RAM VDS Clutch Systems

In drag
racing, the clutch acts as the traction control device for the car. The
clutch system applies stored energy to the rear wheels during the launch.
To obtain optimum clutch performance, you must have enough flywheel
inertia to get the car moving and enough clutch clamping pressure to
accelerate the vehicle without spinning the tires. To achieve consistency,
the clutch pressure must remain constant over time, allowing the car to
perform to maximum potential. The RAM VDS system is the only diaphragm
clutch that allows you to set up and maintain the clutch pressure.
VDS clutch systems come from the factory with either steel or aluminum
flywheels, and include the RAM 300 series organic disc. 300 series discs
feature our eight spring hub with urethane encapsulated springs, and steel
backed organic facings. The VDS system can be upgraded with either the 900
series sintered iron or 6000 series bronze metallic discs through your RAM
dealer.
There are several key features of the RAM VDS clutch system. The clutch is
set up with maximum clamp pressure from the factory. Stock and aftermarket
pressure plates are set up so that the maximum plate load occurs after the
clutch begins to wear. RAM VDS is designed so that the clutch pressure can
be restored as the clutch disc wears; oem and other aftermarket units lose
pressure as wear occurs. The VDS clutch pressure can also be reduced if
the application dictates less pressure is necessary to control tire spin
at launch.

The VDS clutch
system is designed to be user serviceable in the field. Both the pressure
plate and the steel insert on aluminum flywheels are replaceable.
Combining this with a new RAM clutch disc makes rebuilding your clutch a
snap!
All RAM VDS clutches are SFI certified for competition in vehicles running
11.99 or quicker in the quarter mile. Because the VDS system is designed
for racing use, it is sold without warranty. |
