They came yesterday. The boxes were perforated, cut and torn, and retaped in numerous places. And were made from that cheap, Chinese corrugated cardboard that you can easily tear apart with your bare hands. But the ramps themselves were fine, considering they started their journey somewhere in China. (God knows where).
The only problem was the safety locking pins they included, that go through the telescoping box metal on the jacking plate were missing on one of them. That turned out to be somewhat of a blessing in disguise. Because as it turns out, they drilled the holes through the box metal large enough to easily accept 3/8" dia. pins, but they included 5/16 dia. Why I have no idea. So I went down to Ace Hardware and picked up 4, 3/8" dia. Clevis pins 3" long, and I was good to go.
Overall they look well made. All the welds are heavily fused, and the units appear to be good and solid. And they're light enough so they're not difficult to move around. The jacking plates come right off once you remove the pins, which makes them even lighter to get into position. The hydraulic jacks mounted in the units are rated for 5 tons each, work smoothly, and are easy to raise and lower.
With the jacks all the way down, (the position they're in when you drive the vehicle up on them), they raise the bottom of the front tire 9-1/2" high off the ground. With the jacks pumped up high enough to get the locking pins into the holes at the highest position, they raise the bottom of the front tire to 14-1/2". I doubt I'll even have to use the jacks on either my Jeep or my truck.
With my Toyota that's another story. Because of all that dam low plastic fascia they have wrapped all around the front end, I can't just drive it up on to these ramps. They won't clear. So I'm going to have to place a couple of 2 X 6's in front of the ramps, and drive it on from there. Then it should be fine. I was more or less expecting this, but what a PITA. That car sits so low I really think I'd have the same problem with ANY ramp. And even if I found a set, I doubt it would get the car high enough to get under it without incorporating some type of jack.
I'll try to post some pictures of them later on. But so far I like what I see. I'm going to pick up a couple of rolls of that rubberized tool box drawer liner to set them on, so they'll have less tendency to slide along the floor when I drive up on them.
