Four of these easily support all four corners of my 6,000 lb., 2002 HD 4X4 Chevy Silverado - rock solid with no sway. And, just because I'm overly cautious, I also place a Powerbuilt 3 ton All-in-One hydraulic jack and jackstand unit at both front and rear as a back up.Pros: Very heavy with quality welds. Well designed. One unexpected plus that's not mentioned in the description - the adjustable slide bar support is solid steel, not hollow core. Very reassuring.Cons: None
