Automotive two post lifts are the single most common request we get from restoration shop owners around Ames, and almost every one of those calls turns into a conversation about the slab before it ever gets to a model number. We had a shop owner north of town call us the same week he closed on an old machine shed he was converting into a proper restoration bay. He wanted a two post lift installed by the following month. The problem wasn’t the lift he picked — it was that nobody had ever told him his floor needed to be a certain thickness with rebar tied in before that lift could go anywhere near it. That’s where this decision tree starts: not with the brand, but with the concrete underneath your boots.

Start With the Slab, Not the Lift
Every decision tree for automotive two post lifts should begin with the same question: what’s under the concrete right now? A lot of older shop buildings around Ames were poured for parking, not for a 9,000 to 10,000 lb two post lift with a vehicle hanging off it. Industry guidance generally calls for a minimum of 4 inches of properly cured concrete rated around 3,000 PSI, with rebar reinforcement, directly under each anchor point. If your slab is a thin patch job over an old dirt-floor garage, that’s not automatically a dealbreaker, but it changes the budget conversation immediately.
We’ve walked into restoration shops where the owner assumed a lift was a lift and the concrete was concrete. Then we get the core sample or pull old blueprints and find 2.5 inches of unreinforced slab from the 1970s. In that scenario the honest answer is either a new footing poured just for the lift posts, or stepping down to a lighter-duty two post configuration with a smaller footprint and lower anchor load. This is why we always ask about the building’s age and pour history before we ever talk model numbers — it’s the first branch in the decision tree, and it drives everything downstream.
Budget Tier One: Entry-Level Daily Driver Shops
If you’re running a small restoration operation and mostly need automotive two post lifts for general daily maintenance — oil changes, brake work, suspension jobs on the project cars between bodywork stages — an entry asymmetric two post in the 9,000 to 10,000 lb class covers most of what rolls through the door. These units ask less of your slab because the anchor pattern and load path are more forgiving, and they’re the most common configuration we quote for shops your size.
We quoted almost this exact setup for a shop in the Des Moines area recently: a 9,000 lb asymmetric two post, floor-plate mounted, no forklift on site for delivery. That’s a normal situation for a smaller building, and it’s a good example of budget tier one — the lift is affordable, the concrete demands are manageable, and daily maintenance work gets done without drama. If your slab passes a basic thickness check, this tier is usually where the decision tree points a general-purpose restoration shop.
Budget Tier Two: Heavier Project Cars and Trucks
Once your project list includes full-size trucks, vintage American iron with a lot of unsupported weight, or you’re doing frame-off work as part of daily maintenance rather than occasional builds, you move up to a 12,000 to 15,000 lb two post class. These lifts have wider footprints and heavier anchor loads, which means the concrete conversation gets more serious. We’re now firmly in territory where 4 inches of reinforced slab is the floor, not the ceiling, and we’ll usually recommend a soil-conditions check if the building is older or was added onto in phases.
This tier is also where rebar spacing starts to matter in a real way. Anchors for a heavier two post lift can land close to slab edges or seams, and if the rebar grid wasn’t planned with equipment loads in mind, you can end up with an anchor bolt that’s technically installed but sitting inches from a control joint with nothing solid behind it. We’ve corrected that setup more than once by shifting the lift footprint a foot or two to land the posts over better-supported concrete instead of pouring new footings.
Budget Tier Three: Commercial-Grade and Asymmetric Heavy Duty
Some restoration shops eventually take on fleet work, dually trucks, or larger project vehicles, and that pushes them toward the 15,000 lb-plus class of automotive two post lifts, sometimes asymmetric configurations designed to clear doors on longer wheelbases. At this level we’re not guessing about the slab — we want documentation, or we’re pouring new concrete to spec before the lift goes in. There’s no shortcut here, because the anchor pull-out ratings on heavier lifts assume a specific concrete strength and thickness, and skipping that step is how you end up with a lift that creeps or an anchor that pulls loose under load.
We’ve handled installs where a shop had already ordered a heavy two post lift before checking the floor, and the honest move was to hold the equipment in the warehouse for a few weeks while a new pad went in. It’s not the answer anyone wants to hear after they’ve already spent the money, but it’s cheaper than an anchor failure. If you’re in this tier, plan the concrete work into your timeline before you place the order, not after it arrives on the truck.
Reading Your Existing Slab Before You Order
If you’re not sure which tier fits your building, the practical move is a simple inspection before you commit to any specific automotive two post lifts. We look at slab age, visible cracking, whether there’s a control joint running through the intended footprint, and if possible a core sample or the original pour records. A building that was poured as a commercial garage bay in the last few decades is usually in decent shape for a mid-weight lift. A converted pole barn, old dairy building, or anything poured before rebar reinforcement was standard practice needs a closer look.
We’d rather tell a shop owner in Ames that they need a new footing before we take an order than sell a lift that sits on a slab that can’t hold it. That conversation up front saves everyone a bad outcome six months later — a leaning post, a cracked slab, or worse.
Matching Configuration to Daily Maintenance Workflow
Configuration is the next branch in the tree, and it’s less about the concrete and more about how you actually use the bay day to day. Symmetric two post lifts center the vehicle between the posts and work well for general daily maintenance where you’re in and out of the cab a lot. Asymmetric designs shift the posts to open up door swing and driver access, which matters if your daily work involves a lot of climbing in and out for test drives between repairs. For a restoration shop doing constant daily maintenance on a rotating lineup of project vehicles, we usually steer toward asymmetric unless the building’s column spacing forces a symmetric footprint.
What Freight, Delivery, and Install Actually Look Like
Once the slab and configuration are settled, the last branch is logistics — and this is where a lot of shops get surprised. We need to know if there’s a forklift on site, whether the building has a pit or is a straight floor-plate install, and what the loading dock or door situation looks like for a lift that arrives on a flatbed in a few large crates. Smaller two post lifts can sometimes be handled without a forklift on site; heavier commercial units generally can’t. We ask these questions on every quote because getting it wrong on install day costs everyone time.
Lead time is the other piece. Depending on the manufacturer and configuration, automotive two post lifts can take anywhere from a couple weeks to a couple months to arrive, so if your concrete work still needs to happen, we build that into the schedule rather than letting it become a last-minute scramble.
