This is R1 Wurks’ flagship product, the DC1 drag car is a top of the line race car. This kit has been tested and proven on the track and its winning reputation speaks for itself. There are two kit options to choose from, either kit #1 which includes the US Made V1 shock kit which has more spring options, or kit #2 which includes R1’s V2 shock kit. Also you have a choice between our aluminium standup transmission or the B6.3 plastic laydown transmission. There is no price difference between these last two options. These kits do not include shock oil, diff oil, wheels, tires, electronics or a body.
