suspension install question

[95LT1Z28]

Guys im going to be putting on a adj phb, non adj lcas with relocation brackets, an adj tq arm, and new shocks. I have a pit in the garage at my house so my question is, can i do one of these mods at a time and not have to lift the car off the ground?

You might be able to have access to everything. If you do, it shouldn't be a problem as the suspension will definitely be properly loaded sitting on all fours.

i had mine up in the air when i did my suspension. Just the rears were off the ground
