The résumé of this world-famous engine includes propelling WWII Thunderbolt
airplanes, helping define the distinctive Muscle Car Era, and vaulting new 2013 Ram
Heavy Duty pickups to first-place consideration for the toughest jobs you face —
whether hauling iron from the factory, or climbing that mountain with your camper.
The manifold advantages of the unstoppable hemispherical design of the 5.7-liter
HEMI V8, along with VVT, are detailed at left. Now add robust transmissions and
transfer cases to expand capability; all components utilize technologies and
engineering protocols created specifically for heavy-duty use and long-term
durability. And in this economy, improving performance and increasing fuel
efficiency are bottom-line specific, for today, it’s all about doing business better —
and that includes HEMI V8 performance. With its hemispherical heads and VVT-
engineering that improves engine breathing for increased response and torque —
HEMI V8 performance makes it the natural standard powerplant for Ram 2500 and
3500 SRW models.
Powertrain partners to the HEMI V8 add strength. Mated to the Ram Heavy Duty
5.7-liter HEMI V8 is the sophisticated 66RFE six-speed automatic transmission, a
component that exceeds typical demands for anticipated towing and hauling. The
transmission offers driver-adaptive shifting, with three multiple clutch packs and a
dual-stage hydraulic pump, all contributing to superb road manners and impressive
hauling dynamics. The addition of dual filters on the dual-stage pump helps protect
the pump and other components, with an independent lubrication cooler ensuring
ample pressure under all conditions.
The transfer cases mated to the 5.7-liter HEMI V8 are the same as those utilized
by the Cummins
®
Turbo Diesel — applications that prove unquestionable strength.
The BorgWarner BW 44-46 transfer case features responsive electronic shift-on-the-
fly engineering, with three operating ranges, plus Neutral. The manually actuated
BW 44-47 case features three operating ranges, plus Neutral. Both units offer a
low range reduction ratio of 2.64:1 — ideal for slow rock crawling or steep grades.
When it comes to off-road capability or on-the-job performance, Ram Heavy Duty is
designed to excel.
