4 Car Lift Buying Checklist for Iowa City Farm Shops

If you run a farm shop outside Iowa City and you’re shopping for a 4 car lift, the biggest mistakes happen before the equipment ever gets delivered. We get calls every month from guys who bought a lift online, got it home, and then discovered their concrete was too thin, their door header was too low, or their power supply couldn’t handle the unit they picked. Auto Lift Services installs and sells lifts across Iowa, and we’d rather walk you through a proper site survey now than show up to a job we can’t safely complete. Here’s the checklist we actually use.

Start With Concrete, Not the Catalog

Every farm shop we’ve visited near Iowa City has slightly different concrete, and that matters more than which brand of 4 car lift you like the look of. Standard poured slabs in this area usually run around 4 inches thick, which is fine for a lot of home-garage lifts but can be marginal for heavier-duty units once you factor in rebar placement, curing age, and any cracking near the anchor zone. Before you buy anything, we ask for the slab thickness, the approximate age of the pour, and whether there’s rebar or wire mesh in it. If you don’t know, that’s okay — we can usually tell from photos or a quick site visit.

If your shop was poured for tractors and trucks rather than a lift, you may still be fine, but we won’t guess. A 4 car lift concentrates a lot of weight onto four small footprints, and undersized anchors in thin or cracked concrete is the single most common reason a lift comes loose or won’t pass inspection. If your concrete is questionable, we’ll tell you honestly whether you need a reinforced pad poured before installation, or whether your existing slab will hold up. It’s a five-minute conversation that saves you from tearing out a lift a year later.

Measure Your Ceiling and Door Height Twice

CV axle and half-shaft work doesn’t require you to drive up onto a second-story lift, but if you’re planning to store a vehicle on top of a 4 car lift while working underneath another one below, you need real headroom. Most 4-post units need 11 to 13 feet of clearance from floor to the lowest overhead obstruction — that includes lights, ductwork, and sprinkler heads, not just the trusses. We’ve had Iowa City-area customers assume they had 12 feet because that’s what the pole barn builder quoted, only to find a light fixture hanging down another foot and a half.

Door height matters just as much, especially if you’re rolling a lifted truck or an SUV with a roof rack through the bay. Measure your actual door opening, not the wall height, and account for the extra inches a vehicle gains once its suspension settles onto the lift’s runways. If your farm shop has a lower door than the rest of the building, that door — not your ceiling — is what determines which 4 car lift model actually fits your workflow.

Know Your Real Weight Rating Before You Call

We ask every caller the same question: what’s the heaviest thing you’ll actually park or work on? For CV axle and half-shaft jobs on farm trucks, loaded pickups, and the occasional tractor attachment hauler, an 8,000 to 9,000 lb rated 4 car lift covers almost everyone in this category comfortably. Don’t size down to save money if you’re routinely dealing with dual-rear-wheel trucks or anything with a snowplow mount — that added front weight adds up fast and a lift rated too light isn’t something you can fix after the fact.

On the flip side, don’t over-buy either. If you’re mostly storing a Jeep, a Camaro, or a couple of daily drivers and doing light service work like CV axle swaps, a lift built for 15,000 lb commercial trucks is overkill and costs more to purchase and install than you need. We’ll talk through your actual fleet — not a hypothetical worst case — and match the rating to real use.

Mobile Kits Aren’t Always the Right Call

A lot of farm shop owners like the idea of a mobile 4 car lift because they picture rearranging the shop seasonally. In practice, once a lift is anchored and wired, almost nobody moves it. Mobile kits add cost and, on some models, reduce stability slightly compared to a bolted, permanent footprint. If your shop layout is genuinely likely to change — say you’re leasing the building or sharing space with another operation — a mobile-capable unit makes sense. If you’re on your own land and this is where the shop stays, we usually recommend putting that money toward a higher weight rating or better surface finish instead.

We’re not against mobile lifts. We sell and install them. We just want you to buy the feature because you need it, not because it sounded convenient during a sales pitch. Ask us directly whether your situation justifies it — we’ll give you a straight answer either way.

Power, Air, and the Stuff Nobody Mentions

Hydraulic 4-post lifts need a dedicated electrical circuit, and most farm shops built years ago weren’t wired with that in mind. Before we schedule install, we confirm voltage, amperage, and whether you’ve got a spare breaker slot close enough to the lift’s planned location to avoid a long, expensive conduit run. If you’re also running air tools for CV axle removal, impact work, or brake service, make sure your compressor and lines reach the bay comfortably — dragging hoses across a shop floor around a loaded 4 car lift is a hazard nobody needs.

This is also the point where we ask about lighting and floor drains. If you’re doing fluid-heavy work like axle and half-shaft service under a vehicle on the lift, a nearby drain or containment plan keeps your shop cleaner and safer. None of this changes which lift you buy, but it changes how smoothly install day goes.

What Delivery and Installation Actually Involve

Once you’ve settled on a model, we schedule delivery and installation as a coordinated visit whenever possible. Our crews check anchor points against your actual concrete on-site, level the columns, run and test the hydraulics, and walk you through safety locks and operation before we leave. If you’re near Iowa City, we handle this route regularly, so freight and install scheduling tend to line up efficiently compared to more remote parts of the state.

If you’re comfortable handling delivery yourself and just need the lift and a phone consultation on install steps, we support that too — plenty of capable farm shop owners prefer to do their own anchoring once we’ve confirmed their site meets spec. Either way, we walk through the same checklist first: concrete, clearance, weight, mobility, and utilities. Get those five things right and the actual purchase decision becomes easy.

Matching the Lift to CV Axle and Half-Shaft Work Specifically

Not every 4 car lift is equally convenient for axle and half-shaft jobs. Look for a deck or runway design that leaves enough clearance around the wheel wells and doesn’t force you to remove a tire just to get a jack or stand underneath. Some 4-post configurations include rolling jacks that ride the runways, which makes lifting one corner of the vehicle for axle removal far easier than trying to improvise with a floor jack balanced on a runway.

If half-shaft work is a regular part of your shop’s business rather than an occasional task, ask us about accessory jack options and caster kits when you’re speccing your unit. It’s a small add-on cost compared to the lift itself, but it changes how much time you spend per job. We can walk you through which packages pair well with the models we stock for farm shops in this size range.
