This is the In The Ditch X-Series SLX dolly set with speed lube spindle. These In The Ditch tow dollies hold up well against road grime, while the lightweight aluminum axle and ergonomic handle make it simple to maneuver on the recovery site. Bolt-on spindles are easy to replace with basic hand tools, and the speed-lube design (SLX) makes packing bearings effortless with a center grease work on this assembly. These dollies feature best in class capacity, and are available in powder coat black or zinc plated finish. They are also available with a tire size of 4.80 or 5.70.
