When Ski Doo introduced their own roller secondary clutch, they came out with the QRS secondary.
VENOM SKI-DOO QRS HELIX'S
The helix is the brains of this clutching system and Venom Products offers several different angles to get your machine dialed in.
Venom QRS helixes feature a bushing that meets or exceeds OEM specs and has shown in testing to outlast all other styles of bushings.
If you have increased the load in your system by putting on a longer or deeper lugged track, you need to lower the angle in your helix.
Lower angles slow upshift and give more side pressure for belt traction.
