If you’re a weekend mechanic near the Iowa-Missouri border thinking about putting an auto lift in your garage so you can finally do your own shocks and struts without fighting a floor jack and a stack of jack stands, the equipment itself is the easy part. The hard part is what happens before the truck with the lift ever shows up. We’ve installed lifts in pole barns, attached garages, and old dairy sheds all over southern Iowa, and the jobs that go sideways almost always trace back to something nobody checked before the order was placed. This is the pre-purchase checklist we walk hobbyist customers through so the install day is boring in the best possible way.

Why Suspension Work Changes What Auto Lift You Actually Need
Not every auto lift is built the same way for shock and suspension jobs. If you’re mostly changing oil and rotating tires, almost any two-post will do. But once your list includes struts, control arms, or sway bar links, you want unobstructed wheel access and enough clearance to hang the wheel and let the suspension droop fully. A lot of hobbyists come to us wanting the cheapest lift they can find, then discover the arms are in the way of the strut tower or the lift doesn’t have enough drop height for their truck’s suspension travel.
We usually steer suspension-focused customers toward a two-post asymmetric lift with adjustable arms, because it clears the rocker panels and doors and gives you room to swing a wrench without the arm pads fighting your control arm. Drive-on four-post lifts are great for alignments and storage, but they’re not ideal if you need the wheels hanging free. Tell us up front what you’re actually doing on the lift — shocks, struts, ball joints, full suspension rebuilds — and we’ll point you at the right auto lift instead of just the cheapest one.
Ceiling Height and Overhead Clearance
This is the single most common reason a lift order gets delayed after the fact. We ask every customer for their ceiling height, and we mean the actual clear height to the lowest obstruction — not just the rafters, but any garage door opener rail, light fixture, HVAC duct, or storage shelf hanging down. A two-post lift needs enough overhead room to raise a full-size truck or SUV to comfortable working height, which for suspension work usually means chest height or higher so you can see what you’re doing under the wheel well.
Along the Iowa-Missouri border we see a lot of older pole barns and detached garages built before anyone thought about lift clearance. Measure from the floor straight up to the lowest point, not the peak of the roof, and measure in more than one spot because older buildings settle unevenly. If you’re borderline, tell us the vehicle you’re working on most — a lifted truck needs more headroom than a sedan — and we can talk about shorter columns or different lift styles before you’ve already paid a deposit.
Concrete Floor Thickness and Condition
An auto lift puts a lot of point-load stress on your slab, concentrated right at the anchor bolts. We ask every customer about slab thickness, age, and whether there’s rebar or wire mesh in it, because a lift anchored into a thin, cracked, or unreinforced floor is a liability no matter how good the lift itself is. Most manufacturers want a minimum of four inches of solid, unpatched concrete, and full strength concrete cure — not just a poured floor from last month that hasn’t set up yet.
If your garage floor is original to a house built decades ago, or if you’ve got visible cracking, spalling, or a floor that’s been patched around old drain lines, say so before you order. We’d rather have that conversation on the phone than show up with the lift and find out the anchors won’t hold. In some cases we can still make it work with a different anchor pattern or a poured pad addition, but that’s a conversation for before you buy, not the morning of install.
Power Requirements: 110V or 220V
Every auto lift needs power, and getting the wrong assumption here is an easy, avoidable delay. Most home-garage two-post lifts run fine on a standard 110-volt circuit, but some larger commercial-grade units and certain four-post configurations need 220V single-phase. We’ve had hobbyist customers assume they needed a big electrical upgrade for a lift that actually only needed a dedicated 110 outlet, and we’ve had others assume 110 was fine when the motor spec called for 220.
Before you buy, check the motor spec sheet for the exact model you’re considering, not a similar model, because voltage requirements vary. If you’re not sure, send us the model number and we’ll tell you straight what it needs. If you do need 220, get an electrician scheduled before the lift arrives so you’re not paying for a return trip. And if you’re adding an air compressor for pneumatic unlock, most attach directly to the lift and run fine on a standard household circuit — worth asking about if a shop consultant hasn’t already brought it up.
Bay Width, Door Clearance, and Column Placement
Suspension work means opening doors wide, hanging wheels off, and sometimes rolling a creeper or a floor jack around the lift while a wheel is in the air. That takes more usable width than most people plan for. We ask for the full width and depth of the bay, plus the distance from the intended column locations to the nearest wall, garage door track, workbench, or support post.
A good rule for hobbyist installs near the border towns we serve is to leave enough clearance on each side that you can fully open both truck doors without hitting a column, and enough depth behind the lift to work a strut spring compressor without banging into a wall. If your garage door track hangs down along the ceiling, that can eat into your column placement options too. Send us a rough sketch with measurements before you order — it takes five minutes and saves a redo.
Site Access for Delivery and the Install Crew
Getting the auto lift into your garage is its own logistics problem, especially in rural areas along the Iowa-Missouri line where driveways, gravel lanes, and older outbuildings weren’t built with freight trucks in mind. We ask every customer about driveway width, whether there’s a step up into the garage, and whether we’ll have room to maneuver columns and crossmembers without scraping a doorframe.
We also ask if there’s a forklift or equipment on site, because commercial-scale lifts sometimes need one to move components off the truck, while most home-garage installs are fine with our crew and standard tools. If your driveway floods easily, is on a hill, or turns to mud in spring, tell us that up front so we can plan install timing around it. None of this is disqualifying — we’ve installed lifts in some genuinely tight spots — but surprises on install day cost time, and time costs you money either way.
Getting an Honest Quote Before You Commit
The last piece of the checklist is simply talking to someone before you sign anything. A lot of hobbyist buyers get a quote based on a stock configuration, then find out after the fact that their ceiling, floor, or power situation needs an upgrade or a different model. We’d rather ask five extra questions up front — ceiling height, floor thickness, power available, bay dimensions, driveway access — and get you a quote that matches reality.
We also tell first-time buyers what to expect on paperwork: a deposit to get your order moving, a straightforward invoice, and a install date once the equipment and your site are both ready. If you’ve never worked with us before, ask about current promotions — we run them periodically and they can take some of the sting out of freight costs. Whether you’re outside Ottumwa, Bloomfield, or just across the line into Missouri, we’d rather do the site survey conversation now than the change-order conversation later.
