On the bottom it tells you not to exceed 3,000 lbs, 6,000 for the pair. What does the page say? Amazon sells 2 plastic ramps that look identical and cost the same but one claims to hold 16,000 and the other is different. I bought the "different" because it's Amazon's choice (because there's more profit in selling a poorer one for the same as a good one). Even if they said they hold 16,000 lbs, they'd be lying because those hold 4,000 each. Let's stick with these 3,000 lb ramps. My wagon has a 4 liter engine and it's the same car as the ones with a 2 liter engine. The weight of the front is vastly greater than the rear. I think it's 65/35. In any case, these 2 ramps are never holding BOTH THE FRONT AND THE REAR of any car. You'd need at least 2 more ramps. The ground clearance will never let you get a ramp under the car for the rear to drive up them and in fact they say not to do this. This means that they lied to me and they are lying to you. What's worse, my number hits the ramp. Some of these have ramp extenders. Not on Amazon yet. zbut these extenders are $200. The lack of economies of scale drives up the price. Bottom line, the ramps together hold 6,000. Do not assume the front weighs the same as the rear. They said they hold 12,000 lbs. That is a lie. Your tires must be no wider than 9.5" I gotta say this. I get so tired of asking the most basic and obvious questions about the products for sale on Amazon. What the hell is the deal? I had to ask 4 questions on a recent purchase. it is a cylinder in shape. "How long is this? What is the diameter? How does it stay in place? Does it come with adaptors to fit cars with different sized holes for these? How many peak watts and how many watts rms do they handle? Is the crossover built into the speaker? I don't see one. I also see mention of a 3 db attenuation. That's would reduce the high frequencies and yet the literature clearly states that the 3db button makes the sound crisper and cleaner with "more highs and clarity"? Which is correct? What is the impedance? Why are none of these necessary pieces of info not shown on the page? Is that just to waste our time and infuriate us? If so, you're doing a fantastic job. Would you consider getting a different job because we're all VERY tired of asking for every GD scrap of necessary information? Obviously the last 3 were made up, because Amazon doesn't give us enough room to ask a question specifically enough for the reader to know what we're asking about in technical things, but it's obvious they're fake for other reasons too. However, the rest are real, I swear. I asked a number of absolutely necessary questions on an amified because absolutely nothing was posted. Eventually, I asked why none of my questions were being posted or answered. So I bought it just so I could read the manual. I did, it was crap, I sent it back and they wrote me an email, completely stunned that I wasn't satisfied. I told them precisely what was wrong with the product and with the most generous time they could muster they offered to assist me with the purchase of an even more overpriced piece of ... whatever. I already told then that for half the price I already bought one that outranks them in every category. Maybe that's why these companies don't waste their time posting information? Then there's these ramps. There are 2 that look identical. But 1 is 12,000 lbs (that's 6,000 lbs for 2 ramps in the add, lying jerks). Then there's another that's 16,000 lbs (that's 8,000 lbs for 2 ramps they are selling lying jerks.) Both are the same orice. Both are Amazon's recommendation. Why recommend a weaker ramp for the same price? Why even show us a ramp that is the same in all respects but weaker?. Who wants a weaker ramp? Not me, but I got confused by the number of ramps. I don't even know if my car bumper can clear the incline. The steel ones didn't. I don't drive a race car. It's just a VW wagon. (Anyone want to buy some steel ones. They're free. just come get them) The summary of my review is that they te you to put it on a level surface but if you look on the bottom, they leave large moulding blobs that would not be good for the ramp. Not a problem. The weight capacity is a big problem because this is a lie. You couldn't get 12,000 lbs on the ramp, God for only 6,000 lbs evenly distributed on thev2 they're selling on the page. You'd need 2 more ramps and a mini car with huge ground clearance to get a ramp under the car. Never gonna happen. It's a lie. 2 ramps is what they're selling, those are what you'll use, mostly on the front where the weight of your car is as much as 3 times heavier (75/25 split like some trucks). Complain to Amazon about listings with little or no information, false information. No modern pick-ups should buy these. Widest tire size at it's widest should not exceed 9.5". Do they make trucks this little? I don't know if my bumper clears the ramp. I have no spoilers. It's just that the steel ones have short ramps up to 6.5". These are a little longer.
