Arctic Cat Wildcat XX PTO Output Shaft

Our new PTO Output Shaft is a higher quality part built with tighter tolerances to cut down on the noise in the cab, and it reduces the vibrations and harmonics that lead to clutch button fatigue and failure. Also Available Assembled with Bearing and Seal!

We have found that a vast majority of the cab noise if coming from the clutch area.  The primary source of the excess noise has been traced down to crankshaft PTO output shaft. This is a bolt-on part with internal splines that mate to external splines on the crankshaft, and the stock shaft has excessive tolerances that cause extra noise, vibration, and harmonics.  Our output shaft is a higher quality part built with tighter tolerances to cut down on the noise, and it reduces the vibrations and harmonics that lead to clutch button fatigue and failure.

Sound level reduction at shoulder level in the cab with the Speedwerx PTO shaft- 

1500 RPM:  -4dB or 37% reduction
2500 RPM:  -5dB or 44% reduction
4500 RPM:  -1dB or 11% reduction (wind noise has an effect on the dB meter at this speed)

Speedwerx PTO Output Shaft Combined With Clutch Intake Kit-

1500 RPM: -5dB or 44% reduction
2500 RPM: -6dB or 50 % reduction
4500 RPM: -2 dB or 21% reduction (wind noise has an effect at this speed)

NOTE: Sound Pressure Level as measured on an Electronic Decibel Meter is not a linear scale- 6db lower represents a 50% reduction in the sound pressure level. Likewise, a 6dB increase represents a 100% increase or doubling of the sound pressure level.
