Trailer Parts Pro 5,000 lb A-Frame Trailer Jack Top Wind, 15" Lift, 10" Bracket Height (SKU: JP03-030)

The Trailer Parts Pro JP03-030 is a 5,000 lb capacity A-Frame trailer jack built for medium-duty trailers including enclosed cargo trailers, equipment trailers, and larger utility trailers. The top wind handle provides smooth, horizontal cranking operation, and the jack delivers a full 15 inches of lift travel with a 10-inch bracket height to fit a wide range of A-frame coupler bodies.

Engineered with ACME threaded screw and nut for smooth, precise lifting, an ergonomic handle design for reduced hand fatigue, and a high-grade outdoor powdercoat paint finish to protect against corrosion, road salt, and UV exposure. Thicker steel tubes and a reinforced inner screw shaft make this jack more durable and stable than standard OEM alternatives.
