Stop cranking by hand. The Lippert Power Stance 3500 (part 813748) is a 12-volt electric tongue jack rated at 3,500 lbs that turns hitching and leveling your travel trailer into a push-button operation. The drop-leg design reaches ground contact fast, the integrated LED work light keeps you visible in the dark, and the bolt-on mounting footprint makes it a straightforward upgrade from any standard A-frame manual or lower-capacity electric jack.
The Power Stance 3500 sits in Lippert's mid-range electric tongue jack lineup -- above basic manual A-frame jacks and below heavy-duty fifth-wheel landing gear systems. It is engineered specifically for travel trailers with A-frame couplers and standard tongue jack mounting footprints. Whether you are upgrading a worn-out factory manual jack or replacing a lower-rated electric unit that struggled with your trailer's tongue weight, the 813748 is sized and rated for the job.
The drop-leg design is the key operational advantage here. The inner leg drops to near-ground level before the screw mechanism engages, which means less motor run time, faster setup, and reduced wear on the drive components compared to a conventional single-travel-tube jack. The motor is 12V DC and draws from your trailer's existing battery or 7-way connector -- no extra wiring runs required in most installations.
Rated for travel trailers with tongue weights up to 3,500 lbs -- handles most mid-size and large TTs without strain.
Inner leg drops to ground contact first, reducing motor travel and speeding up hitch-up and disconnect cycles.
Built-in LED illuminates the hitch area during nighttime hookups -- no separate flashlight required.
Wired to your trailer's 12V battery system. Manual override included for use if power is unavailable.
Unlike a single-travel-tube jack where the motor has to move the full extension distance, the Power Stance 3500 uses a two-stage drop-leg mechanism. The outer housing is bolted to the A-frame. When activated, the inner leg free-drops to near the ground, then the powered screw drive extends the remaining short distance to lift. This means the motor only works for a fraction of the total travel -- faster cycle times, less battery draw per hookup, and longer motor life over thousands of hookup cycles.
The 813748 is designed for travel trailers with A-frame couplers and standard tongue jack bolt patterns. It is a direct bolt-on upgrade from Lippert's own manual tongue jacks and from many OEM electric jacks used on Forest River, Keystone, Heartland, Coachmen, and other major travel trailer brands. Confirm your existing jack's bolt pattern and frame clearance before ordering. The jack ships with mounting hardware; a 7-way connector or direct battery leads are required for 12V power -- both wiring methods are compatible.
The 3,500 lb rating is the lift capacity of the jack mechanism itself. Your trailer's actual tongue weight (typically 10-15% of loaded trailer GVWR) must fall within this limit. A 30,000 lb GVWR trailer could have a tongue weight exceeding 3,500 lbs -- in that case, you need a higher-rated jack. Always verify your trailer's tongue weight before selecting any tongue jack. Do not use this jack to support the trailer for extended maintenance periods without additional blocking under the frame.
