A service manager at a dealership near Cedar Falls called us with a familiar problem: three techs fighting over one drive-on rack every time a truck needed exhaust work or a driveline dropped. He wanted a 4 post storage car lift to free up bay space, but he didn’t know whether to buy new or take a chance on a used unit somebody was hauling out of a closing shop. That’s the exact question we get every week, and the honest answer depends on runways, drive-through clearance, and what you’re actually doing on top of it — not just the sticker number.
Compare drive-on capacities, runway lengths, and drive-through configurations before you order. We install and service every unit we sell across Iowa.
What Exhaust and Driveline Work Actually Needs From a 4 Post Storage Car Lift
Exhaust and driveline access isn’t the same job as an alignment rack, and it doesn’t need to be priced like one. What it needs is open, unobstructed underbody clearance the full length of the vehicle, runways wide enough for dual-rear-wheel trucks if that’s part of your mix, and enough rise to stand comfortably under a full-size pickup without stooping. A 9,000-lb capacity 4 post storage car lift covers most dealership service drives, but if you’re running one-ton trucks or box trucks through regularly, you need to check the standard-length runway against XL runway options — that’s a real spec difference, not an upsell.
We’ve quoted this exact configuration for shops moving from a Mohawk 4-post out of service and into a Challenger CL16, and the runway length and drive-through clearance were the first two numbers we pulled, before capacity even came into the conversation. If you’re swapping exhaust and dropping driveshafts all day, you also want a lift with good sightlines down the runway — some frame designs put crossmembers right where you need to stand. Ask for the actual runway drawing before you order, not just a capacity number on a spec sheet.
Used vs New: The Real Decision Framework
We’ve installed plenty of used 4-post lifts pulled out of one shop and reinstalled in another — it’s common enough that we have a standard process for it. The framework we walk customers through: age and duty cycle of the unit, condition of the cables and safety locks, whether the hydraulic power unit matches what’s on the equipment now, and freight logistics, since used lifts usually ship without the manufacturer’s original packaging or documentation. A used 4 post storage car lift can save real money up front, but if the cables are original and the unit’s been in daily service for a decade, budget for a cable and lock inspection at minimum before it goes back into rotation.
New units come with current safety-lock engineering, a warranty, and predictable lead times you can plan a shop schedule around. We tell dealership service managers the same thing every time: if the lift is going into a high-cycle bay running exhaust and driveline jobs all day, new pays for itself in uptime. If it’s occasional overflow storage or a slow bay, a well-inspected used unit is a defensible call. Either way, get the serial number and pull the service history if the seller has one — that tells you more than the paint job does.
Dimensions That Actually Matter for a Dealership Service Drive
Overall length, runway width, and overhead clearance are the three numbers that make or break a 4-post install in an existing bay. Most standard runways run in the 6,000-9,000 lb range with lengths sized for passenger cars and light trucks, while XL runway packages add length for extended-cab and dual-rear-wheel trucks common on a dealership lot. Overhead clearance matters just as much — a fully raised 4 post storage car lift with a vehicle on it needs real ceiling height, and older dealership bays built decades ago don’t always have it.
We measure column footprint too, since driveline work means techs need to walk the full length of the runway without ducking around a column base. Floor flatness matters as well — used equipment moved from a shop with a sloped floor can sit slightly out of level in a new location, and that’s a five-minute fix during install if we catch it, versus a headache later if we don’t. Get us the bay dimensions and ceiling height before you buy anything, used or new, and we’ll tell you straight whether it fits.
Freight, Forklifts, and Concrete: The Install Logistics Nobody Budgets For
Every quote we send for a 4-post install starts with the same three questions: do you have a forklift on site, is there a loading dock or ground-level door, and what’s the condition of the concrete. A 4 post storage car lift ships heavy — the platforms and columns alone can require a forklift to unload, and if the shop doesn’t have one, we add a rental forklift line to the estimate. We’ve built that cost into quotes for shops from Boone to Creston, and it’s rarely the number people expect walking in.
Concrete matters just as much. We need a minimum slab thickness and cure time verified before we anchor a 4-post lift, new or used. If you’re pouring new concrete for the bay, plan the install date around the cure schedule — rushing an anchor set into green concrete is the single most common install delay we see. Tell us upfront if there’s no forklift, no dock, and unknown concrete age, and we’ll build the real timeline instead of guessing and rescheduling a crew.
Storage-Only Versus Full Alignment-Capable: Don’t Overbuy
A straight 4 post storage car lift for exhaust, driveline, and general underbody work does not need alignment-grade rails, turnplates, or slip plates — those features add cost and complexity you won’t use if alignment isn’t the job. We’ve had customers ask us to quote alignment racks by mistake when what they actually needed was a plain storage and service lift, and the price difference is significant enough that it’s worth double-checking the spec before you sign anything.
On the flip side, if there’s any chance the bay will do alignment work down the road, it’s worth pricing the difference now rather than replacing the lift in two years. We ask every customer point-blank: is this lift ever touching an alignment job, or is it strictly storage, exhaust, tire, and driveline? The answer changes the recommendation completely, and it’s a five-minute conversation that saves thousands.
Rolling Jacks, Casters, and the Accessories People Forget to Quote
We’ve had customers order a 4-post lift and only remember rolling jacks or a caster kit after the main quote already went out. Rolling bridge jacks let techs lift a corner or an axle off the runway for tire, brake, or suspension work without a second lift, which matters a lot for driveline jobs where you need a wheel off the ground while the vehicle sits on the platform. If exhaust and driveline access is the primary use, rolling jacks are worth adding from the start rather than as an afterthought change order.
Caster kits are the other item people miss — they let you reposition a 4 post storage car lift within a bay without a forklift, which matters in shops that shuffle equipment seasonally or share space with other services. Drip trays keep the runway clean under vehicles that leak, which every dealership service drive eventually deals with. None of these are expensive add-ons individually, but bundled into the original quote they’re far cheaper than a change order after install.
Warranty, Service, and What Happens After Install
New equipment carries manufacturer warranty coverage on structural components and hydraulics, and that matters more than most buyers weigh it — a cable or lock failure on a loaded 4-post lift isn’t a minor repair, it’s a safety issue. Used equipment typically carries no warranty unless the seller specifically offers one, so factor an inspection and possible parts replacement into the used-lift budget from day one rather than treating it as a surprise later.
Either way, we service what we sell and most of what we didn’t. If you already run a Rotary or Challenger 4-post and just need cables, locks, or a hydraulic power unit rebuilt, that’s a parts and service call, not a new-lift decision. We stock parts for the major brands and can usually turn around a cable or lock order fast enough to keep a dealership service drive from losing a bay for more than a day or two. Call us before you assume a used or aging lift needs full replacement — sometimes it just needs a repair.
