Every so often we get a call to spec drive on auto lifts for a third-generation family garage in western Iowa where the grandfather built the shop in the seventies, the father added a second bay in the nineties, and the current owner is finally tearing out the old post-lift and doing it right. The one in Council Bluffs we worked with last winter is a good example. They wanted a wheel-bearing-friendly platform, room to store the owner’s project car overhead, and a floor plan that would not force them to rebuild the shop. This article walks through the real dimensions, real sequencing, and real numbers we used, so you can copy the parts that apply to you.

The Council Bluffs Shop and What They Needed
The Council Bluffs shop that pulled us into this project is a two-bay family garage running mostly domestic and Japanese passenger work with a heavy wheel-bearing and brake load. Their old lift was a well-worn two-post that had done its job for eighteen years and was starting to weep hydraulic fluid from a base cylinder seal. When they called us, the owner was clear on two things: he wanted drive on auto lifts because he was tired of the swing-arm dance every time he lifted his daughter’s SUV, and he wanted to store his project truck over top of the working bay so his side of the shop stopped being a museum.
That set of goals is common in family garages once the third generation takes over. The son or the grandson has usually spent time at a dealership on a nice four-post and knows the workflow is faster. The father wants the space efficiency of parking one vehicle over another. And nobody wants to touch the concrete unless they absolutely have to. Our job for the Council Bluffs owner was to hand him drive on auto lifts, a rolling-jack package, and a bay layout that solved all three problems while keeping the original slab intact. We were able to do it. Here are the numbers.
Slab, Ceiling, and the Bay We Were Given
The existing bay was 22 feet deep and 14 feet wide, with a 12-foot 6-inch ceiling to the underside of the trusses. The slab was measured at 4.5 inches with the old post anchors still in it and no visible cracking, which is a normal Iowa two-bay family shop. For a four-post drive on installation you do not need the same 4-inch minimum with fresh 3,000 PSI concrete that a two-post requires, because the four-post spreads the load across four column bases and does not induce the same overturning moment. That said, we still measured, we still verified, and we still document it in writing before we quote. Anchoring is optional on many four-posts as long as the runway is level and the geometry is right, but for a shop that plans to store a vehicle overhead we always anchor.
Ceiling height at 12 feet 6 inches gave us plenty of room for a standard-rise column at roughly 88 inches with a raised runway reaching about 74 inches, plus a project truck sitting on top with about six inches of nose clearance. That was enough to walk under the top-parked vehicle and work on the car below without ducking. We did not need a tall-rise package, and we specifically avoided it because the trusses ran open-web and we did not want a taller column brushing the bottom chord.
Wheel Bearing Service and Why It Drove the Spec
Wheel-bearing work is the reason we spec a rolling jack on every set of drive on auto lifts we install in a family garage. On a two-post you swing arms, lift the car, and pull a wheel. On a four-post drive-on you drive the car on, raise the runways to comfortable height, drop a rolling jack under the front subframe or the rear axle depending on which wheel you are servicing, jack that corner off the runway, and pull the wheel. The mechanics are identical to a two-post, but you get an unlimited length of the vehicle supported on the runway and no risk of a pinch-weld tearing because the car is not resting on two small pads.
The Council Bluffs shop does a lot of front-hub replacements on Ford Explorers, Chevy Tahoes, and Toyota Highlanders. For those the tech drives the SUV on, raises the platform to shoulder height, drops the rolling jack under the front cross-member, jacks the front corner, pulls the wheel, pulls the caliper and rotor, and replaces the hub assembly. Nothing about that workflow is faster on a two-post. And when the wheel goes back on, the car is still on the four-post, the parking brake is still safely on the rear wheels, and there is no risk of a vehicle rolling. That is the honest engineering case for drive on auto lifts in a family garage doing bearing work.
