Buyer’s Guide: What to Consider

When choosing a side mount trailer jack, consider lift capacity, mounting type, vertical travel, swivel functionality, and compatibility with your trailer. These factors ensure you get a jack that fits your needs and installs easily.

• Lift Capacity: Choose a jack with a lift capacity that exceeds your trailer's tongue weight. Most side mount jacks range from 2,000 to 5,000 lbs support.
• Mounting Type: Decide between bolt-on or weld-on. Bolt-on kits are easier to install, while weld-on offers a permanent, secure fit for heavy loads.
• Vertical Travel: Consider the lift range. More travel (e.g., 15 inches) helps on uneven ground, while shorter travel may suffice for level surfaces.
• Swivel vs. Fixed: Swivel jacks can be rotated out of the way for towing, improving ground clearance. Fixed jacks are simpler but may not offer the same flexibility.
• Compatibility: Ensure the jack or relocation kit fits your trailer's frame size and jack bolt pattern. Most kits fit 3-bolt A-frame jacks on 2-3.6 inch tubes.

Conclusion

Choosing the right side mount trailer jack depends on your trailer’s weight and your installation preferences. For a direct swivel replacement, the Curt 28302 offers reliable strength. If you need a versatile bolt-on swivel with long travel, the VEVOR is a great choice. For relocating an existing jack, the Yuleimy and Demimy kits provide easy, no-weld solutions. The NBJINGYI is ideal for heavy-duty applications requiring a weld-on swivel.

Consider your trailer’s tongue weight, frame size, and whether you prefer bolt-on or weld-on installation. Any of these options will improve tailgate access and towing clearance, making your trailer experience much more convenient.
