Hunter Engineering's RKHD Heavy-Duty Power Rack now includes longer approach ramps and a redesigned rub rail system to create more clearance to easily accommodate lower and longer vehicles. The standard RKHD configuration is 24 inches in height and includes a turnplate section, four runway sections and a pop-up ramp per side. Additional runway sections can be added for unlimited wheelbase capacity. The RKHD can also be installed in shallow-pit configurations of 24-inch or 30-inch depths.
