[5] The non-production modifications of the concept prototype include 37-inch tires mounted on Mopar 18-inch bead-lock wheels featuring body color matched rings, two full size spare wheels and tires in a bed mount configuration also featuring a lockable unit housing a jack, tow strap, and room for more tools.

Other production departures include a six inch wider track with extended fenders to cover the wider wheel base, giving the truck an hourglass look when viewed from above, LED clearance lights, a tire rack mounted LED light bar, five inch side exhaust integrated into protective rock rails, skid plates, a 6.2-liter supercharged HEMI V8 engine based on the popular Hellcat featured in Dodge Chargers, Challengers, and the Jeep Grand Cherokee Trackhawk, but detuned for the truck application to 575 horsepower mated to a TorqueFlite 8HP70 transmission and a BorgWarner 44-45 transfer case.

The link coil based suspension is upgraded with performance springs, 2.5-inch King Racing Shocks and feature a 40% increase in travel to 13" front and rear from the standard 9".

The interior also features multiple deviations from the stock Ram Rebel 1500 including suede inserts in the seats, "sport-sanctioned lateral support upper bolsters with embroidered logos", six point harnesses, cloth door pulls, a console shifter, a rotary selector for the various drive modes, an anodized steering wheel with accent stitching, paddle shifters, a tool bag featuring TRX labeling, carbon fiber and red metal inlays, a camera mount near the rearview mirror, and a sport bar to which the six point harnesses mount.

[12] However, the 2019 Dodge Challenger SRT Hellcat Redeye was announced in August that same year which featured essentially the same engine from the Dodge Challenger SRT Demon with variations on the air intake dropping the Redeye's horsepower rating to 797 from the Demon's 808 (also, the 2019 non-Redeye Dodge Challenger SRT Hellcat features airflow improvements raising its horsepower rating to 717 over the prior year's 707).

[14] exceeds the characteristics of the Redeye engine, but is also not expected to be part of the production Ram Rebel TRX configuration (when asked, "members of the Mopar team" responded "absolutely not" regarding whether or not the Hellephant engine was being considered for any street applications, which would necessarily rule out inclusion of the production Ram rebel TRX).

All Ram 1500 TRX models were all equipped with a supercharged 6.2-liter (380 cu in) Chrysler Hellcat Hemi, which produces 702 horsepower (523 kW) and 650 pound force-feet (881 N⋅m) of torque.
