Pangda 4 Pack Solid Rubber Auto Lift Pads 6-3/8" x 4-3/4" x 3.15" Anti-Skid Lift Block Spacer Pad for Automobile Car Lifts, Jacks and Racks, 4000 Lbs Capacity

Decent Quality. Good Price

These blocks weigh a lot. They're really heavy duty. They work really well, but I think I should've got the 2" instead of the 4". They're pretty tall for a car, probably perfect for an SUV or truck

These are high-quality. They are extremely solid and thick. The fit is as described, as well as the slip resistance. They function as intended without any problem. It is a good way to protect the vehicle and the person under it.

When the box these came in arrived, I had no idea what they were. At first, I thought it was a lead acid battery that I had ordered, but it didn’t have the warning stickers about hazardous materials. Inside, were the densest, chewiest, most horrible tasting brownies that I have ever encountered. Actually, they were the PANGA Auto Lift Pads. Something most people don’t think about what happens when raising up a vehicle with a metal jack in contact with a piece of metal on a vehicle. As the vehicle rises, the angle of contact changes. What may have started as two 3 inch sections of metal solidly against each other can end up with a blade thin contact as the angle between the jack and the car changes. This invites the jack or the vehicle to travel off at an angle from the jack point. I really worried about this while I was crawling under a 1-ton truck suspended in the air. I have some pieces of semi-truck tires that I use as padding, but you could only jack the truck up a few inches before putting stands under the chassis and repositioning the jack to keep a favorable angle. Something that I do differently than most is that I employ house jacks as jack stands. On the 1-ton, the chassis is already 18 inches from the ground before I begin to jack it up. Using these blocks on the stands help keep them in contact with the frame. For the truck, I put blocks on three of the stands and one on the main jack. In total, I have about half a dozen stands plus three floor jacks underneath the beast. Even with all these precautions, I still keep an eye on everything. These also fit well on the arms of our asymmetrical lift. On some cars, the round posts don’t fit well and these can be positioned on each arm to pick up a car without marring the undercarriage. Honestly, I did not know something as nice and durable as these PANGA blocks existed, at least for a Joe Schmoe like me to buy. The seller spent a lot of time telling how safe this was for your car, how it could prevent damage to it. I can appreciate that but a big concern is number two, me. Of course, number one is the people that work with me. $100 to make lifting vehicles safer for people is money well spent.
