TSS or Fixed Strut Length

NOTICE
Install kits are shipped at a set length that is the best all around fit for a specific make and model bike . In some extreme cases a TSS or Fixed strut length can be adjusted to achieve different ride characteristics or handling. Always ensure the TSS has more than 200 PSI while inspecting length. A leaking TSS will ride like the strut is too short.

The bike attitude or pitch should be the same as the stock host bike on wheel. This can be seen by looking at the seat. On a late model motor cross bike, in a typical situation, the seat sits fairly flat.

TIP
It is recommended to ride the snowbike with the factory set length before making any changes. Adjusting fork height and tuning the rear suspension in the skid should be the first approach when dialing in ride characteristics.

  • Strut rod too long: Seat appears to go up in the back, looking like a stink bug. Ride characteristics: feels like the bike is tall in the back, or always putting more weight on the ski. Ski feels like it is heavy and darting.

  • Strut rod too short: Seat appears to go down in the rear at a steep angle. Ride characteristics: feels like the bike is pitched rearward. The ski feels light and washes easily in corners.

To adjust TSS Length while on the bike, follow these steps:

  1. Loosen the jam nut on the trunnion ball joint. These are typical RH threads.

  2. Rotate the shock to the right (if looking down) to shorten, rotate to the left to lengthen.

    TIP
    If there is air pressure in the shock, a wrench will be necessary to rotate. Release air pressure to allow rotation by hand.
    CAUTION
    Pinch points exist when letting out air pressure. Keep hands and fingers clear when letting out air pressure.

  3. When adjusting, adjust in 1 turn increments.

  4. Tighten jam nut when finished.
