A Pre-Purchase Checklist for Automotive Two Post Lifts (and What They’re Worth Later)

A guy in northwest Iowa emailed us about automotive two post lifts after spending a winter doing oil changes on ramps in an unheated shed. He’d finished a 30×40 pole building, had 12-foot sidewalls and a fresh slab, and wanted something he could use for brakes, fluids, and the occasional bigger job on his own vehicles. His real question wasn’t which model — it was whether he’d get his money back if he ever sold it. That’s a smarter question than most first-time buyers ask, and it changes what you should shop for. This article is the pre-purchase checklist we walk hobbyists through, with an honest section at the end on trade-in and resale values.

Checklist Item One: Measure the Building Before You Shop

Every bad lift purchase we get called about starts the same way — somebody bought first and measured second. Take a tape measure and write down four numbers: clear ceiling height to the lowest obstruction, overhead door height when fully open, slab thickness, and the usable width between whatever is on either side of your intended bay. Then add a fifth: the distance from the bay to your electrical panel.

The northwest Iowa buyer had 12-foot sidewalls, which sounds generous until you account for the truss chord, the garage door track in the raised position, and a couple of shop lights hanging down. His real clear height was closer to 11 feet 6 inches at the lowest point, which is workable for many overhead models but tight for raising a tall pickup to full lift. Width matters too — a two-post needs roughly 12 feet of column-to-column footprint plus room to open doors on both sides once a vehicle is up. If you’re working in a 24-foot-wide building with a workbench along one wall, do the arithmetic before you order. We’ve had to tell more than one person that the unit they already paid for isn’t going to fit, and that’s a conversation nobody enjoys having.

Checklist Item Two: Verify the Slab and the Anchors

Concrete is the number one reason a home-shop install gets delayed. Manufacturers of automotive two post lifts typically specify at least four inches of 3,000 PSI cured concrete, and some heavier models want six. A brand-new pole building slab is often four inches at the edges and thicker in the middle, or the reverse, depending on who poured it. Guessing is not a plan.

The cheap fix is a core sample or a small test drill in the exact spots your columns will sit. If it comes back thin, you pour two footing pads — usually four feet square and deeper than the surrounding slab, tied in with rebar and given a full cure before anchors go down. That adds a week or two but it’s dramatically cheaper than the alternative. The other thing to check in Iowa buildings specifically: in-floor radiant heat. It’s increasingly common in new shops, and drilling a 5/8-inch anchor hole into a PEX loop ruins your day and your floor. Get the tubing layout from your builder or have the floor scanned. If heat lines make anchoring impossible in your preferred spot, that’s a legitimate reason to consider a four-post or a mobile column setup instead — see our two-post versus four-post comparison for how that tradeoff plays out.

Checklist Item Three: Capacity Sized to Reality, Not Ego

For general daily maintenance on passenger cars and light trucks, 9,000 to 10,000 pounds covers essentially everything a hobbyist owns. One buyer told us his heaviest vehicle was 6,000 pounds and he was looking at a 9,000 lb class unit — that’s a sensible margin. Another described wanting to lift a passenger vehicle around 7,000 pounds maximum. Neither of them needed 15,000 pounds of capacity, and buying it would have cost more, weighed more, and demanded more ceiling.

That said, don’t cut it thin either. Capacity ratings assume balanced loading across all four arms, and a lopsided load — say, an engine still in but the transmission out — concentrates weight unevenly. We generally suggest picking a capacity at least 30 percent above your heaviest realistic vehicle. If you own a half-ton pickup at 5,400 pounds and think you might buy a three-quarter-ton someday, 10,000 pounds is your number. If a diesel dually is anywhere in your future, step up. The cost difference between 10,000 and 12,000 lb models in the same product family is usually modest, and it’s one of the few places where buying a little more than you need pays off both in daily confidence and later resale.

Checklist Item Four: Power, Plumbing, and Install Logistics

Most home-shop automotive two post lifts run a 220V single-phase motor drawing around 20 to 30 amps. That means a dedicated circuit and a disconnect near the power unit. If your pole building has a 100-amp subpanel with a welder and a compressor already on it, get an electrician to look at the load before delivery day. We show up to a fair number of installs where the lift is bolted down and ready and there’s no power to it.

