Set of upper and lower a-arms, narrow bottom adjustable spindles, & tie rods. Thease are for the 38/40" front end that is on the ski-doo renegade backcountry, freeride, and several XP summits. Will also work for some of the narrow front end scandic and tundra models with 38/40 front end. Please do your research as I'm not responsible if they do not fit your sled.
