Last winter an overlanding builder in West Des Moines called us with a specific problem: he was outgrowing the crawler jacks and jack stands he’d been using to build his rock-crawling rig, and he needed real auto lifts for home garage exhaust and driveline access on a modified full-size truck. The truck was 24 inches taller than stock, weighed 8,400 pounds curb, and needed constant work on the driveshafts, transfer case, and custom exhaust. His shop was a 40 by 30 pole barn with 14-foot sidewalls and a slab poured two years earlier. This article walks through that install case study from first phone call to first oil change on the finished lift, with every decision we made and why.
From overhead two-posts to four-post storage lifts, we spec the right rig for the build. Call 800-674-9302 for a site survey anywhere in the Iowa corridor.
The West Des Moines overlanding shop that called us last winter
The first call came in on a Wednesday morning. The buyer described his truck, his shop, and his budget, and then asked the question that separates serious buyers from tire-kickers: could we come look at the room before quoting anything? That question told us he was ready to spend money on the right lift, not the cheapest lift. We booked a site survey for the following Monday and arrived with a tape measure, a laser distance meter, a level, and a small concrete impact tester.
His truck was already parked in the bay when we got there. Fenders were flared, the tires were 37 inches, and the roof rack pushed the total vehicle height to about 8 feet 4 inches with the antenna folded. He wanted the truck up high enough to walk under it upright, which meant we needed at least 12 feet of usable lift height plus the vehicle’s own 8 feet 4 inches — putting us near 14 feet total clearance requirement. His 14-foot sidewalls with trusses hitting at 13 feet 8 inches meant we were tight but workable. Auto lifts for home garage builders in his position live and die on this measurement, and getting it wrong means either the roof hits the ceiling or the tech works stooped over. We drew the numbers on his whiteboard and started narrowing the lift list.
Site survey: doors, header height, driveway approach
Ceiling clearance was only one of the survey items. We also measured the overhead door — 10 feet wide by 12 feet tall — which meant the truck cleared with 4 inches of headroom folded. Not great, but workable. The driveway approach was 60 feet of gravel between the road and the door, with a slight rise at the threshold. That mattered for two reasons. First, the freight truck delivering the lift would need to back up that gravel, and 20,000-pound freight trucks don’t love loose surfaces. Second, once installed, the customer would drive the lifted truck in and out over the same threshold every use.
We also inspected the man-door — 36 inches wide, 80 inches tall — to make sure the largest sub-assembly of the lift (the column, 8 feet long) would fit through if we couldn’t get the overhead door open on install day. It did, with an inch to spare on the diagonal. Little things like door widths kill more home-garage lift installs than any other single factor. We’ve seen buyers order online, take delivery in the driveway, and discover the columns won’t fit through any door in the building. When we quote auto lifts for home garage installs, the door dimensions are on the first line of the survey sheet, right next to ceiling height. Get those two right and the rest of the install is mostly execution. Get either one wrong and you’re looking at a return shipment or an ugly workaround with a Sawzall and a header rebuild.
Auto lifts for home garage exhaust and driveline access
The whole point of the project was under-vehicle work. Exhaust systems on modified trucks are custom-fabricated, and every exhaust modification means dropping the exhaust, cutting, welding, hanging, and refitting. The same is true of driveshafts on lifted rigs — angle changes at the transfer case create vibration issues that require repeated adjustment, and every adjustment means dropping the driveshaft. A two-post lift with unobstructed under-vehicle access is the right tool for both jobs, versus a four-post where the driveshaft and exhaust are partially shadowed by the runways.
We specced him a 12,000-pound overhead two-post with asymmetric arms and a low-pad configuration. Asymmetric matters because his door apertures were slightly forward of center on the lifted truck, and asymmetric arms let him open the doors even at full lift height. Low-pad matters because his frame contact points were at custom pinch weld locations he’d reinforced during the build. Standard adapter pads hit those points; taller pads would have missed. Every choice we made was driven by the specific truck he owned, not by a generic spec sheet. Auto lifts for home garage builders working on modified vehicles need this level of custom fit — a stock lift with stock pads works on stock trucks, and everything he owned was a long way from stock. The survey identified those details, and the quote reflected them line by line.
