6" min. Also kind of depends on the mix density but 6" is typically the minimum working order. Also the lift footprint makes a difference as a two post will put more stress on the slab than a four post. The slab in my new shop is 10" thick on a 12" tamped stone base. It’s wired at half depth with 4x4"x.25" wire mesh and I’m not putting a lift in. I just absolutely did not want cracking. I want to say it’s 10Klb mix. It’s relieved in 8x8 foot blocks(cuts to promote cracking along the cut vs through the slab if it does actually split.

I really wouldn’t put a lift on a 4" slab. Just my opinion.

I’m not planning on 4" under the lift, but the other half of the garage is just going to be regular parking space for my camaro. My though was to pour the one side thicker instead of the whole thing 6 or 8 inch to save so $$ on concrete. That shit is expensive up here.
