JOST International manufacturers trailer landing gear at our manufacturing facility in Grand Haven, Michigan and over the past 20 years we have supplied millions of sets to our valued OEM partners and their end users.
The difference between the JOST landing gear design and older competitive products is obvious right from the first glance: there is no external gearbox! The gearing mechanism is an integral part of the sturdy leg column, which protects the gearing from abuse and most importantly minimizes significantly water intrusion, which is a very damaging element to landing gear with external gear housings.
Our Magnum design keeps the mechanical advantages offered with the internal gear configuration and adds even more protection against the damage that water and road chemicals create. The gearbox on each leg is completely filled with a premium all weather lubricant- the legs are completely sealed to keep the grease in and everything else out. The elevating screws are completely encased by a grease tube; each time the legs are extended and retracted the screw receives a fresh coating of grease.
