Ram Rebel TRX Engine

Engine Features

The engine of the 2021 Ram 1500 TRX boasts best-in-class horsepower, and torque so, you don’t need any additional noise enhancements to produce an authentic sound. Some key features of the supercharged V8 engine are:

Powerful Supercharger

The twin-screw supercharger with a maximum speed of 14,600 rpm offers instantaneous torque and can regulate boost pressure up to an astounding 11 psi.

Massive Airbox

The 2021 Ram Rebel TRX is equipped with a high-performance air induction system. This system filters four times as much dirt, and debris as compared to its competitor Ford Raptor. In addition, it consumes up to 32.9 liters of air per minute.

Legendary Engine Block

The engine block of the truck is engineered to withstand firing pressure of 1595 psi which is equivalent to 20,000 pounds of force. The block is built with a robust cast-iron block that restrains a forged-steel crankshaft with induction-hardened bearings.

Drive Modes

The 2021 Ram Rebel TRX is featured with performance-tuned drive modes that work as per your command and requirements. The drive modes are applicable for on and off-road excursions.

Sport Mode

The sport mode allows quicker shift times and comes with a tightened suspension setup. The TRX offers optimal performance on paved surfaces with the sport mode powered with a 30/70 torque split and sport-tuned stability control system.

Snow Mode

As the name suggests, the TRX offers optimal performance on snow and icing conditions with the snow mode. The Snow Mode employs a 45/55 torque split and manages engine horsepower for optimum performance.

Sand/Mud Mode

The 2021 Ram Rebel TRX with Sand/Mud mode utilizes a 45/55 initial torque split, and calibrates throttle management, and torque distribution to prevent wheel slip, and enhance traction in deep sand, and mud conditions.

Rock Mode

The TRX on the Rock Mode shifts to an extra-low gear ratio and utilizes a 50/50 torque split to offer excellent performance in rocky driving conditions. In addition, the available Selec-Speed Control system assists in holding a set velocity for a controlled descent in steep rock conditions.

Baja Mode

The Ram 1500 TRX reduces shift times by 68 percent, sets its suspension on full damping, and allows for moderate oversteer to impart maximum fun. This mode is suitable when taking on dunes.

Custom Mode

Owners of the 2021 Ram Rebel TRX can create a custom-tailored driving experience by setting their preferred steering feel, torque split, suspension firmness, and other features.

Performance Features

The TRX off-road truck is featured with a digital instrument cluster and 12-inch touchscreen. The Launch Control, Dashboard, Dyno/Engine, and Vehicle Dynamics describe the performance of the truck.

Launch Control

The 2021 Ram Rebel TRX is the first Ram truck to be featured with Launch Control System that contains the Launch Assist. This system regulates engine RPM and monitors wheel slip feedback in order to always achieve the fastest possible acceleration rate.


The integrated dynamometer allows you to measure your peak horsepower, torque, and enhance pressure in any conditions. With the measured data, you can compare it to previous records.

Vehicle Dynamics

You can use the Vehicle Dynamics page to dial in the maximum steering angle, lock your axles, and modulate your transfer case gearing when in off-road driving conditions.

Ram Active Terrain Dynamics

The Ram 1500 TRX is equipped with Bilstein Black Hawk e shocks that continuously adapt to varied terrain conditions. The Bilstein Shock comes with features including the Bilstein Algorithm, Dual-Valve Technology, High-Pressure Stainless Steel Braided Hoses, Remote Reservoirs, and ZoneControl Jounce Cut Off.

Bilstein Algorithm

The Bilstein Algorithm is introduced to offer extreme performance capabilities of the TRX. The proprietary control algorithm monitors vehicle sensors and continuously adapts to speed, throttle position, braking torque, steering angle, and much more. The truck offers enhanced body control in both on-road, and off-road conditions.

Bilstein Technology

The Bilstein e shock comes with dual-valve technology that allows the system to infinitely adjust compression, and rebound forces at each shock absorber. The system will react, and tailor the signal being dispatched to each of the eight valves on TRX with enhanced precision. The technology works in accordance with the terrain, and driver input.

Each hose of the Bilstein e shock is protected by a braided stainless steel outer layer and sealed using a metal-to-metal process which is common to aerospace, and motorsports applications. It allows the hose to withstand temperatures of up to 275-degree Fahrenheit, accommodate pressures over 5800 psi, and prevent abrasion, and corrosion.

In addition, each shock is powered by a pressurized nitrogen gas charge in an independent remote reservoir. This allows extreme suspension articulation after freeing up room in the shock absorber for piston rod travel.

Besides, a secondary piston activates to prevent bottoming out as the shock absorbers approach full compression after a hard landing.

Exterior Features

Air Intake Scoop

A menacing grille, functional air intake scoop, and flow-through R-A-M badge ensure unobstructed airflow to the engine. Moreover, integrated amber identification lamps create a signature look.

Wide Fenders

The premium LED Smartbeam intelligent headlamps are integrated into widened fenders. These wide fenders are flared eight inches to accommodate seven strategically placed air flow features.

Available Accessories

The 2021 Ram Rebel TRX offers available Mopar accessories that include a bed-mounted spare tire carrier, and RamBar.

High-Performance Exhaust

The TRX comes with a dual exhaust system with high-performance capability. The system utilizes two resonance-free pipes to produce an enthralling growl from the massive 5-inch matte-black exhaust tips.

Interior Features

Flat-Bottom Steering Wheel

The 2021 Ram Rebel TRX is equipped with the first performance-focused steering wheel integrated with aluminum shift paddles, a flat-bottom shape, available carbon fiber, and Alcantara suede accents.


The Ram 1500 TRX is featured with a Head-Up Display (HUD), and 19-speaker Harman Kardon Premium Audio System. The all-new available HUD feature offers you a virtual cockpit that projects an array of customizable information on the windshield.

The TRX is also equipped with an available 900-watt Harman Kardon Premium Audio System that includes 19 speakers and features exclusive materials.

The innovative dashboard of the truck offers information related to the monitor instantaneous horsepower readings, personal records, steering angle measurements, and much more.

The integrated switch bank of the truck features up to 6 auxiliary buttons, and an available Trailer Reverse Steering Control System. The gear shifter is placed at the center with a manual shifting mode.

The interior also features TRX-exclusive badges on the center console cover and glove box. In addition, the aluminum shift paddles are integrated within the flat-bottom steering wheel for the first time ever on a Ram truck.