Runway Length and Storage Overhead
Because the family in Council Bluffs wanted to store the project truck on top, we sized the runway to the truck, not to the daily-driver work. The project vehicle was a mid-2000s Chevy Silverado extended cab, roughly 227 inches nose-to-tail. Standard 175 inch runways on a passenger four-post would not have supported it, so we specified a 205 inch runway with a nine thousand pound capacity, and drop-down approach ramps on the front only, since the storage vehicle would live on the platform full-time and did not need a drive-through exit. That single decision saved about 30 inches of overall bay depth compared to a drive-through setup and let us keep the workbench where it was.
For daily service work on the truck at the bottom the shop still gets full access. The runways sit six feet six inches off the floor at max height, which is comfortable working height for a six-foot tech. Underneath, the drive-in clearance with the runway fully raised is about seventy-two inches, meaning the Silverado above still clears any daily driver they roll under. That is the specific dimensional payoff for going with drive on auto lifts as a storage-plus-service platform, and it is why we love them for family shops that outgrew their two-post.
Rolling Jack, Air Line, and Electrical
The Council Bluffs shop had one 20-amp 120-volt circuit in the bay and no air line ran to the lift location. That is the norm in older Iowa family garages. Our four-post specification called for a 20-amp 120-volt outlet within six feet of the power-side column, which we already had, and a quarter-inch air line for the rolling jack, which we ran during install. We ran the air line overhead from the existing compressor closet, dropped a coiled hose over the driver-side column, and terminated it with a quick-disconnect at rolling-jack working height. Total added cost for the air line was under a hundred dollars in parts. No electrical work required beyond the outlet already in the wall.
We also installed the rolling jack itself, calibrated it against the specific pinch-weld pad set the shop uses on their most common vehicles, and left them with a spare pad set for domestic full-frame trucks. Rolling-jack pad sets are cheap and they are the one accessory shops actually lose over the years, so we ship every install with two full sets. When we returned six months later for the first annual inspection the pad sets were intact, the air line was clean, and the family had moved a good ten years of Iowa dirt off the shop floor. That kind of buildout ages well.
Freight, Unloading, and Install Sequence
For every set of drive on auto lifts we deliver to a Council Bluffs shop, we bring our own truck, our own forklift or gantry, and our own crew. The lift arrives palletized, roughly two thousand pounds shipping weight for the columns and runway sections, plus another six hundred pounds for the rolling jack in its own crate. On the day of install we back the truck into the bay opening, forklift the columns off the truck, position them per the layout we drew during the site visit, drop-set the runways, and shim to level. Total install time for a mid-nine-thousand-pound four-post with rolling jack in an existing bay is one full day for the two-tech crew we send.
Sequence matters for a family shop that is still open for work during the install. We schedule installs at the start of the workweek, we ask the owner to move all rolling equipment out of the bay before we arrive, and we ship all the small parts kits ahead by ground so nothing goes missing at delivery. If your slab needs a leveling pour or an anchor patch, we handle that in a separate visit before the lift arrives, so install day is just the lift. That sequence is how we finished the Council Bluffs project in a single Monday, with the family running paying work on the four-post by Tuesday afternoon.
Numbers, Timeline, and How to Start
Total budget for the Council Bluffs project on drive on auto lifts landed in the mid-five-figure range including the lift, the rolling jack, the air-line install, freight from the manufacturer to our Ames warehouse, our own delivery truck run to Council Bluffs, unloading with our gantry, and a one-day install with two techs. That number is honest for a well-specified alignment-ready nine thousand pound four-post with dual jacks, but a base storage-focused four-post without alignment cutouts or a rolling jack runs meaningfully less. We publish current ranges on our store pages and quote firm prices after a bay visit or a video walkthrough.
Timeline from first phone call to a working lift was about five weeks, with the manufacturer lead time being the long pole. If you are anywhere in western Iowa, from Council Bluffs up to Sioux City and out toward Denison, we cover you on a single truck run and we do not charge additional freight beyond what we quote. Call us at 800-674-9302 or email founder@autoliftserv.com and we will get you the same site visit, the same drawing, and the same install crew we sent to Council Bluffs.
