Jack to lift the truck?

[NorskieRider]

Which jacks are you using to lift the truck and unload the suspension?

(I'd love to have the space for a 2-4 post lift but that's not in the cards for now)

I use 2 hydraulic roller jacks each rated at 3 tons. Make sure to support the trucks with jack stands before working under the vehicle and work on a level, clean surface such as uncracked concrete.

Oh great, now I have a new envy: Lift Envy. I'll put that right next to the Garage Envy ;-)

Is a 10" lift under the frame enough to get the tires off the ground? I'm thinking something like this:

I just use a standard 3 ton floor jack under the center of the rear end, Then place jack stands under the tubes of the axles. The problem with lifting the frame with the uniijack you posted is you have to lift the body and the suspension, Where when you go under the rear end itself it compresses the suspension and gets the tires off the ground much quicker. Not to mention tat you are going to have to pump that hydraulic jack 418 times to get to the full 21" of extension LOL.

i rock this combo no complaints but the jack is heavy something like 100 pounds

I'm assuming that jack lifts from 11 to 21 inches, i.e. it will only lift 10 inches.

Jacking under the diff is fine for getting the tires off the ground but if I want to unload the suspension I'll need to lift on the frame.

I have the 2-ton Daytona, low enough to get under my sports cars and tall enough to get the Outback wheels off the ground. But the RAM frame starts at a much higher point, so I'm thinking it may not be tall enough to use under the frame (and 2T may not be enough to lift under the diff either).

If your floor jack won’t go high enough just get some hydraulic floor jack extentions. Of course, make sure you are using jack stands after it’s lifted and don’t rely on, or trust, the jack to stay up.

I've used the Daytona jack under the pumpkin, and then jackstands right in front of the control arm brackets. I then removed the wheels and lowered the jack. Still had a few inches of ground clearance and the rear was completely extended. Haven't had to do the front, though.

You can easily unload suspension when jacking under the pumpkin. Lift it up high enough, throw jack stands on the frame and lower jack. Suspension will drop. If you jack it high enough, don't even need to remove wheels. Otherwise you can remove the wheels before lowering the jack to get you more extension of suspension.

Fwiw, I don't ever lift the rest of any vehicle, with a rear differential, from the frame. Always use the pumpkin. One jack, one time, both wheels off he ground. For the front, I lift from the center of front crossmember just in front of engine. once again, one jack, on time both wheels off the ground.

FWIW, I have one of the 3-ton low profile jacks from Harbor Freight, and some 6-ton, and 3-ton jack stands from Amazon
