DODGE RAM 2500/3500 HEAVY DUTY
09

WHEN IT COMES TO HEAVY-DUTY WORK TRUCKS KNOWN FOR
LEGENDARY DURABILITY AND UNCOMPROMISING RELIABILITY, ONLY THE
RAM 2500/3500 HEAVY DUTY MODELS ARE BUILT TO CARRY IT ALL:
TOOLS, CARGO, UPFITS, AND PEOPLE. ABOVE ALL, THEY CARRY THAT
REPUTATION FOR QUALITY FEW CAN MATCH. DODGE RAM 2500/3500
HEAVY DUTY. THIS IS HOW THE JOB GETS DONE.

1) Ram 2500 Regular Cab SLT in Bright Silver Metallic 2) 3500 Chassis Cab SLT Dually in Flame Red with Dump Body Upfit 3) Ram 2500 Quad Cab®Big Horn in Brilliant Black Crystal Pearl
4) 3500 Quad Cab Laramie Dually with the 6.7-liter Cummins®Turbo Diesel in Bright Silver Metallic suited up with Diamond Plate Toolbox and Premium Side Steps — Authentic Dodge
Accessories by Mopar 5) 2500 Mega Cab®Laramie with the available 6.7-liter Cummins®Turbo Diesel in Inferno Red Crystal Pearl 6) Power Wagon®in Flame Red.
One of the toughest tasks in the world would be to find a family of
heavy-duty workers to rival the range offered by Ram Heavy Duty.

MEET THE POWERTRAINS THAT POWER THE INDUSTRY. START WITH THE LEGENDARY 5.7-LITER HEMI®
V8, WHERE ONGOING IMPROVEMENTS JUST KEEP COMING. BULLETPROOF TRANSMISSIONS
COMPLETE THE PICTURE.
HISTORY AND LEGEND TEAM UP FOR TOMORROW’S
ENGINEERING. The most recent iteration of the legendary
5.7-liter HEMI®V8 for Ram Heavy Duty pickups now
features Variable Valve Timing (VVT), for outstanding fuel
management and performance across the board.
Additional features that make the HEMI V8 the ideal
choice when only a gas engine will do the job:
MORE POWER. New cylinder heads on the redesigned
HEMI V8 now feature high-flow ports, larger valves and
increased compression ratio; results are measured
directly in performance — with no compromise in fuel
use. It’s all about the engineering: The characteristic
hemispherical cylinder headsare what give the legendary
5.7-liter HEMI V8 such clout in the world of trucks — and
now this world-famous engine is better than ever.
MORE TORQUE. New for the 5.7-liter HEMI V8 is Variable
Valve Timing (VVT), a technology so sophisticated in the
field, it’s utilized on Formula One race cars. VVT offers
increased engine breathing throughout the rpm range by
varying the degree that valves open and close in
conjunction with piston position. The advantages are
seen acrossthe board: better performance, more efficient
operation, and measurable increased torque for towing
and hauling demands.
MORE EFFICIENCY. The new short runner valve (SRV) active
intake manifold: Here, air intake flow is more efficiently
controlled by changing port length based on engine rpm.
At low speeds, the manifold uses a longer port path for
abundant low-end torque; at higher speeds, the manifold
uses a short port; air moves faster to the combustion
chamber. The SRV manifold contributes to more power and
torque — again, without sacrificing fuel economy.
DRIVING THE OTHER HALF OF THE DRIVETRAIN:
THE RAM TRANSMISSIONS.
1 6-SPEED AUTOMATIC. For Ram 2500 and 3500 Heavy
Duty pickups with available Cummins®6.7-liter Turbo Diesel.
Here’s quality measured in durability. The 6-speed with
Electronic Range Select works in concert with the factory-
installed engine exhaust brake, giving outstanding driver
control of rpm and speed — a valuable advantage when
decelerating downhill.
2 6-SPEED MANUAL. This heavy-duty transmission is
standard on all Ram Heavy Duty pickups equipped with the
6.7-liter Cummins Turbo Diesel. The ultralow first gear ratio
— as low as 6.29:1 — is ideal for heavier hauling.
3 5-SPEED 545RFE AUTOMATIC. Standard on 2500
pickups with the 5.7-liter HEMI V8. A specialized fifth
gear — available as an additional overdrive ratio — helps
provide increased fuel economy and reduced engine
noise at highway speeds. (The fifth gear ratio is 0.67:1 —
a 16 percent reduction in engine rpm relative to the
fourth gear 0.75:1 ratio.)

