A collector outside Cedar Rapids called us about eighteen months ago with six vehicles, a three-car detached garage, and a bad back. He wanted to stack two cars to free floor space, but what he really wanted — and did not say until our second conversation — was to stop doing brake jobs on jack stands. That combination pushed him toward a car lift automotive setup built around a four-post with a rolling jack rather than a pure storage lift. We did the site survey in November, installed in January, and he has now run a full year on it including two complete rotor-and-pad swaps. Here is what the first year actually looked like, including the parts of the prep nobody warns you about.

The Site Survey: Measuring Before Shopping
He had already picked a model off a website before he called. That is normal and it is almost always wrong. The unit he wanted needed roughly 12 feet of clearance to stack two sedans with a comfortable margin, and his garage measured 10 feet 4 inches to the bottom of the truss chord — with a garage door opener rail hanging another five inches into the middle of the bay. That is a fatal problem for the model he chose and a solvable one for a lower-rise unit with a different lifting height.
A real site survey takes about forty minutes and it measures six things: clear ceiling height at the lowest obstruction, overall bay width, overall bay depth, door header height, slab thickness, and power availability. We also look at slab condition — cracking, spalling, control joint placement, and whether the floor pitches toward a drain. His slab pitched about an inch over the length of the bay, which is common in Iowa garages and completely manageable with shims, but you have to know about it before the truck shows up. Shopping any car lift automotive equipment before you have those six numbers written down is how people end up with a pallet in the driveway and a problem they cannot return.
Ceiling Math, Vehicle Stack Height, and What Actually Fits
Here is the arithmetic we walked him through on a napkin. Take your clear ceiling height. Subtract the height of the tallest vehicle that will go on top. Subtract about 4 to 6 inches of runway and crossmember structure under the top vehicle’s tires. What is left is how tall the vehicle underneath can be, minus a few inches of working margin so you are not scraping a roof.
With 10 feet 4 inches, a 55-inch-tall coupe on top, and roughly 5 inches of runway structure, he had about 63 inches for the bottom vehicle. That fits a low sports car or a sedan with the antenna removed. It does not fit his pickup, which he had assumed would be the bottom car. Realizing that in November instead of in January is the entire value of a site survey. We ended up specifying a four-post rated at 8,000 lb with a lower maximum rise, added a rolling jack so he could get wheels off, and he now stacks the two lowest cars and parks the truck on the floor beside them. Not the plan he started with, but the plan that works in the building he actually owns. Every car lift automotive purchase is a negotiation between what you want and what your ceiling allows, and the ceiling always wins.
Prep Work He Did Himself Before Install Day
We gave him a short list and he knocked out all of it, which cut install time meaningfully. First, clear the bay completely — not mostly, completely, including the shelving on the side wall that would have blocked column placement. Second, sweep and degrease the slab where the base plates land, because we are shimming to level and grit under a base plate is a long-term problem.
Third, power. His unit needed a dedicated 220V circuit and the nearest subpanel was on the opposite wall. He had an electrician run it two weeks ahead, mounted the disconnect where we told him, and left enough whip to reach the power unit position. That single item is the most common reason a home install turns into two visits. Fourth, he relocated the garage door opener rail assembly to a side-mount jackshaft opener — about a half-day job for him — which recovered five inches of centerline clearance and made the whole stack work. Fifth, he cleared a path from the driveway to the bay wide enough for two people carrying a 14-foot runway. That sounds trivial until you are the two people. None of this is glamorous, but prep is the difference between a four-hour install and a wasted day.
Install Day and the First Cycle Test
Install ran about five hours with two techs. Columns set and shimmed to level, crossmembers and runways placed, cables routed and tensioned, hydraulic line run and bled, power unit wired and cycled. The part homeowners always underestimate is cable tensioning — four cables have to be equalized so the runways rise level and the safety locks engage simultaneously. Get it wrong and you get the classic symptom of one corner dropping into its lock a half-second before the others, which is loud, alarming, and hard on the hardware.
We ran it empty a dozen cycles, then loaded it with his heaviest sedan and ran it through full travel with lock engagement at every height. Then we walked him through the daily ritual: visual on the cables, listen for all four locks, never work under a lift that is resting on hydraulic pressure instead of steel. He asked how often to check tension and the honest answer is monthly for the first six months while things settle, then quarterly. Cables stretch a little when new. That is normal on any car lift automotive installation and it is why we schedule a courtesy check-in around the ninety-day mark rather than pretending the job ends when the truck pulls out of the driveway.
The First Brake Job: Rolling Jack Reality Check
Three months in he tackled front rotors and pads on a mid-sixties car with a disc conversion. This is where the rolling jack earns its money, and also where he learned something. A rolling jack on a four-post lets you lift the wheels clear of the runways, but it lifts from frame or pinch-weld points that sit inboard, and on some vehicles — especially older cars and anything with an unconventional frame — you need extra adapters and stacked pads to reach a safe contact point.
He called us mid-job. We walked through his lift points, told him which adapter stack to use, and he finished the fronts that afternoon. The second brake job, on a different car eight months later, took him half the time because he already knew the drill. That is the real first-year arc: the equipment is not hard, but the first time you do anything on it you are slow and slightly nervous. What he said afterward stuck with me — the rolling jack changed the lift from a parking solution into a shop. Working at chest height on a rotor instead of on your back on a creeper is not a luxury when you are past sixty. If brake and suspension work is in your plans, do not treat a rolling jack as an accessory. Spec it with the car lift automotive package from day one.
Year One Maintenance: What Actually Needed Attention
Very little, honestly, and that is the point of buying decent equipment. He topped off hydraulic fluid once at around the six-month mark after the system fully purged air. He re-tensioned cables twice in the first six months, both times minor. He greased the rolling jack slides and the cable sheaves per the manual. He replaced one drip tray that a leaking transmission had eaten through, which is a consumable, not a failure.
The one thing that surprised him was garage humidity. An unheated Cedar Rapids garage swings hard between summer and winter, and he found light surface rust starting on the runway edges by month ten. A wipe-down and a light oil film handled it, but it is worth knowing that a lift in an unconditioned building needs the same corrosion attention you would give any bare steel. We also had him check anchor torque at the one-year mark — all eight came up snug with no movement, which is what you want to see on a properly shimmed install. If you are weighing a car lift automotive purchase for a home garage in Iowa, budget an hour a quarter for maintenance and you will never have a real problem.

Would He Do Anything Differently
Two things, he said. First, he would have measured before he shopped instead of after, which would have saved him three weeks of enthusiasm aimed at a model that was never going to fit. Second, he would have added the caster kit at order time. He skipped it to save money, then spent a Saturday six months later wishing he could roll the whole assembly two feet forward to open a wall cabinet. Retrofitting casters is possible but it is a lot easier to have them on the original order.
What he would not change: buying more capacity than he needed, and buying the rolling jack. The 8,000 lb rating is more than his cars require, but it means the lift is never near its limit and the components are not stressed. And the rolling jack turned a storage rack into a place he actually works. A year in, he has done two brake jobs, an oil change on every vehicle, and a full exhaust replacement he swears he never would have attempted on jack stands. That is a good return.

We would rather tell you no than sell you something that does not fit your building.
