For anybody who is skeptical about buying these lift ramps, don't be. I drove my truck on the ramps with no problem and I had it on the ramps for hours with no issue. I was underneath my truck the whole time it was on the ramps. Best thing since sliced bread. My truck weighs 5500 lbs.
These are solidly built ramps that come in a single box big enough to make our Fed Ex driver cry. Very easy to assemble (four bolts, four pins, and done). Could benefit from a welded pipe to hold the bottle jack lever when not in use but I solved this lack with zip ties and scrap ABS pipe. Lifts even our heaviest truck without issues.
They're strong and lift cars perfectly. I actually used two of these under the fronts of the car's frame rails to lift it high enough to have the wheels off it and be able to work under it (handy when you're pulling the engine, dropping the subframe, etc.). The ramps have safety pins, Once you raise them to the desired height, you can stick the pins through them to lock them so that even if the rams fail, they won't drop.
Ramps came assembled and ready to use, both seem to work properly. Very sturdy and not flimsy at all. Much better quality than i thought.
This works really good for low ground clearance cars and just to be safe use heavy duty jack stands along with the ramps I changed the fuel pump on a 06 chevy malibu had to drop the gas tank and these raise the car up off the ground really good.
