The Ram 1500 TRX redefined the high-performance pickup segment by combining desert-running capability with the brute force of a supercharged HEMI V8. This 2023 Ram 1500 TRX Crew Cab 4x4 is finished in Diamond Black Crystal Pearl-Coat over a black leather interior and shows just 19,218 miles. Equipped with the highly desirable TRX Level 2 Equipment Group, TRX Carbon-Fiber Package, Advanced Safety Group, and Trailer-Tow Group, this example is loaded with factory options that enhance both luxury and capability.

If the factory RAM 1500 TRX wasn’t outrageous enough, this 2022 RAM 1500 TRX Ignition Edition takes things to another level entirely. Showing approximately 25,503 miles, this heavily modified supertruck started life as one of the most exclusive TRX variants ever produced, as the Ignition Edition was limited to just 875 units for the 2022 model year. Finished in unmistakable Ignition Orange and equipped with the desirable Level 2 Equipment Group, this example has since undergone an extensive performance transformation. With major supercharger work, fuel system upgrades, camshaft modifications, E85 tuning, and supporting hardware throughout, the current owner reports an astonishing 1,100 horsepower at the crank. Add in the carbon fiber hood, custom vertical doors, and aggressive wheel-and-tire package, and this becomes far more than just a fast pickup—it’s a highly exclusive factory special edition turned full-blown street weapon.
The 2022 RAM 1500 TRX Crew Cab 4x4 is the definition of a modern supertruck, combining extreme power with cutting-edge off-road engineering. Showing just 50 miles, this example is essentially brand new and presents a rare opportunity to own one of the most capable and aggressive trucks ever produced. Built to dominate both pavement and desert terrain, the TRX redefined what a factory pickup could do by pairing supercar-level performance with rugged durability. Finished in Bright White over a bold Black and TRX Red interior, this truck delivers presence, capability, and exclusivity in one package.
