Features and Specifications
The multi-ply treads have an aggressive black rubber all-terrain 4" wide pattern. The inside of the tracks have a internal cleat that is used for positive timing to match the CNC manufactured HD2 wheels. The tracks have UHMW tapered guides screwed into the side that are matched with the taper on our generation 4 wheels. This allows for better tracking and very low probability of derailing. The track does NOT have a splice! Its continuous. The nominal center to center distance of these tracks with the HD2 wheels is 28.375". The weight of each track is ~5lbs.
