Product Details: The Jost Standard A400 Series 19" 10-Bolt Landing Gear Leg is the perfect choice for heavy duty applications. The shaft misalignment is avoided and gears are protected by an internal gearbox. The bushings and the cover are sealed to keep moisture out. The 10-Bolt mounting arrangement increases the mounting's rigidity. The double "D" design shaft enables the direct transmission of crank force to the gearbox. The reinforcing strap at the bottom of the upper housing provides added strength. The ductile iron gears that have been austempered won't corrode or wear out. This landing gear leg is the perfect choice for heavy duty applications. FleetPride is your First Click in Heavy Duty®.
