M20 Airwave Suspension
The M-20 AIRWAVE snowmobile suspension simply eats ugly trails up! You know the ones…harsh stutters leading into pounded out moguls followed by unending chop. The M-20 snowmobile suspension swallows up the big stuff while quietly filtering out practically all medium through small bumps. The broadness of its effective range is more than surprising. Once the simple air adjustments are made the rear of your sled becomes extremely compliant yet ideally controlled. It resists bottoming in the toughest trail situations. No other production or aftermarket suspension can begin to deliver this kind of breadth in its operating range. If you tune a production snowmobile suspension for big bumps, then they’re stiff in the medium and small. If they are calibrated in the middle then their ride falls short on each end.
For the M-20 snowmobile suspension to be this capable, we engineered every physical advantage into it we could. In the rear its trick Assault Big Shaft shock is designed to asymmetrically dampen while its huge volume AIR-SPRING is being displaced over 8 inches. This large spring displacement provides for low air pressure and softness during small bump-low energy events while delivering the firmness required in stopping bottoming of high energy big bump events.
In front our large volume Assault FT Air-Shock improves ride quality in low to mid range bumps and increases the M-20’s capacity in handling square edged high energy bumps as encountered on rough trails, ditch banging or XC racing.
Topping off the list of ride improving advances is the Diamond Option. This choice combines an onboard air-compressor with a switching system that delivers fast and easy finger tip control. This is our best suspension package and we are very proud of it.
We so believe that this unit will meet your bump eating expectation that we’ve back it with a money back guarantee!
