Jost jacks are one of the most popular two-speed trailer jacks on the market. The patented internal gearbox protects the two-speed mechanism from abuse and water intrusion, a problem that plagues inferior designs.
The gearboxes on Jost two-speed jacks are also completely filled with a premium all-weather lubricant and are totally sealed to keep the grease in and water out. Each time the legs are extended and retracted, the primary screw receives a fresh coating of grease. This design greatly reduces maintenance frequency, which is ideal for high-use trailers.
To change gears, simply slide the handle in or out. The spring-loaded drop leg permits quick retraction once the foot is off the ground, and the high-quality USA made design offers a five-year manufacturer’s warranty.