Then there’s the physical logistics. Columns on a 10,000 lb unit weigh several hundred pounds each and arrive on a freight truck, often with no liftgate unless you paid for one. You need a forklift, a skid steer with forks, or three strong friends and a plan. One buyer we worked with had his own forklift, which made the drop simple. Another had nothing, so we scheduled our truck and crew for the same window. Decide early whether you’re doing a self-install or hiring it out. Self-install is genuinely doable for a mechanically inclined person over a weekend — level the columns, drill and set anchors to torque spec, route cables, bleed the hydraulics — but a professional install comes with a shimming job done right and a warranty relationship that means something later.

Checklist Item Five: Parts Availability Five Years Out

This is the item nobody thinks about and everybody eventually calls us about. A two-post lift is a simple machine, but it has consumables: equalizer cables, hydraulic hoses, cylinder seals, arm restraint gears, lock springs, and lift pads. Every one of those will need replacing eventually on a lift you keep for fifteen years.

The question to ask before you buy is: who stocks parts for this brand in five years? For Rotary and Challenger, the answer is easy — those parts pipelines are deep and we keep common items on the shelf in Ames. For imported units from brands that rebadge whatever factory quoted lowest that quarter, the answer is sometimes nobody. We’ve had customers send photos of a failed carriage lock on a lift with no manufacturer nameplate and no serial pattern anyone recognizes, and at that point you’re fabricating or scrapping. Before you buy, search the brand’s parts catalog and see if it exists as a real document with real part numbers. Call a distributor and ask if they stock cables for that model. If nobody can answer, that tells you something. Our parts lookup covers most major brands, and our cable replacement guide walks through the most common wear item.

What Automotive Two Post Lifts Are Actually Worth Used

Now the resale question. A well-maintained, ALI-certified two-post from a recognized commercial brand typically holds somewhere in the neighborhood of half to two-thirds of its original purchase price on the used market after five to eight years, assuming light home use and no damage. That’s a strong retention curve compared to most shop equipment. Uncertified imports with no brand recognition often bring a quarter of what was paid, sometimes less, because buyers correctly worry about parts and liability.

Three things drive used value more than anything else. First, the ALI Gold label — certified units sell faster and higher, full stop. Second, documentation: keep the manual, the original invoice, and any inspection records. A folder of paperwork routinely adds meaningful money to the sale. Third, condition of the wear items. A buyer inspecting your lift will look at the cables first, then the arm restraints, then the anchor bolts. Fresh cables and clean paint on the columns signal a lift that was cared for. We also see people ask about trade-in. We do take equipment in trade against a new purchase in some cases, and we’re straightforward about it — the value depends on brand, age, and whether we can resell it with a clear conscience. The practical takeaway: buying a known brand slightly above your minimum need is usually the cheapest path once you account for what the equipment returns later.

Putting the Checklist Together

Run the five items in order — building measurements, slab verification, capacity sizing, power and logistics, parts availability — and the model choice mostly makes itself. For the northwest Iowa buyer, the checklist landed on a 10,000 lb asymmetric clearfloor unit from a brand we stock, installed on a slab we test-drilled first, on a dedicated 220V circuit he ran while the building was still open. He does his own oil changes, brakes, and fluid work now, and he knows the lift is worth real money if his situation changes.

If you’re weighing automotive two post lifts for a home shop in Iowa, Nebraska, Minnesota, or anywhere in our service area, call us before you order. We’ll ask about your building, your vehicles, and how long you plan to keep the equipment, and we’ll tell you plainly whether the unit you’re eyeing is a good buy or a future headache. Sometimes we talk people out of a two-post entirely and toward a four-post because they mostly want storage and rolling-jack access. That’s fine — the goal is that you end up with the right machine, not that we move a specific SKU. And if you already own one and just need cables, pads, or a cylinder, we can help with that too.
