If the Power Wagon is on your radar, it’s likely that its hard-core hardware put it there. For 2017, the Power Wagon’s rear axle gets upgraded to an 11.5-inch (ring gear) unit from the previous version’s 10.5 axle, while a 9.3-inch unit resides in front. Both feature 4.10:1 ratios. The rear axle shafts are enlarged, and electronic locking differentials are fitted front and rear. Like all Ram Heavy Duty trucks, the front axle uses a disconnect system when not in four-wheel drive to reduce parasitic loss, wear, and fuel consumption. Ram claims the system provides a gain of up to 1 mpg.
As before, power comes from the corporate 6.4-liter Hemi V-8, rated at 410 horsepower and 429 lb-ft of torque. Engine output is funneled through a six-speed automatic transmission to a part-time BorgWarner 44-47 manually shifted transfer case. When driving in 4WD Low, the throttle response is softened, and the engine's idle speed increases from 650 to 750 rpm for crawling. Hill-descent control allows drivers to govern the Power Wagon’s speed down steep grades via buttons on the column shifter. Skid plates for the fuel tank and transfer case help protect those vital components.
The front suspension features Bilstein monotube dampers and an anti-roll bar that can be disconnected to allow greater axle articulation. Disengagement is possible at speeds below 18 mph when in four-wheel drive; it automatically reconnects at speeds above 18 mph. The coil-spring live axle in the rear also gets Bilstein shocks, as well as a third Bilstein damper that connects the top of the axle to the truck’s frame.
Sporting 14.3 inches of ground clearance, the Power Wagon betters the standard 2500 HD 4x4 in that area by more than two inches. The Power Wagon has an approach angle of 34 degrees, a departure angle of 26 degrees, and a breakover angle of 24 degrees. Water-fording capability is claimed to be 30 inches.
As you would expect, many of the most popular options available on non–Power Wagon Rams can be specified: a spray-in bedliner, LED bed lighting, rearview and bed-view cameras, front and rear park assist, power-adjustable pedals, and remote start all can be ordered. Another cool Power Wagon feature is the optional dual-alternator system, which combines separate 220- and 160-amp alternators for a hefty 380 amps of total output. Dual alternators are particularly handy if you plan to load up on high-draw aftermarket electronics, like off-road lights or a snowplow.
Overall, the 2017 Power Wagon deviates very little from the path it’s been on since the original military-bred version first hit the dirt in 1945, and that’s a good thing.
