Many trailers require excessive lifting effort to raise a tailgate ramp. This invention reduces this lifting effort. The invention consists of a right and a left unit. They are installed with fasteners on the lower rear corners of the trailer frame aligned with the existing tailgate ramp hinges. They can be easily installed with minimal labor and no special tools or skill. The main functional element of each device is a torsion spring with the moving spring arm linked to the trailer tailgate ramp. As the tailgate ramp is fully lowered to the ground, the amount of lift effort approaches zero with still sufficient weight to allow the tailgate ramp to remain fully opened. As the tailgate ramp is raised to close, there is very little lifting effort required. The device has a set of sizes and torsion spring values that enable tuning to the specific trailer application.
