I use the 3-ton low-profile HF jack on my 2016 Platinum (20" wheels, stock suspension). While testing everything out for upcoming tire rotation, I found that the jack worked just fine (raises to 19 3/4"), but putting my Tundra on the HF 3-ton jack stands at the required jacking/support locations, even on their max height, resulted in the wheels touching the ground. Back to HF to get their 6-ton jack stands that have several more inches of height and I also picked up the Steel Floor Jack Cross Beam (Floor Jack Cross Beam
). The cross beam attachment lets me adjust the pads to evenly jack-up the front end on solid points at the ends of the front cross member. I jack up the front end, slide the 6-ton stands (raised to three teeth showing) under the front frame support points, and lower the front onto the stands. Getting the original bolt loose from the saddle (10mm hex key and either a breaker bar or rubber mallet while bracing jack against garage wall) took a bit of doing, but it's now easy to switch between the two attachments.
The floor jack cross beam doesn't work for the rear, so I do a quick switch-out to the normal jack saddle, and raise the rear end under the pumpkin and slide the stands beneath the rear support points. For my truck, everything is level within a hair of perfect on the 6-ton stands with the front stands raised to three teeth showing and the rear stands at their lowest setting with no teeth showing. Wheels are off the ground and ready for impact wrench. I also added the rubber pads for jack stands (Rubber Pads for Jack Stands
) to my 6-ton stands. Some pretty heavy whacks with a rubber mallet are needed to get those on, and they're on for good.
In case it helps anyone else, I found this universal saddle pad that fits the detents of the HF jack saddle: Jack Pad Universal
. We don't need the frame rail cutouts for the Tundra, but the pad is better than putting a shop rag on the saddle.
The floor jack cross beam is rated for 2 tons and as others have noted, we're not picking up the entire weight of the truck at once. The instructions in the box list the 3-ton jacks as compatible with the cross beam, though the floor display model in HF, attached to a 3-ton jack, had a warning on it saying something to the effect of "for use on up to 2-ton jacks".
