PROGRESSIVE cut helixes for the 2005 ACT Drive. (tubular type)*

The regular helixes for ACT Drive from the factory, as well as our “C” listing are done with a distinct step style of cut, using a short duration first angle. Some drag racers prefer a full progressive curve. The following with this style of cut are designated by the prefix “C” and the suffix “P”.

Note: This is a tubular type helix for pre- 2006 ACT Drive models. When used on a later (2006-2011) version ACT diamond drive secondary it requires the use of the DHC-100 cover, or the cap and assembly parts from a 2005 Arctic Cat model.
