I bought a Harbor Freight Daytona low profile long reach jack several years ago for my lowered Magnum R/T. It was low enough to get under it and lift it higher than the regular jack I had. It also works great on my Trail Boss. The only thing I don't like is only on this model the bolt for the handle is on the front side of the jack and if trying to pull the jack with anything on it or on rough surfaces, the handle will pop out. You can't put a longer bolt in because it needs to spin to allow for the handle to spin to open and close the hydraulic opening to lower or raise the jack.
I need some bigger jack stands. I borrowed some big 6 or 8 ton ones my dad had when working on my Avalanche and haven't returned them yet. I just have some 2 tons that are OK but not super tall.
I couldn't tell you the brand name of all of my jacks, some of them are older than me. I know one is a smaller craftsman almost 20 years old, one is a 3 ton purchased at NAPA within the past 10 years, and the others I have no clue of their origin. Hydraulic jacks RARELY go bad, and considering you are never under the vehicle while the jack is in use, the jack is really pretty irrelevant to me. My concern is primarily with the stands since the jack is used only to raise and lower (which you will never be under a vehicle while doing) while the stands support the weight long term while you are working beneath the vehicle.
Any ol' jack will do, its the stands/ramps you don't want to cheap out on.
Everybody has the "one off" in some category.
Regardless, a faulty/leaky jack generally wont injure you if you are using it only for its intended purpose. A faulty stand, when used for its intended purpose, can injure/kill you.
