For those of you looking for a little shorter version of the Challenger X3, we have a limited number of 156" and 162" Challenger X 2.7 tracks. These are the X3 trimmed to 2.7" lug height by Camso. When these are gone, we will be trimming in house for those of you who want for a little more clearance and a slightly stiffer version of the X3. Center port and solid center belt options. All 3.0" pitch.
