Buying Guide
What load capacity do you need?
Choose a jack with a dynamic load rating at or above your trailer’s weight plus tongue weight. Heavier trailers benefit from 5000–7500 lbs capacity.
What lift range is required?
Assess the minimum and maximum height you need. A longer lift range helps on uneven ground and multi-vehicle setups.
What mounting and compatibility matter?
Check frame dimensions, mounting hole locations, and whether a 2- or 3-bolt pattern fits your trailer. Some jacks include 90° mounting holes to avoid tailgate interference.
What weather and durability features are valuable?
Look for weatherproof covers, rust resistance, and protective coatings for outdoor use. A built-in circuit breaker provides additional electrical safety.
Is plug-and-play or wiring complexity a concern?
Some models offer 7-Way plugs for simple wiring, while others require more involved electrical connections. Consider whether you prefer a ready-to-wire solution.
How important is speed and ease of use?
Higher lift speeds and smooth ball-screw or low-friction designs improve daily use, especially for frequent hitching and leveling tasks.
