CROWER CLUTCHES
Since their inception in 1966, Crower clutches have been regarded as the ultimate solution to high horsepower, high torque, and power to ground control. There is no other clutch available on the market that can harness the extreme power output of a competition engine and control it as accurately and consistently as a genuine Crower clutch. Our ongoing trackside research and development program insures you have the latest and most innovative components available.
 THE “CROWERGLIDE”
The most copied clutch in racing, the original “CROWERGLIDE” incorporates a completely centrifugal design and is totally adjustable. It was the industries first real slipper clutch, which is why it is so prevalent in racing today.  Crowerglides are available for a wide variety of applications including: • Truck and Tractor Pulling • Drag Racing • Sand Drags• Monster Trucks• Mud Racing
CROWER PEDAL CLUTCHES
Unlike the completely centrifugal “CROWERGLIDE”, the Crower pedal clutch offers the conventional style foot control launch combined with centrifugal assistance and static spring adjustment. This highly versatile Crower clutch is available in an assortment of centrifugal lever and static spring combinations to suit the following applications:• Alcohol Dragster & Funny Car • Pro Modified • Comp Eliminator• Sand Dragsters • Truck & Tractor Pulling
