Rear axle drop when car lifted.
 

Is there any way to prevent the rear axle from sagging all the way down to the end of the shock travel when jacking up the car? I have a Ride Tech 4-link and coil overs in my 69 firebird project that is always going up and down on my 2-post lift. When the car goes up, the rear goes down until the shocks are extended all the way out and the springs unload.

are you trying to do something or prevent something?

what are your current spring specs? length weights

Not sure what my spring rates are, but the coil overs are what came with my stage 2 kit from Ride Tech for a 1st gen F-body. The shocks are single adjustable. I am trying to prevent the shocks from being completely unloaded when I lift/jack up the car. When this happens, the weight of the rear end is held by the unloaded shocks. Also, since the springs are completely unloaded as well, I have to be careful that they pop back into place as I place weight back onto the suspension. Since I am still in mock up/assembly stage, I placed the rear at ride-height and then used a rope on each side to secure the rear axle to the old rear snubber bolt hole and tied tightly. This prevents the axle from being able to drop. The straps mentioned earlier might be the answer.

Replace shocks with these until you are not in the mock up phase.

FWIW, you are not hurting anything with what you are doing right now.

I don't think your springs should be falling out of place at full drop. Add keeper springs that are made to prevent this.

I recently added the zero-pound springs to my rears. Over time, the spring started rubbing through the shock body on my Ridetech shock bodies when they unloaded, to the point that I sent them back to RT and had them rebodied. These are simple to install, although not exactly a cheap solution, and they allow full droop on my setup without unloading the spring.

It ends up being about $160 for a set for the 2 rears...

Here they are installed and assembled:
