These models require a notch in the ramp for when the engine turns backwards for 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.
CR electronic reverse notched version helixes are NOT for use with aftermarket torsional springs or conversion cap kits! The torsional force will not allow the reverse to engage the notch properly and obvious damage will occur.
