Standard Transmission & Gear brings you another option
in performance with Ram Clutches.
RAM Clutch systems for Street/Strip performance cars
offer several alternatives for the proper blend of performance and driveability
for your application.
Premium Replacement Clutch sets
THERE IS A DIFFERENCE! RAM Premium Replacement Clutch sets feature OEM
components used by the vehicle manufacturer when your car was built. You get the
parts that belong in the car, not some low quality or imported replacement
imitation. RAM Premium Replacement sets offer the best level of driveability and
durability for your vehicle. Premium Replacement sets are not intended for
performance or competition use.
HDX Performance Clutch sets GREAT DRIVEABILITY AND PERFORMANCE TO 450
HORSEPOWER The basic RAM concept of clutch performance is simple:
Increased clamp pressure is the single most effective way to manage high
horsepower or load, especially in street driven performance cars. We purpose
build RAM HDX pressure plates with 30% more clamp pressure than stock. The
second important feature is smooth, chatter free operation, which we achieve
with premium organic composite disc friction material. Also, HDX discs feature
our exclusive 8-spring hub assembly for added load capacity. HDX. Great
driveability and control for power levels to 450 horsepower. Sets include
pressure plate, disc, release bearing, and alignment tool unless otherwise
noted.
Powergrip Performance Clutch sets MUSCLE CAR PERFORMANCE TO 550 HORSEPOWER As power levels move up to and beyond 500 horsepower.
RAM POWERGRIP meets the challenge with a combination of organic and metallic
disc friction surfaces that effectively increase the clutch capacity to the 550
horsepower level. The 8-spring hub is equipped with RAM POLYCOIL damper springs
encapsulated in polyurethane. This spring can handle three times the shock load
of just the coil spring, and is standard in all RAM competition discs. The RAM
Competition pressure plate in this kit provides 30% more clamp pressure than
stock, and meets SFI specifications. At this high level of performance RAM
POWERGRIP provides surprisingly good driving characteristics with smooth,
comfortable driver control. Sets include pressure plate, disc, release bearing,
and alignment tool unless otherwise noted.
Powergrip HD Clutch sets STREET AND COMPETITION PERFORMANCE TO 650
HORSEPOWER Powergrip HD is a true "strip/street" competition
clutch system that can handle the rigors of weekend racing and spirited street
driving. This system has the same components as standard POWERGRIP above with
the exception that the disc friction surfaces are both sintered iron. Sintered
iron provides a degree of slippage on vehicle launch to prevent the violent and
uncontrollable engagement characteristics of paddle type metallic discs. This
firm consistent engagement is easy to control. Some chatter is likely on
engagement with rear gearing less than 3.73 in street applications. Each set
includes the pressure plate, clutch disc, release bearing, and alignment tool
unless otherwise noted. Use Powergrip HD for power levels to 650 horsepower, or
lower powered vehicles that see frequent track duty.
Street Dual Clutch Systems THE BEST OF BOTH WORLDS You were told, "you can't have your cake and eat it
too". THAT'S NO LONGER TRUE FOR PERFORMANCE CLUTCHES. The RAM Street Dual
affords perfectly smooth engagement for street driving yet handles horsepower
levels in excess of 1000! The premise of the Street Dual is driveability for
yesterday and today's muscle cars. Street Dual units use our 300 series steel
backed friction discs in a sprung hub top/solid hub bottom arrangement. The
sprung clutch disc features an eight-spring hub assembly with urethane
encapsulated springs for added durability, and a marcel spring that helps
eliminate the 'on/off' switch operation of most dual disc clutches. The floater
plate drives from six stands, three of which are composite to help reduce
floater plate noise. For severe duty applications, 6 steel stands are
recommended. A billet aluminum flywheel rounds out the package that weighs in at
an average of 45 pounds.
True Balance Billet Flywheels DON'T COMPROMISE ON SAFETY AND PERFORMANCE All billet flywheels are not created equal! Make sure
you are getting the features you pay for. RAM billet steel and aluminum
flywheels are fully machined and assembled in house. That means when you get
your RAM billet flywheel, it is already surface ground, already balanced, and
ready to install out of the box. A key feature of RAM aluminum flywheels is the
steel insert. A flywheel insert must have enough mass to wick heat away from the
clutch without distorting. RAM uses a .250-inch thick inset that is riveted in
before the flywheel is surface ground. This assures a parallel friction surface
with no run out, and enough material to adequately wick the heat while
maintaining flatness over time that thinner inserts simply cannot do. All RAM
billet flywheels are SFI certified.
