KYX Electric Trailer Jack 5000 lb Capacity with Waterproof Cover — 12V, 9–32 in Adjustable

The KYX Electric Trailer Jack is a 12V, 5000-pound capacity powered tongue jack with a waterproof cover and manual crank backup for safe, fast trailer raising and lowering.

Designed for trailers, RVs, and utility haulers, the KYX electric jack replaces manual lifting with a durable, weather-resistant motorized unit. Constructed from carbon steel with an anti-rust finish and built-in overload protection, it delivers dependable performance on campsites, job sites, and long hauls. The unit adjusts from 9" retracted to 32" extended, includes a waterproof cover to protect electronics, and accepts a hand crank if power is unavailable.

How much weight can this jack handle and is it safe to use?

The KYX jack is rated to lift up to 5,000 pounds, making it suitable for most mid-sized trailers and many RVs. Safety features reduce the chance of motor damage and unexpected shutdowns during heavy use.

• 12V DC motor with 5,000 lb lifting capacity
• Internal overload protection that cuts power if the motor overheats
• Manual hand-crank included for power outages or emergencies
• Stable A-frame mounting pattern compatible with common trailer tongues

What materials and weather protection does the KYX jack offer?

This jack uses carbon steel construction with an anti-corrosion coating to resist road grime, rain, and salt spray. A waterproof cover shields the motor and electrical connections to extend service life in wet conditions.

• Carbon steel body with anti-rust coating
• Sealed electrical housing and waterproof protective cover included
• Durable finish resists chipping and corrosion from outdoor exposure
• Designed for repeated outdoor use and seasonal storage

How does the height adjustment work and what are the dimensions?

The unit has a telescoping shaft that lets you set the trailer height precisely between 9" retracted and 32" fully extended. Multi-level adjustment keeps trailers level across uneven ground and simplifies hitching and unhitching.

• Retracted height: 9" for compact storage
• Maximum extended height: 32" for clearance and leveling
• Multi-position holes for fine height tuning
• Mounts to standard A-frame tongues for easy installation

What if I lose power or need to install this myself?

KYX includes a manual crank so you can operate the jack if the vehicle battery is disconnected or depleted. Installation is straightforward with common tools and standard trailer mounting patterns; basic wiring to a 12V source completes the setup.

• Hand-crank override for power-loss scenarios
• Simple bolt-on installation to A-frame tongues
• Wiring harness designed for 12V trailer battery connections
• Clearances and mounting holes follow typical trailer jack dimensions

Who is this for: The KYX Electric Trailer Jack is made for trailer owners who want faster, safer hitching and leveling—campers, RV owners, landscapers, horse trailer operators, and tradespeople hauling equipment. It suits anyone replacing a worn manual jack or upgrading to electric convenience, especially users who need a weather-resistant, heavy-duty unit with a manual backup.
