Replacement left and right springs designed for Mega Ramps and similar trailer ramp hinge assemblies that use a 1.50 inch diameter rod or shaft. These springs provide lift-assist tension to help raise, lower, and securely support heavy ramp gates on equipment, implement, and utility trailers. :contentReference[oaicite:0]{index=0}
Ramp assist springs are critical in reducing user effort when lowering or raising heavy trailer ramps. Without adequate spring tension, ramps can fall freely or be difficult to lift back into the locked position. :contentReference[oaicite:1]{index=1}
The left and right springs in this kit hook into the double-hinge assembly on your ramp and provide opposing tension to balance movement. Always match spring diameter and length to your existing shaft to ensure correct fit and safe operation.
