POLESTAR Electric Trailer Jack 7500 lb A-Frame — Weather-Resistant, Built-In LEDs & Waterproof Cover

Whether you tow a boat, RV, horse trailer or equipment hauler, the POLESTAR electric trailer jack delivers high-capacity lifting and dependable operation in harsh conditions. Engineered with an advanced ball-screw (thread friction) mechanism and a rugged motor, this jack simplifies hitching and leveling so one person can manage large trailers without hand cranking. It includes practical features such as integrated LEDs for night hookups, a waterproof rain cover, and an automatic circuit breaker for added safety.

How much weight can this jack lift and support reliably?

The POLESTAR jack is rated to dynamically support trailers up to 7,500 pounds and offers static lifting capacity up to 10,000 pounds, giving a wide safety margin for most travel trailers and utility trailers. Its brake motor and ball-screw design maintain steady, controlled movement under load.

• Dynamic capacity: 7,500 lbs for routine hitching and towing prep
• Static lift strength: up to 10,000 lbs for short-term support
• Powerful motor with integrated brake for smooth, stable operation

What features make it durable outdoors and easy to use?

Materials and protective design keep the jack working through rain, sun and dirt. A waterproof cover guards the electrical components and the built-in circuit breaker trips and resets automatically if the motor draws excessive current. The ball-screw mechanism reduces wear and improves lift efficiency compared with older worm-gear jacks.

• Weather-resistant construction plus waterproof rain cover for electronics
• Auto-reset circuit breaker protects motor from overloads
• High-precision thread-friction (ball-screw) for smoother lifting and longer life

How far does the jack extend and how does it help during low or uneven setups?

This A-frame jack offers a versatile lift range that covers most towing needs. Retracted height starts around 9 inches and extends to 27 inches, with an additional 4.5-inch drop leg option to reach approximately 31.5 inches total—making hitching easier on uneven ground and low trailers.

• Standard lift range: 9" retracted to 27" extended
• Optional drop leg adds 4.5" for about 31.5" total extension
• Built-in LEDs illuminate ball and coupler for nighttime hookups

How does installation and daily operation work for most trailer owners?

Installation is straightforward for A-frame couplers and uses standard mounting points; wiring connects to the trailer battery for power. Operating is simple: press the up or down switch on the motor housing to raise or lower the tongue, and the brake motor holds the load when stopped, eliminating slipping or sudden drops.

• Mounts to standard A-frame tongue with common bolt patterns
• 12V power connection to trailer battery; straightforward wiring
• Push-button control with brake motor for secure positioning
