This might be my favorite one you've shared thus far. Any more information on the build or any idea where I can find the build info? After some searching I found a Q&A on another Jeep forum but this is all that was said...
"Can you provide details on the build? Suspension, tires? Axle reinforcements?"
"Axels and housing were not reinforced for filming of JOYRIDE Baja. The Jeep’s tires were upgraded to 37” and gear ratios were modified to match the tire diameter. The front and rear suspensions were upgraded to coil over shocks to remote nitrogen canisters."
