Dual wheels provide a stable ride for your VOModular 6T, VOLight 8T, or VOLight 10T boat versus single wheel designs. Most of the weight rides on the wheels and the foot rests are used to guide the boat to/from the launching site. The kit can be left installed both in the water and in the vehicle. Axle and connector tubing are aircraft alloy aluminum with hammertone gray finish. Kit includes an extra clevis pin to secure the oar blades together during transport.
