GUNIWHEEL™ IS A REVOLUTIONARY SOLUTION WHY USE GUNIWHEEL™ ? = Jack stands can be unstable, unsafe, and may cause damage to the vehicle undercarriage if not positioned properly. = Jack stands limit the mobility of a vehicle during repairs and services. = GUNIWHEEL™ increases service and repair ratios by allowing mobility to vehicles in the repair phase. = Install a GUNIWHEEL™ instead of car wheels during long-term storage on your boat trailers, campers and vehicles to avoid flat spots and dry outs on side walls during the storage period.
