A car lift changes how a collector treats his own vehicles, and we watched that happen over twelve months with a customer in northeast Iowa who owns six cars and a 30×40 pole building. When he called us, he had a specific problem: two of his cars needed shocks and springs, one needed a full rear leaf pack, and he was tired of paying shop labor for work he was perfectly capable of doing himself on his back on a creeper. He also wanted to stack vehicles for the winter so the daily driver wasn’t parked outside in Fayette County snow. What follows is the honest version of his first year — what the install actually involved, what surprised him, and what he’d do differently.
We install across Iowa and ship parts nationwide. Tell us your ceiling height, slab thickness, and heaviest vehicle, and we’ll tell you honestly which model fits your building — and which ones don’t.
The Pole Building That Set the Rules
His shop was a 30×40 with 12-foot sidewalls, a four-inch slab poured five years earlier, and a single 240V circuit already run for a welder. That building dictated almost every decision we made. Twelve-foot sidewalls sound generous until you do the math on stacking: a mid-size sedan is roughly 57 inches tall, the runways and posts eat vertical space, and you need clearance to walk under without ducking. We measured to the underside of the truss, not the wall, because the truss is what actually stops you.
The slab was the bigger question. Four inches of 3,000 PSI concrete is enough for most 8,000 to 9,000 lb four-post units because the load spreads across four base plates rather than concentrating into two. A two-post would have been a harder conversation — those want thicker concrete under each column and a bigger anchor bite. We drilled test cores in two corners, found consistent depth and no voids, and cleared it. He’d been told by a big-box salesman that any garage floor works. That’s not true, and we’ve been called out to fix the consequences. If you’re in a building where the slab history is unknown, get it checked before you buy anything, not after your car lift is sitting on a pallet in the driveway waiting on an install crew.
Why He Chose Four Posts Over Two
He wanted to do suspension work, which is normally an argument for a two-post — free-hanging wheels, unloaded control arms, easy spring compression. But he also wanted to store a car up top with another underneath, and that’s a job a two-post simply cannot do safely for months at a time. So we went four-post and solved the suspension problem with a set of sliding bridge jacks.
Rolling bridge jacks sit on the runways, slide fore and aft, and lift the vehicle by the frame or pinch welds so the wheels drop free. For shocks, springs, control arm bushings, ball joints, and wheel bearings, that gets you 90 percent of what a two-post gives you. The compromise is that you’re working around the runways, and on some unibody cars finding a jack pad that clears the exhaust takes patience. He accepted that trade because storage mattered more. We tell every collector the same thing: pick the configuration that matches how you’ll use the equipment most days of the year, not the configuration that’s theoretically best for one job. If suspension work were 90 percent of his time and storage were an afterthought, we’d have pushed him toward a two-post with the concrete work to support it. It wasn’t, so we didn’t.
Install Day and the Things Nobody Photographs
Install took our two-man crew most of a day. The freight arrived on a semi with a liftgate — worth confirming ahead of time, because a collector with no forklift and a gravel approach can end up with 2,400 pounds of steel he can’t move. We laid out the columns, checked square with a tape and a laser, and drilled anchors. Then came the part that separates a good install from a bad one: leveling.
Nobody photographs shimming. But almost every service call we get for a lift that binds, drifts, or won’t lock evenly traces back to columns that weren’t plumbed and runways that weren’t level within spec. We shimmed three of four base plates on his install. His slab looked flat and had a quarter-inch of fall across the footprint from the original pour — normal, invisible, and enough to make the cable tensions fight each other. We also equalized the four cables, cycled the unit a dozen times unloaded, re-checked cable tension after the initial stretch, and then loaded it with his heaviest vehicle and cycled it again. That final loaded cycle is where problems show up. We have taken over plenty of jobs where an owner installed his own car lift, skipped that step, and called us months later because one corner sits low and the safety locks won’t drop together.
