FOX 1.5 QS3 track kits are the next generation of mountain sled suspension technology. QS3 allows you to adjust the compression damping with ease to suit the conditions. Three positions keep the adjustments simple, and can easily be adjusted with gloves on. 

The rear track now offers a true lockout setting, QSL, allowing riders to fully lock out at a flick of a switch. This kit is tuned in partnership with Chris Burandt. Ride harder in the back country with less fatigue, without compromising durability. Experience a new sense of control.
