HELIXES PROGRESSIVE "C" TYPE FOR ARCTIC CAT ACT DRIVE

With electronic reverse system.
Some 2009-2011 Arctic 2-stroke models have the electronic reverse system and require a notch in the ramp for the reverse. These are still the earlier style adjustable “C” helix models that require a DHC-100 cover kit, or a '05 type Arctic adjustable cover and hardware to use on the newer sleds that came with a cast one-piece helix. All models with the notch for electronic reverse system are designated “CR” followed by the angle. If it is a progressive type cut, it would be designated by the suffix “P” after the part number.
