Dalton produces Billet CNC machined helixes for the QRS secondary clutch found on the 08 + XP/XR chassis from Ski-Doo. Many straight and multi angle cuts available. Angle geometry is the same as factory for easy comparison and tuning. These helixes are designated by the prefix "Q". All current Dalton versions also contain the extra hole required for the latest torsion tang locations from 4 stroke model factory spring updates.
A Dalton helix does have the factory curved floor spring seat groove for the factory plastic spring slide cushion (like the factory 2 stroke version) so everything works like factory when you move the plastic to the new helix.
