03 / Know your tunnel

Short tunnelor full tunnel?

Tunnel shorter than track

Short tunnel

The tunnel runs about 8 to 10" shorter than the track. A 146" short-tunnel sled has a 137" tunnel; a 154" has a 146".

  • Summit X & X Expert, 2020 and newer
  • Summit Adrenaline & Edge
  • Freeride, 2021 and newer
Tunnel matches track

Full tunnel

The tunnel is as long as the track. A 146" full-tunnel sled has a 146" tunnel, so every product fits.

  • Summit SP
  • Backcountry
  • Summit X, 2017 to 2019
  • Freeride, 2018 to 2020
Good to know

Before you order

  • LinQ bases required. Everything mounts to the LinQ bases on your tunnel. The SkiPorter Pro needs 4 bases (not included).
  • 2017 and 2018. In 2017 only the 850 E-TEC models are on the Gen4 chassis, and 2018 MXZ and Renegade 4-strokes are on an older one. Running one of those? Ask us.
  • 2-up sleds. On a Skandic, Tundra or Grand Touring, fit depends on your seat and rack setup. We'll confirm before you order.

Still not sure?

Send us your year, model and track length. We'll confirm fit before you order.
