Off-roading kit with Pneumatic tires designed for the SunCase™ 3651 to optimize off-road transportation and performance. The big wheel kit is an add on “after production” wheel kit providing users with the ability to move the larger SunCase™ overland, over uneven terrain. The large tires provide a smooth ride. Perfect for location shoots for film and tv, military users in vehicle dismounted situations, for emergency managers looking to deploy in areas after disasters and for remote users needing to access hard to reach locations. As the 3651 weighs in at 126lbs, this is a great addition.
