Why spend so many $$$$ on an electric/hydraulic jack? Kwick Kranker is all you need!. You probably already have a 1/2" cordless drill. Why buy an electric/hydraulic trailer jack, batteries, wiring and maintenance when your electric drill can raise and lower existing manual trailer jacks 7 inches in less than 10 seconds. Kwick Kranker is portable and will lift multiple goosenecks, horse trailers, semi-trailers, flatbeds, dumpers, stock trailers, etc.. Kwick Kranker has a lifetime warranty. Made from stainless steel and aluminum in the USA by veteran owned company.
