You are at the point where the clutch on your Dodge Ram Cummins Turbo Diesel has worn out and
you're looking at your options. You may have modified the engine/exhaust
or added a chip to increase horsepower. Perhaps you tend to tow a lot of heavy
loads and need something that won't slip in the higher gears? You've seen
a lot of different options from several different companies and have gotten
a lot of different advice from different sources. Get's a little confusing, doesn't it?
We created the following article with links to the different
model years in hopes that it can help you make an informed decision. Please
do not hesitate to call us if you would like us to make a recommendation
based on your truck and its' intended use.

Ram Series Cummins Turbo Diesel
(May 2005 - 2009 with a Dual Mass Flywheel)
From
May 2005 to 2009, Dodge redesigned the Ram Series Cummins Diesel clutch
to utilize a Dual Mass Flywheel. This was a due to Mercedes-Benz influence,
resulting in the Ram Series Cummins Diesel being fitted with their G56
Transmission. This change in clutch design was to make the truck
drive more like a car. The problem with the Dual Mass Flywheel in this
pickup is that it is limited by the OE engine torque capacity (ETC) and would tend
to wear out in a very short period of time - often less than 40K miles.
In a direct response to the failure rate of the Dual Mass Flywheel, Valeo,
the original OE manufacturer, engineered a Solid Flywheel Conversion Kit. The Solid
Flywheel Conversion kit quickly became very popular with truck owners
and also allowed for flexibility in engineering clutch options with increased
torque. Beginning 2007, Dodge made the 6.7L (408") Cummins Turbo Diesel
as available engine option.
Quick
Note: The only downside to converting to a Solid Flywheel is
that the engine vibration that diesels tend to produce no longer gets
absorbed by the flywheel. The engine vibration is transferred to the transmission
and causes "gear rattle". This is only noticeable when the truck
is at a stop, in neutral, with the clutch pedal out. As soon as the clutch
pedal is applied, the vibration goes away. This is a normal occurrence when doing a solid flywheel conversion. It does not increase gear wear and can be safely ignored.

Ram Series Cummins Turbo Diesel
(1994 - April 2005)
In
1994 Dodge discontinued the D-W Series pickups and introduced the
Ram Series 5.9L (359") Cummins Turbo Diesel Pickup (Ram 2500, Ram
3500, and Ram 4500) to take their place. From 1994 to April 2005, the
OE clutch setup utilized a solid flywheel, which can be replaced or resurfaced. From 1994 to 1998, the Ram Series came standard with a
New Venture NV4500HD 5 Speed transmission which uses a 12¼' clutch.
From 1999 to April 2005, Dodge introduced the New Venture NV5600 6
speed transmission option. The 6 speed option was fitted with a 13"
clutch which increased the torque from 450 lb-ft. (for the 5 speed
transmission) to 600 lb-ft.

D-Series (2WD) / W-Series (4WD) Cummins Turbo Diesel
(1988
- 1993)
From 1988 to 1993 the Dodge Pickup fitted with the 5.9L (359") Cummins
Turbo Diesel engine had the designations of D-Series and W-Series Pickups.
The D-Series (D2500, D3500, and D4500) is a 2 wheel drive (RWD) pickup and the
W-Series (W2500, W3500, and W4500) is a 4 wheel drive (4WD) pickup.
The D and W Series pickup came standard with a hefty 13"cast iron clutch.
LuK took note of the longer shift times of the heavy 13" cast iron
clutch and subsequently designed a less expensive 12¼" stamped steel
clutch that bolts to the existing flywheel without modifications and
achieves identical torque (450 lb-ft.) as the original 13"clutch. While
the 13" cast iron clutch is still available, the stamped steel version
has gained the greater market share for these model years. The LuK design
also allowed aftermarket manufacturing companies flexibility in engineering
clutches for increased torque applications.
