The RAM 1500 TRX, launched in 2021, was a direct response to the growing demand for high-performance off-road trucks, specifically targeting the Ford Raptor. Built on the DT generation RAM 1500 platform (introduced in 2019), the TRX distinguishes itself with a significantly upgraded suspension, wider track, and, most notably, the 6.2-liter supercharged HEMI V8 engine. This engine, previously found in the Dodge Challenger and Charger Hellcat, delivers a substantial 702 horsepower and 650 lb-ft of torque, making the TRX the most powerful production pickup truck at its launch. The TRX is exclusively offered as a Crew Cab, emphasizing its focus on both performance and passenger comfort.
Powertrain & Engine Architecture
The heart of the TRX is the 6.2-liter HEMI V8 engine, internally designated as the ESD code. This engine utilizes a roots-type supercharger with dual fuel injectors per cylinder – one for low-load efficiency and another for high-performance demands. The engine features forged connecting rods and pistons, strengthened crankshaft, and high-flow cylinder heads. Fuel delivery is managed by a multi-port fuel injection system. The overhead valve (OHV) valvetrain, while traditional, is optimized for durability and performance. The engine’s 9.5:1 compression ratio balances power output with reliability.
The engine is paired with a ZF 8HP75 eight-speed automatic transmission, specifically calibrated for the TRX’s high output and off-road application. This transmission features robust internals and quick, precise shifts. The four-wheel-drive system is a full-time system with an electronic locking rear differential and a selectable transfer case offering various terrain modes, including Rock, Mud/Sand, and Snow.
Driving Characteristics
The TRX delivers exhilarating acceleration, achieving 0-60 mph in approximately 4.5 seconds. The supercharger provides instant torque, making the truck feel responsive even at lower RPMs. The 8-speed automatic transmission is well-tuned, providing smooth shifts and keeping the engine in its optimal power band. However, the sheer weight of the TRX (over 6,300 lbs) is noticeable, particularly during cornering. The upgraded suspension, featuring Bilstein Black Hawk e2 shocks, effectively absorbs bumps and provides excellent control both on and off-road. The wider track and increased ride height contribute to enhanced stability. Compared to the standard 1500 models, the TRX offers a far more aggressive and planted driving experience, sacrificing some on-road refinement for superior off-road capability.
Equipment & Trim Levels
The TRX came standard with a comprehensive list of features, including a 12-inch touchscreen infotainment system with navigation, premium leather upholstery, heated and ventilated front seats, a panoramic sunroof, and a premium sound system. Unique TRX-specific interior trim elements, such as aluminum pedals and carbon fiber accents, further distinguish it from other 1500 models. Optional extras included a head-up display, advanced safety features like adaptive cruise control and lane-keeping assist, and various appearance packages.
Chassis & Braking
The TRX’s chassis is heavily reinforced to handle the increased stress from the powerful engine and off-road use. The front suspension utilizes a double wishbone setup with unique upper and lower control arms, while the rear suspension employs a multi-link spring system with remote reservoir shocks. The brakes consist of ventilated discs at all four corners, with larger rotors and calipers compared to other 1500 trims. The TRX also features an electronic stability control system with off-road calibration.
Market Reception & Comparison
The RAM 1500 TRX was widely praised by automotive critics for its exceptional performance and off-road capability. It was consistently lauded as a worthy competitor to the Ford Raptor, and in some cases, even surpassed it in terms of power and overall driving experience. Fuel economy, however, was a significant drawback, averaging around 12 mpg in combined driving. Compared to other 1500 trims, the TRX commanded a substantial price premium, reflecting its specialized nature and high-performance components. The standard 1500 models with the 5.7L Hemi V8 offered better fuel economy and a lower price point, appealing to buyers prioritizing practicality and value.
Legacy
The RAM 1500 TRX established a new benchmark for performance pickup trucks. Its powerful engine, robust suspension, and aggressive styling have cemented its place as a desirable vehicle in the used car market. While production ended in 2024, the TRX remains a sought-after truck among enthusiasts and those seeking a high-performance off-road machine. The powertrain, while known for its power, requires diligent maintenance, particularly regarding oil changes and supercharger lubrication. Overall, the TRX represents a bold and successful attempt by RAM to create a truly exceptional performance pickup truck.
