Inside And Out
As we detailed in our deep dive, there’s a lot more going on here than just a standard Ram 1500 with a Hellcat engine. Sure, there is a supercharged 6.2-liter Hemi V8 under the hood making 702 horsepower and 650 pound-feet of torque, but it’s almost a side note amongst the arsenal of weapons-grade hardware that this truck is outfitted with.
It all starts with the frame, which Ram says is 74% unique versus a standard 1500. Along with its fully boxed side rails, sections of the TRX frame have been hydroformed to reduce weld points, and high strength steel replaces the standard material in areas that will see the most abuse.
The TRX features a high-strength steel frame with independent suspension in the front and a live axle in the rear.
The front shock towers are particularly noteworthy, as TRX chief engineer Jeff Roselli pointed out during the technical presentation, because they’re made from the thickest steel that Ram could possibly stamp. “We designed this truck to outrun and outlast the competition,” he explained. “And that starts with a strong foundation.”
Bolted to that foundation is a significantly upgraded suspension system that consists of a five-link with a Dana 60 solid axle in the rear and an independent setup up front with unique, forged aluminum control arms that are designed to accommodate more wheel travel and axle track width. The dampers are the real party piece here, though: Developed exclusively for the TRX by Bilstein, these 2.5-inch adaptive shocks are equipped with dual electronic proportional valves that continuously adjust damping force as well as nitrogen-charged remote reservoirs that keep fluid temperatures down and extend the life of the shock.
To address not only with the TRX’s requirements for mud, sand, snow, and rock crawling capability, but also its 118 mph top speed, Ram turned to Goodyear for a specially developed all-terrain tire as well. The 35-inch rubber is wrapped around an 18-inch aluminum wheel as standard, while an 18-inch, beadlock-ready wheel is optional.
As with the Jeep Grand Cherokee Trackhawk, the Ram 1500 TRX sends the blown Hemi’s grunt to all four corners through a ZF-sourced eight-automatic transmission. Unlike standard Ram 1500 models, the TRX has a traditional console-mounted shifter that allows for manual control over the gear changes, either by bumping the handle over to the left while in gear or by grabbing the steering wheel-mounted shift paddles.
The interior differentiates itself from garden-variety 1500s in other ways, too. A unique flat-bottomed steering wheel gives the cabin a racier look and feel, while the a “TRX” button on the dash loads up a unique version of Performance Pages that combines go-fast telemetry data from the SRT side of things with the Ram Rebel’s off-road information. Below that button is a toggle for the truck’s various drive modes. There’s seven in total, ranging all the way from the street-oriented Auto and Sport modes (the truck reverts back to the former each time the engine is started) to Rock and Baja modes. The latter adopts a more aggressive transmission schedule and reduces shifts times to keep the engine on boil, puts the dampers on high alert, and relaxes the traction and stability control software to allow for more oversteer before the systems intervene.
The TRX also visually stands out from other 1500s not only due to its unique aluminum hood and taller stance, but also because of its eight-inch increase in overall width, which comes as a result of the composite fender flares up front and new steel outer box stampings in the rear.
Judging by the laundry list of upgrades here, it’s clear that Ram has sweated the details from top to bottom with the TRX. But is it actually any good to drive out in the real world? Earlier in the day, I decided to take the long way from the hotel in Lake Tahoe to the track in order to find out.