The First Suspension Job: Shocks and Springs on a Ninety-Thousand-Mile Coupe
Three weeks after install he tackled the job that justified the purchase: struts up front, shocks and springs in the rear on a coupe with tired dampers. He sent us photos and a few questions, and it went smoothly enough that he did a second car the following month.
The workflow with bridge jacks is specific and worth spelling out. Raise the vehicle on the runways to a comfortable working height, engage the mechanical safety locks, then position the bridge jacks under the designated lift points and raise until the tires clear. Now the suspension is unloaded and you can compress a spring, unbolt a strut tower, and drop an axle without fighting weight. Two rules we hammer on: never rely on hydraulic pressure alone at any stage, and never let a bridge jack be the only thing holding a vehicle while you’re under it. The runways carry the vehicle; the jacks unload the wheels. He also learned the honest limitation of the setup — coil spring compressors need swing room, and on a four-post you’re sometimes working between a post and a fender. He solved it by parking the vehicle nose-out so the front suspension sat clear of the front posts. Small detail, big difference in frustration.
Storage Stacking Through an Iowa Winter
Come November he did what he’d been planning since spring: put a summer car up top and slid the winter beater underneath. Four-post storage is one of the genuine wins in a cold climate, but it demands more discipline than people expect.
First, the vehicle up top needs to be positioned with the weight distributed across the runways, not with the whole drivetrain hanging over one end. Second, the parking brake gets set and wheel chocks go on regardless — a runway is not a driveway, and Iowa temperature swings will move things. Third, if the unit is going to sit loaded for months, it should be resting on the mechanical locks with hydraulic pressure bled off, not held up by a cylinder. Hydraulic seals are wear items, and holding a static load on pressure for ninety days is exactly how you end up with a slow leak. We got a call from a customer in Florida once with a car stuck in the air on a leaking cylinder and no idea what brand of unit he owned. Nobody wants to be that phone call. Fourth, drip trays. Concrete under a stored vehicle stains, and a leaking valve cover gasket will find the roof of the car below it.
What a Car Lift Actually Did for His Trade-In and Resale Numbers
The part he didn’t anticipate was money. Over that first year he sold two vehicles and traded one, and in all three cases he came out ahead of where he’d have been without the equipment.
Some of that is obvious. Fresh shocks and springs, clean bushings, and no rust-seized suspension components read as a maintained car to any buyer who bothers to look. But the bigger effect was documentation and undercarriage condition. He started photographing the underside of every car — clean frame rails, intact heat shields, no fresh weeping from the shocks — and putting those photos in his listings. Iowa buyers care about rust more than almost anything else, and undercarriage photos taken with the vehicle in the air are worth more than paragraphs of description. He also caught two problems early because he was looking at the underside monthly instead of annually: a leaking rear differential seal and a rusted brake line that would have failed inspection. Fixed cheap, both of them. Across three transactions he estimated the swing at several thousand dollars, plus roughly a dozen shop visits he simply didn’t make. He hasn’t paid the equipment off in one year — but the math is moving in the right direction faster than he expected.
What He’d Do Differently, and What We’d Tell the Next Collector
Asked at the twelve-month mark what he’d change, he had three answers. He’d have gone a foot longer on runways to fit a full-size pickup comfortably. He’d have bought the rolling bridge jacks with the initial order instead of adding them later at a higher freight cost. And he’d have run a second 240V circuit and better lighting before install rather than working around it after.
Our advice to the next collector in northeast Iowa is shorter. Measure to your truss, not your wall. Get the slab verified. Decide honestly whether storage or service is your priority, because that answer picks your configuration. Buy the accessories up front. And plan on maintenance being real: cable inspection and tension check, lock mechanism function test, hydraulic fluid level, and a look at every anchor at least annually. We stock cables, locks, cylinders, and power units for every major brand, and you can find parts through our parts lookup. If you’re weighing configurations, our comparisons of two-post versus four-post and our guide to ceiling height requirements cover the details. A car lift is a fifteen-to-twenty-year purchase if it’s installed right and maintained. Done wrong, it’s a liability sitting over vehicles you care about.