POWERTRAIN/FRAME

THE INCREDIBLE CUMMINS 6.7-LITER TURBO DIESEL. SO POWERFUL, IT DROPS THE COMPETITION
WITH A ONE-TWO-THREE PUNCH OF 650* LB-FT OF TORQUE, 350 HORSEPOWER, AND SQUEAKY-
CLEAN EMISSIONS.
THE CUMMINS®6.7-LITER TURBO DIESEL: A CLEAN BREAK FROM OTHER DIESELS. Cummins and Dodge Ram form a team that results in outstanding reliability. Used
in Ram 2500 up to Ram 5500 Chassis Cabs, the Cummins has total capability with 650 lb-ft* of torque and best-in-class low-end torque.†But a history that starts with
powering more than 1.6 million Dodge Rams also addresses the future. The Cummins 6.7-liter now ranks among the cleanest of any full-size pickup diesel engine.
Emissions are so low, they currently meet 2010 emissions regulations. For more, visit dodge.com/ram_hd *Requires automatic transmission. †Below 1,500 rpm.
1 DURABILITY AND LONGEVITY BY DESIGN. A cast-
iron head, hardened nickel-cobalt steel exhaust valve
seats, gallery-cooled pistons: The materials and
cooling mechanisms are designed to come together
to offer decades of use.
2 FUEL INJECTION AT THE SPEED OF LIGHTNING.
Electronic solenoid injectors are capable of multiple
injections per cycle at pressures up to 23,000 psi.
Result? Precise noise and emissions control with
maximum performance.
3 EXHAUST BRAKE: RIGHT FROM THE GET-GO. It’s
factory-installed, ensuring quality. The engine brake
contributes to longer brake life, faster cab warm-up,
and greater vehicle control.
4 LEAN, MEAN — AND VERY CLEAN. Fewer moving
parts than comparable gas engines reduces
complexity—andconsequentcosts. And thisCummins
is super-clean, making it the cleanest full-size pickup
diesel out there.
5 ULTRA-COOL PERFORMANCE. The gallery-cooled
pistons receive a constant stream of oil for cooler
operation — while the oil itself is simultaneously
cooled by a system of constantly circulating water.
6 SUPER-STRONG CONNECTING RODS. Heavy-
duty commercial-grade connecting rods are forged from
a single mold — a process that adds to strength —
and then fracture-split, for exacting tolerances.
7 BUILT-IN ECONOMIES. The focus on longevity
translates into reduced costs-over-lifetime. The
hardened nickel-chromium exhaust valves also
contribute to long life-to-overhaul range.
8 VARIABLE GEOMETRY TURBOCHARGER (VGT).
Highly sophisticated, the VGT here differs radically
from Ford and GM engineering — which both place
the turbo on top of the engine. Side-mounting of the
turbocharger on this inline six-cylinder simplifies the
design and helps alleviate under-the-hood heat
buildup that can occur with V8 engines.
9 LARGE PISTON BOWL HELPS KEEP THINGS CLEAN.
The large piston bowl isanother engineering technique
used to ensure good power and clean emissions.
• common-rail architecture. Plus. The common-
rail architecture plus sophisticated electronics equals
significant advantages: multiple injection pulses and
independent control of injection pressures. The result
is noticeably quieter operation and outstanding cold
starting capability — down to -20° F, unaided.
• the fuel filter: efficiency by design. With
fuel properties and emissions standards rapidly
changing, the fuel filter offers higher efficiency —
along with the capability to handle ultralow sulfur
diesel (ULSD).
• strong engine, strong warranty. The Limited
Warranty coverage is for 5 years or 100,000 miles.
