(888) 312-8812 Login SignupThe Jost Trailer Jack Crank Handle provides the manual control used to raise or lower trailer landing gear during coupling or parking procedures. Rotating the crank turns the internal jack mechanism, allowing the landing legs to move vertically. This motion adjusts trailer height so the kingpin aligns correctly with the tractor fifth wheel during hookup. The fold-away handle position keeps the crank close to the jack assembly while the vehicle is moving. Mounted along the landing gear gearbox, the Jost C10591.2 enables controlled operation of the trailer jack drive system.
