JY PERFORMANCE Trailer Gate Lift Assist for Open Utility Trailers — Two-Sided Gas Springs, 300 lb Capacity

The JY PERFORMANCE Trailer Gate Lift Assist is a two-sided gas-spring style support system that makes open utility trailer tailgates and ramps nearly weightless for safer, smoother lifting and lowering.

If you regularly load and unload cargo from an open utility trailer, bending and wrestling a heavy tailgate becomes a hassle and safety risk. This lift assist kit is engineered to distribute force across both sides of the gate to reduce wear, prevent binding, and make manual operation effortless. It fits most open utility trailers that have 12"–24" side rails and tailgates or ramps between 4' and 6' tall. Constructed from powder-coated steel and rated for up to 300 lb of assistance, the system ships with wire rope, mounting hardware, and illustrated installation guidance.

How does the two-sided design protect my trailer gate?

The dual-side configuration applies lifting force evenly so one side isn’t overloaded during use. That balance reduces twisting and uneven hinge wear, helping the tailgate and frame maintain alignment over time. The result is fewer repairs, smoother operation, and a longer usable life for both gate and trailer.

• Equalized load distribution across both hinge points
• Reduces asymmetric stress and metal fatigue
• Helps prevent gate sag and hinge deformation

Will this lift assist fit my trailer and how is it installed?

It’s compatible with most open trailers that have side rails measuring 12"–24" and tailgates or ramps 4'–6' in height. Installation requires drilling for mounting brackets; the kit includes 59.06" wire rope, mounting hardware, and step-by-step instructions. With basic tools and an assistant for alignment, many users complete installation in one to two hours.

• Fits side rails 12"–24" and tailgates 4'–6'
• Includes wire rope, hardware, and illustrated instructions
• Drilling and basic hand tools required for mounting

How much weight does the lift assist handle and what are the materials?

The system is rated for a 300 lb load capacity and is built from sturdy steel with a protective powder-coat finish to resist corrosion and wear. Components are sized for outdoor use and trailer conditions, while the cable and fittings are selected for durability under repeated cycles. This balance of strength and finish helps the assembly stay serviceable in road and weather exposure.

• 300 lb rated assistance capacity
• Powder-coated steel components for weather resistance
• Heavy-duty wire rope and mounting hardware included

How will this change day-to-day trailer use?

Once installed, the gate becomes significantly easier to open and close by hand — it feels almost weightless, reducing strain and speeding tasks like loading equipment or securing cargo. The smoother motion also lowers the chance of sudden drops or slams, improving safety when working alone. Maintenance needs for the gate and hinges are typically reduced due to the more balanced movement.

• Simpler, smoother manual lifting and lowering
• Reduced risk of gate slamming or sudden drops
• Less frequent hinge and alignment maintenance

Who is this for: This JY PERFORMANCE lift assist is aimed at utility trailer owners, landscapers, contractors, and weekend DIYers who want a safer, longer-lasting tailgate operation. It’s ideal if you use a 4'–6' open tailgate or ramp and want to reduce physical strain, protect trailer components, and speed loading tasks without replacing existing hinges or buying a powered lift system.
