Exedy racing and performance clutches are engineered,
designed and built from the ground up as racing clutches,
not rebuilt from stock clutches that have been modifed.
of Exedy pressure plate castings are made from ductile
(nodular anti-burst) iron for your safety. None of
Exedy pressure plates are made of grey cast iron as
are many stock pressure plates that are rebuilt in
to "performance clutches". Beware, cheap
grey iron rebuilt pressure plate castings may explode,
unlike nodular iron.
Single Plate Organic Racing Clutch
Racing clutches with organic friction materials use
only premium friction materials that are resistant
to slippage and burst. Increased clamp loads give
the necessary capacity to handle modifed engines.
Organic friction material clutch is the preferred
clutch for street and light horse power track.
driveability will be like a stock clutch. Pedal efforts
will be slightly higher because of the higher clamp
loads. All of Exedy clutch discs have high capacity
spring center dampers to reduce the drive train shock
Single Plate Cerametallic Racing Clutch
cerametallic clutches are designed to handle the abuse
of high power modified engines. Cerametallic friction
maerial can handle much more slippage that stock type
disc assemblies without slipping and fading. All Exedy
cerametallic discs have spring center dampers to reduce
the impact and shock loads put into the drivetrain.
This protects the transmission and the rest of the
drive line system.
any cerametallic clutch system, there will be some
compromise of start up driveability as compared to
a stock clutch (chatter on light throttle, low rpm
start up). This characteristic is generally felt to
be acceptable in modified performance cars.
Hyper Single Racing Clutch
Hyper Single Clutches come with lightweight steel
flywheel and a 6-puck cerametallic facing, spring
center damper disc assembly. The disc is generally
smaller and thinner than the OEM disc making for lower
inertia and therefore quicker, easier shifting and
less wear and tear on the transmission synchroes.
The higher clamp load and cerametallic friction facings
give approximately twice the holding torque of the
OEM clutch and generally higher than other single
with all cerametallic clutches, the street drivability
may be marginal due to chattering and harsh engagement
characteristics. Approximate HP capacity is up to
Multi-Plate Racing Clutch
high-powered applications, Exedy offers twin and triple
Multi-Plate Clutches. These are designed for hot street
action as well as drag, road, and rally racing.
Twin-Plate clutches are rated for above 500hp to 705hp.
The Triple-Plate clutches are rated for up to and
over 1000hp (for drag race applications). Twins come
with both spring damper discs (SD type) and solid
discs (SR type). Triples are all solid discs.
multi-plate clutches come with a lightweight, chromoly
steel flywheel and the famous puple anodized forged
aluminum clutch cover.
