Better Than My Original System

My original ramp spring was underpowered from the factory. This kit with the 160lb spring makes a huge difference. Now I don’t have to strain my back every time I load my ATV. Highly recommend for any heavy ramp door.

Perfect for My Enclosed Trailer

My 8-foot trailer ramp was a beast to lift. This kit provided the perfect solution. The spring and cables are clearly high quality. Everything fit together nicely, and it’s a relief to not have to grunt every time I open the trailer.

Solid and Reliable Upgrade

My old spring was starting to weaken, and I decided to replace the entire system with this kit. The new cables and drums are a huge improvement. The ramp lifts smoothly and feels much more secure.

High-Quality Components

You can tell this kit is built to last. The spring feels very heavy-duty, and the cables are much thicker than my old ones. The bearing brackets are solid steel, not flimsy stamped metal. Great kit overall.

All Parts Included, Great Value

I shopped around for a bit and this kit was the most comprehensive for the price. Having all the hardware and cables in one box saved me from running to the hardware store multiple times. The quality is top-notch.