Concrete verification and the core-sample decision
His slab was poured two years earlier by a local contractor. The contractor’s spec sheet said 6 inches of 4,000 PSI concrete, but paperwork doesn’t guarantee reality. We asked if he minded us drilling a small test hole. He didn’t, and we pulled a core sample near where the first column would land. The core came out at 5-3/4 inches thick — within tolerance — and a schmidt hammer read consistent with 3,800 to 4,200 PSI. Good slab.
Not every home-garage slab passes this test. We’ve drilled slabs that showed 3 inches where the paperwork claimed 5, and slabs that read 2,200 PSI where 3,000 was the spec. In those cases, the buyer has three options: pour over the existing slab with an additional 4 to 6 inches of reinforced concrete in a defined pour zone; use longer anchors that reach into the sub-base and epoxy-set them; or move the lift to a different location on the slab. We walk buyers through all three options with real cost numbers, and they pick based on their budget and their timeline. In this case, the slab was fine as-is, and we anchored directly with wedge anchors torqued to manufacturer spec. Auto lifts for home garage installs on questionable slabs are the single biggest cost surprise we see, and a $100 core-sample decision on survey day saves thousands later.
Electrical prep: 220V drop, breaker size, disconnect location
Every serious two-post runs on 220V single-phase power. Motor draw varies by model but typically sits at 20 to 25 amps at 220V during a full lift cycle. That means a 30-amp double-pole breaker and 10-gauge wire, at minimum. The buyer’s shop had a 200-amp subpanel with room for the additional circuit, but the run from the panel to the lift location was 65 feet — long enough that we specified 8-gauge wire to prevent voltage drop.
Local code required a lockable disconnect within sight of the lift, so we installed a 30-amp switched disconnect on the column of the lift itself, wired directly to the motor. That way anyone working on the electrical side of the lift can positively de-energize it before opening the motor box. We also specified a dedicated ground bar back at the panel, because the shop’s original ground was shared across several circuits and we wanted the lift on its own dedicated path. All of this was on the electrical drawing we handed the buyer’s local electrician before the freight arrived. Auto lifts for home garage installs go smoothly when the electrical is done in advance of the lift delivery, not after. Waiting until the columns are up to run wire means extra labor and often extra parts. Plan the electrical during the survey, execute it during the two weeks before delivery, and install day is just mechanical work.
Freight delivery, uncrating, and the first lift
The lift arrived on a Tuesday afternoon on a 26-foot flatbed. Total weight of the crated equipment was 1,850 pounds, split across four crates: two column crates, one carriage-and-arms crate, and one power unit crate. The freight driver had a liftgate but no forklift, so we used the buyer’s neighbor’s tractor with pallet forks to move the crates from the truck into the shop. Total offload time was about 45 minutes with two people plus the tractor.
Uncrating and assembly took a day and a half. We set the columns, ran the anchors, plumbed the columns to vertical within a sixteenth of an inch, connected the hydraulic lines, wired the motor, filled the reservoir with ISO-32 hydraulic fluid, and cycled the lift empty three times to bleed air out of the system. Then we test-lifted a passenger car we’d brought along for the purpose. Everything held. On day three, the buyer drove his own truck onto the arms for the first real lift, and we watched him take it up, drop it into a safety lock at his preferred working height, and stand under his rig upright for the first time in the shop. That moment — customer under his own vehicle, hands free, safe — is what auto lifts for home garage installs are actually about. The rest is just logistics.
What we learned that we now apply to every install
The West Des Moines job taught us three things we now apply to every home-garage install. First, always core-sample the slab if the paperwork isn’t recent and specific. A $100 investment on survey day catches problems that would cost thousands to fix after anchoring. Second, always inspect every door the lift components have to travel through, not just the main entrance. We now measure man-doors, hallway widths, and any low headers between the delivery point and the lift bay. Third, always spec the electrical during the survey and get it installed before the freight arrives. Waiting is the single most common source of delay on install day.
Six months after the install, the overlanding buyer had done two exhaust rebuilds, one full driveline geometry adjustment, and countless oil changes and inspections on his lift. He called us in June for a scheduled service check — cable tension, anchor torque, hydraulic fluid level — and everything was within spec. That’s the outcome we aim for on every home-garage install. If you’re planning a build like his and want a real survey, real numbers, and a real spec-out before you spend money on auto lifts for home garage service, call 800-674-9302. We’ll come look at your room, measure everything that matters, and quote a lift that fits the truck you actually own, not the truck the catalog assumes you have. It’s a longer process than clicking Add to Cart, but the outcome is a lift you’ll use for the next two decades without a single regret.
