axles, gears, tires and lift kits.
