Clutches

Aggressor 6×6 clutches use compression springs connected to the pressure plate.

Advantages:

• The spring material accommodates higher temperatures; consequently, springs last much longer.
• The six compression springs are factory-matched for uniform pressure which minimizes chatter and eliminates the cost of “blueprinting”.
• The springs are accurately adjusted without a depth micrometer. Saves time and aggravation.
• The adjustment screws have “stops” to prevent coil bind and spring damage.
• The levers have fixed pins. Levers remain centered in their slots when the clutch is spinning.
• Friction material and plate surface finish are factory optimized for best performance. DO NOT BLUEPRINT.
• Discs can be easily removed and cleaned without disassembling the springs, levers and pressure plate. (Clean discs are faster.)

Vortex clutches use torsion springs connected to the levers.

Advantages:

• Vortex clutches react more quickly to engine “bogging” improves acceleration.
• Torsion springs are simple and fast to adjust.
• Torsion springs do not use height measurements.
• Torsion springs are exceptionally less sensitive to air-gap. More laps before replacing discs.
• Vortex clutches lockup very smoothly.

Configurations:

• Vortex Clutches come in one, two, or three-disc variations.
• The hub bore (crankshaft diameter) is ¾ inch only.
• #35, #219 sprockets and 8mm pulleys are available.
• The sprockets employ a ball bearing, needle bearing, or bronze bushing depending on sprocket style, and tooth count.
• All pulleys use double-row ball bearings.
• Sprockets and pulleys are sold separately.
