Part Number: 140085 8,000 lb Static Load 15" Lift + 13" Drop Leg Overview This 8,000 lb drop leg trailer jack is a sidewind, heavy-duty jack assembly designed for trailers that need strong tongue support and practical adjustment range. With 15 inches of screw travel plus a 13 inch drop leg, it is especially useful on taller trailers, equipment trailers, utility builds, and other applications where getting the foot close to the ground quickly makes hookup and leveling more efficient. R&P Service Insight On heavier trailers, the drop leg feature is often what separates a frustrating jack setup from a fast, usable one. It cuts down the amount of cranking needed and helps bridge bigger height differences during hookup or parking. Why Drop Leg Matters: The 13 inch drop leg helps you reach the ground faster before using the main lift travel. Heavy Trailer Fit: Strong static support makes this style a solid match for demanding trailer tongue loads. Before Ordering: Verify the side-mount style, outer tube size, bracket fit, and required lift range for your trailer. See It In Action This embedded video gives customers a closer look at the drop leg jack format, operation, and real-world use. The player is built in with rounded corners and autoplay behavior for a more engaging Shopify listing experience. R&P Knowledge Hub Compatibility: Best suited for trailers needing a heavy-duty sidewind jack with drop leg adjustment and a 2-1/4 inch outer tube. Confirm the mounting style and bracket compatibility with your current setup. Vehicle / System Fit: Commonly appropriate for equipment trailers, utility trailers, car haulers, and other heavier trailer applications where extra support capacity and faster setup are valuable. Installation Notes: Verify mount style, tube size, retracted height, total extended height, and available ground clearance before installing. Match the jack to the trailer’s bracket or weld-on arrangement as applicable. Performance Insight: This jack combines 15 inches of lift travel with 13 inches of drop leg travel, reducing crank time while still giving useful adjustment on uneven surfaces or varying coupler heights. R&P Repair Insight Trailer jack replacement usually comes down to three things: capacity, travel, and fit. Buyers often focus on weight rating first, but the real-world success of the swap depends just as much on the jack’s retracted height, outer tube size, and mount compatibility with the trailer frame or existing bracket. Capacity Check: This model is listed with 8,000 lb static load capacity and 5,000 lb lift capacity. Height Check: Retracted height is 25.2 inches and extended height is 53.8 inches, so confirm your trailer has room for the jack to travel correctly. Tube Check: Confirm the 2-1/4 inch outer tube and sidewind configuration match your current jack setup. Features Heavy-Duty 8K Static Capacity Designed to provide strong tongue support for heavier trailer applications where lighter jacks may not be appropriate. Drop Leg for Faster Setup The 13 inch drop leg travel helps close the gap to the ground quickly before fine adjustment with the main screw travel. 15 Inch Main Lift Travel Provides useful working range for coupling, uncoupling, parking, and leveling on trailers with varying tongue heights. Sidewind Operation Sidewind handle layout offers practical crank access on many trailer frames and tongue configurations.
