VIVBOO Trailer Tailgate Lift Assist for 12-24" Rails, 4-6 ft Panels — Dual-Spring Bolt-On

VIVBOO Trailer Tailgate Lift Assist is a bolt-on, dual-side spring system that halves the effort needed to open and close open-utility tailgates and ramps sized for 12–24" rails and 4–6 ft panels.

This heavy-duty lift assist converts strenuous tailgate and ramp handling into a simple slide motion, ideal for frequent hauling, farm work and backyard projects. Made from reinforced steel with a galvanized base and painted finish, the unit resists rust and spreads force evenly across both sides to reduce wear. The kit ships with all mounting hardware, gloves and clear instructions so most users can install it quickly without welding or custom fabrication.

How does the dual-side lift reduce the effort of raising a heavy ramp?

The VIVBOO system uses two matched springs inside an enclosed housing so both sides of the tailgate share the load. When you lift, the springs counterbalance the ramp’s weight, making the motion smooth and controlled rather than sudden or jerky.

• Dual-spring design spreads force evenly to both hinge points.
• Enclosed construction avoids pinch points and keeps springs protected.
• Reduces manual pulling force significantly for safer operation.
• Balanced action minimizes wear on hinges and tailgate edges.

Will this unit fit my trailer’s rails and ramp sizes?

The assist is built for open-utility trailers with vertical side rails between 12 and 24 inches tall and ramp or tailgate panels 4 to 6 feet in height. Its universal bolt-on layout accommodates most common rail placements without cutting or welding.

• Compatible with 12–24" rail heights and 4–6 ft ramp panels.
• Bolt-on mounting works with standard trailer hardware locations.
• Included fasteners and braces fit typical steel frame profiles.
• Clear instructions reduce the need for special tools or fabrication.

How durable is the VIVBOO Tailgate Lift Assist outdoors?

Durability was prioritized with a galvanized base plus a painted outer layer to protect against moisture, mud and corrosive conditions. The reinforced steel frame and enclosed mechanism keep components aligned and shielded for long-term outdoor service.

• Galvanized base prevents rust at contact points.
• Outer painted finish adds an extra corrosion barrier.
• Thick steel frame supports repeated heavy use.
• Enclosed mechanism reduces exposure to grit and water.

What is the load capacity and how is it measured?

When both sides are installed and the forces are balanced, the VIVBOO lift assist supports a combined, uniform operating load up to 300 pounds. This rating applies to balanced dual-side configurations; single-sided or asymmetric setups will alter effective support.

• Rated for a balanced dual-side load of up to 300 lbs.
• Rating assumes correct installation on both sides of the tailgate.
• Uneven or single-side use reduces the supported weight capacity.
• Recommended for common utility loads, bikes, mowers and small equipment.

Who is this for: VIVBOO’s Trailer Tailgate Lift Assist is built for trailer owners, landscapers and homeowners who handle ramps frequently and want a safer, easier way to open and close heavy tailgates. It fits utility trailers and common open-bed haulers with 12–24" side rails and 4–6 ft ramps, and it’s best for users who prefer a bolt-on upgrade that resists rust and reduces hinge wear without custom fabrication.
