I'm in the midst of my first real fab job on my new 4 post drive on lift and I had to share this picture.
What you see there is Barney on the lift ramps with one bridge jack holding the frame up right behind the rear tires and another bridge jack under the front suspension compressing it to full compression (springs out).
I'm installing a new weld in front sway bar and needed to have the frame at ride height and be able to completely flex the front suspension to check for bind. The 4 post lift and bridge jacks made this pretty easy to do. It would not be nearly as easy on a 2 post lift.
Overall I like the lift so far. I've had to learn to work around a few things that are difficult but nothing is impossible yet. The ramps getting in the way is about a push with using them as a workbench, no biggie either way. The jacks don't have enough throw in them so it's always a battle about lifting, blocking the car up with something then lifting again after resetting the jacks...probably made worse by my car being so low to start with. The overall lift function is awesome, no bind anywhere and very sturdy. One of the bridge jack does leak which is frustrating and it will pop my 20 amp 120v breaker every now and again.
Anyway, so far so good...
