2021 RAM 1500 TRX 4×4 – Bottom Line Review

2021 RAM 1500 TRX Crew Cab 4x4: Five mandatory NHTSA amber front ID Lamps embedded in the hood betray the girth of this Cretaceous mechanical monster. Starting at $72k, as tested at $91k.

PRE-HISTORY VS. HOLLYWOOD: Michael Crichton’s epic 1991 novel “Jurassic Park”, followed by Steven Spielberg’s 1993 screen adaptation, tells a suspenseful tale of extinct pre-historic Sauroids revived for a 20th century island amusement park. The forewarning, often echoed in these times, expounds upon the dire consequences of humans exploiting nature.  

APEX DINER: Entertainment value dictated that the author and director would take liberties with paleontological information. However, both Crichton and Spielberg, got at least one dramatization right. Fossil finds demonstrate T[yrannosaurus]-Rex devours [Veloci-] Raptor. Should any doubt remain about who eats who one look under the engine air cleaner cover of Stellantis latest to pick-up truck, the 2021 RAM 1500 TRX 4×4 will “clear” that up.

WHAT: 2021 RAM 1500 TRX Crew Cab 4×4 pickup truck. A mutation of the 5th generation DT series half ton packed with Hellcat power. Bred with serious desert dune racing capability it’s RAM’s ferocious response to the Ford F-150 Raptor 4×4.

Standard Powertrain: 6.2 liter “Hellcat” intercooled supercharged gasoline overhead valvetrain V-8 engine, 702 horsepower; 650 pound-feet at 4800 r.p.m., same as found in any Dodge Charger Hellcat.

By Comparison: to Ford F-150 Raptor

    • 702 horsepower vs. 450 hp = +56%
    • 650 pound-feet vs. 510 lb-ft torque = +27%
    • 113 horsepower / Liter displacement  vs. 128 hp/L = -12%
    • 6359 pounds vs. 5525 pounds = +15%
    • 11.8 inches vs. 11.3″ ground clearance
    • 0-60 mph: 4.7 seconds vs. 5.2 sec.

WHAT (A) STYLING DIFFERENCE: The “Big Rig” engine forward, low slung fenders with low mount headlatmps and tall cross haired grille began with a 3rd generation Dodge Ram DR series, muscularized for the 4th generation DS series Ram. Based on the 5th generation RAM 1500 pickup, the RAM 1500 TRX follows the same  “aero” approach more to with taller fenders and headlights positioned on the flanks of a no longer crosshaired multi horizonatal slat upper grille.

“RAM TRX” theme = similar to RAM Rebel 1500 = darkened grille w/ dark lattice inserts; Straked hood dual intake NACA intake ducts; Darkened bumper covers & lower fascia; Exposed darkened front lower skid plate; Darkened window frames & mirror caps; Two-toned darkened lower body; Larger dark wheel arch cladding; Two-tone beadlock tire capable alloy wheels; Rear quarter panel “TRX” appliques.

    • 6.0″ inch combined added fender width vs. Ram Rebel 1500 earn DOT illuminated side markers
    • 8.0″ width vs. NHTSA wide vehicle standard earns 3 amber lamps embedded in hood center snorkel

WHY: As per cinematic paleontology, new reigning terror of Cretaceous apex predator pickup trucks is able to devour current Veloci “Raptor” AND it’s lunch. 

WHEN: On-Sale (in the U.S.) since Spring 2020

WHERE: RAM new truck dealers

WHERE MADE: Sterling Heights, Michigan, U.S.A.

WHERE TO: High four-wheel drive on the fly is but a twist of the electronic two-speed helical gear transfer case selector knob. Where improved roadway ends, the air-suspension provides about an inch greater wheel articulation while light truck knobby Goodyears grab the dirt. Skid plates protect engine, transmission, transfer case & fuel tank in the event of rock climbs. During daring dune jumps RAM TRX’s 198.4 cubic inch surface air cleaner element filters 4 times the sand and dust of the competitiion. TRX Off-Road mode data can be displayed in the gauge cluster 7.0″ TFT multi-function display while custom settings happen via the 12.0″ LCD portrait infotainment screen TRX Performance Pages.

  • Terrain Management modes torque split: 40/60% Auto, 45/55% Snow, Tow, Mud & Sand, 30/70% Sport, 25/75% Baja, 50/50% 4-Low Rock Crawl
  • Jump Detection: accelerometer detected airborne status of TRX and prepares driveline and suspension for landing

HOW STRONG: Like a bull that hasn’t been broken of all its independence the RAM TRX lets the community know who is the boss. Make that the entire county. The tall climb into the cab is a deterrent to those of poor balance. A red dash-mount ignition button ought to glow to warn of potential risk ahead. The push-rod small block V-8 comes breathes life with an unstressed thrum, thrum, thrum, thrum resonance from the dual exhaust with crossover pipe. Tooling in town TRX lumbers, snorting a bit, the supercharger making a background hissing, absolutely under-utilized.

Push those heavy Red Wings into the accelerator after some lengthy tip-in, the beefed up German built 8-speed ZF kicks down firmly. Vacuum cleaner whirring emanates from the twin screw blower voraciously gulping air. The 3.0″ dual catback exhaust issues an exorcized demon’s wails. More than three tons of mobile brick signals “Get out of the way” to all else on the road. The only adversary at high speed clips is a bit of an aerodynamic wall. RAM estimates that with the right rubber 150 miles per hour would be within the RAM TRX’s reach. All-wheel drive high defeats the rear drive Hellcat Charger’s all hell break’s lose launch antics, allowing but a whiff of tire chirp. A beefier drive-line is less susceptible to abrupt power judder, and the cabin is nearly too insulated rendering the symphonic experience to Strauss’ “Also Sprach Zarathrustra.”

    • Performance Pages, accessible via dashboard driver’s knee side TRX Mode switch, dispatches driver selected five drive modes and as brutal a brake torque Launch Control imaginable via the 12.0″ Uconnect infotainment screen.

HOW LIMBER: Tipping it’s suspension hat to the challenge of daunting off-road terrain, the RAM TRX suspension control arms, links and bushings are substantially strengthened from your ordinary RAM 1500. The very Bilstein e2 Blackhawk remote reservoir variable dampers which must independently respond to as much as 14″ inch wheel articulation yield a relatively jounce free and at times supple ride compromise. Progressive rate coil springs, measuring more than 2 feet when uncompressed, help maintain body composure in turns. Wide all-terrain rubber preclude razor sharp turn in and road feel is repressed but the steering effort varies with deft acuity. Hard braking serves up a good amount of nose dive. Lacking the fixed multi-piston calipers of Hellcat cars, firmer pedal application is demanded in the RAM TRX to slow considerably.

Suspension Special Bits:

2021 RAM 1500 TRX Crew Cab 4×4: double wishbone front suspension with Bilstein e2 Blackhawk bypass dampers = 13″ wheel travel
  • 11.8″ inches ground clearance; 13.0″ inches, 13.9″ inches F:R wheel travel
  • 2.5″ inch diameter Bilstein e2 Blackhawk variable bypass pressurized dampers, remote rear reservoirs
  • Front 2-piston front floating caliper + 15.0 vented rotor F+R brakes
  • 325-65/ 17  Goodyear Wrangler Territory All-Terrain tires = 33.4″ inch diameter
  • Available MOPAR forged bead-lock rims for reduced off-road tire inflation
