Rugged Construction

Air Spring... the convoluted air springs have actually been used for many years as shock and vibration dampers on trucks, buses and heavy equipment. Subject to tremendous loads, these springs cycle hundreds of thousands of times with virtually no maintenance and proven reliability.

Internal Stabilizer... at the center of the jack is the internal stabilizer system made from ASTM-513 steel dom tubing. Fully machined to strict tolerances this system provides lateral and vertical stability. Calculated clearances between the members allow for flexibility during the lifting arc.

Pressure Relief Valve... designed to prevent over-inflation, the pressure relief valve Zendex has selected is a top quality certified valve which is factory tested and set to release air if pressure exceeds setting.

Air Control Valve... precision machining, brass components, Teflon seals and a positive air lock design insure many years of trouble free use and the ultimate feather control.

Jack Pad... adjustable top swivels 360 degrees for easy grab of vehicle jack points.

Convenient Handles... the handles are located both front and rear for maximum flexibility during use as well as transport.

Finish... powder coating, zinc and chrome plating along with the use of aluminum and brass are all part of Zendex Tool's design to provide the best quality, longest lasting and finest looking products we can.

Testing... every RakJak™ we make goes through a comprehensive testing procedure prior to shipping. Included are air leak tests, pressure relief function, mechanical action, finish and lubrication.
