"S" Series helix for Ski-Doo:
Dalton’s helixes for the Ski-Doo DSA models feature a stainless steel hub, closer tolerances, better corrosion resistance and a hard coated outer surface. Note: These models for the DSA (non-RER) secondary clutch are designated by the letter “S” before the angle number. Ex: S 52 / 48.
"HR" Series helix for Ski-Doo:
Roller Clutch Electronic Reverse Helixes. These helixes fit Ski-Doo models that have the 05-07 roller secondary clutch and electronic reverse like the Rev-”X” models and the 1000 cc twin cylinder models. These are for the roller clutch only.
"Q" Series helix for Ski-Doo:
Dalton now produces Billet CNC machined helixes for the new QRS secondary clutch found on the new 08 XP chassis from Ski-Doo. Many straight and multi angle cuts available. Angle geometry is the same as factory for easy comparison and tuning. These XP model helixes are designated by the prefix “Q”.
"RS" Series helix for Ski-Doo:
RER Helix (Electronic Reverse) for 03-06 button, non-roller clutch only. These helixes fit many of the electronic reverse models like the popular REV platform. Now even more angles to choose from. Note: These model helixes designated by the letters “RS” before the angle from the part number, ex.: RS 46 / 42. These helixes do not fit models with the newer roller clutch like the REV “X” package models.
