![]() I prefer the circular cup style for axles. I also personally have a preference for relatively wide-flat topped jack stands such as in the US jack style or Sunex pin style or Hein Werner pin style for truck frames. Nevertheless, I have a suspicion that for your Ram 3500 you might run into problems with how HIGH 3 ton jacks stand can reach. but then again that might be old info in my memory because they change the standards every now and then. If someone remembers better, please correct me, but somewhere in my fuzzy memory I think ASME PASE requires jacks stands to be able to go over 2 times rating and ANSI requires jacks stands to be 1.5 times over rating. Regarding jack stands, as you see in the other posted videos, jack stands safety factors are much higher than the ratings. If you have a full sized jack (not the tiny trolley jacks), the overload bypass valve should open before you get anywhere close to causing the frame of the jack to collapse (Barring any stupid human behaviors that occur when operating jacks). if the load you are lifting is higher than the jack capacity, that valve will open and the transferred oil will simply get pulled out of the reservoir and pumped back into the reservoir with no lift of the jack saddle. Regarding hydraulic jacks, the capacity listed on the jack is what the overload bypass valve is set at. Sometimes the jack gets in the way and slows me down a bit, but makes me feel a little better with 6,000 pounds of steel over top of me. No weight is on the jack but it is extended to just within a 1/2 to 1/4 inch of a jack point to keep the vehicle at that height in case one of the stands fails. That being said, when ever I'm under a vehicle on stands, I always put my 3 ton service jack on the side I'm working on, just as a little bit of extra safety. ![]() The brand X have held up well, same with the Hein-Werner. Hein-Werner are US Made with foreign components, and brand X I think are from mainland China. I own a pair of 3 ton Hein-Werner and a set of brand X I picked up at a local non-chain auto parts store. Safety counter-weighted pawl ensures ratchet bar is engaged in position Heavy duty stamped steel construction provides stability and rigidity Sold and to be. I've been pleased with the quality of the set I ordered from them. You can order a set of the 6 ton's direct from US Jack. I like the six tons for my 'Runner and Silvy because they are taller than a 3 ton. There are far too many injuries and deaths each year due to jack failure without the safety of a jack stand. If a hydraulic seal or mechanical linkage were to fail under load, your car or truck could come crashing down upon you. I have a set of 6 ton stands that I use for my Toyota 4Runner and 1/2 ton Silverado. As a safety note a car or floor jack should never be used as a jack stand. I mainly just work on my stuff and close family, oil changes brake jobs, other easy stuff. I have 2 sets of three ton stands for the cars that I work on.
