Building a dealership service department without a complete service bay equipment list is like framing a house without a materials list. You end up making decisions on the fly, forgetting critical items, and discovering gaps after the concrete is poured and the walls are up. The equipment determines the electrical load, the air capacity, the concrete depth, the ceiling height, and the bay dimensions. Every one of those specifications must be locked before construction begins. For comprehensive guidance, see our dealership service department best practices resource.
We are Auto Lift Services, and we spec the complete equipment package for dealership service departments before the architect draws the first line. We partner with general contractors like our partner construction companies to deliver the entire facility — architecture, construction, equipment, and installation — backed by a two-year warranty on the building and everything in it. The service bay equipment list we build for each project is the document that drives every construction decision downstream.
This is the complete checklist, broken down by bay type, with the specific models, infrastructure requirements, and dimensional specs you need to get right the first time.
General Repair Bay: The Workhorse
The general repair bay handles the bulk of your service volume — brakes, suspension, diagnostics, drivetrain, engine work, and scheduled maintenance. A 12-bay department typically allocates seven to eight bays to general repair. Each one needs the following.
Lift. Two-post lift rated for your vehicle mix. The Challenger CL10V3 at 10,000 lbs handles passenger cars and light trucks. The Challenger CL12A at 12,000 lbs covers everything through full-size trucks and SUVs. For a mixed-franchise dealer servicing both sedans and three-quarter-ton trucks, the CL12A is the safer spec. Rotary SPOA series is the alternative for dealers who prefer overhead activation.
Workbench and tool storage. A minimum 6-foot steel workbench with pegboard or slat wall backing for hand tools. Under-bench storage for fluids and consumables. Each bay should be self-contained — techs should not share bench space or walk to a central tool room for daily-use items.
Compressed air. Dedicated air drop with filter/regulator/lubricator (FRL) assembly at each bay. Minimum 90 PSI at the point of use with 15 CFM sustained flow for impact wrenches. The main system should be sized for simultaneous demand across all bays, not average demand.
Exhaust extraction. Overhead hose reel exhaust extraction system with magnetic tailpipe adapter. Required by OSHA in enclosed bays. The reel retracts the hose when not in use, keeping the floor clear.
Electrical. Minimum four 120V duplex outlets per bay for diagnostic tools, work lights, and battery chargers. One 208V or 240V circuit for the lift. Outlets should be wall-mounted at 42 to 48 inches — not floor level where they collect fluid and debris.
Lighting. 100 foot-candles minimum at the work surface, per IESNA recommendations for automotive repair. LED high-bay fixtures are the standard. Supplement with task lighting at the workbench. Poor lighting slows diagnostics, increases errors, and contributes to eye fatigue over long shifts.
Floor drain. Each bay or every two bays should have a floor drain connected to an oil-water separator. The separator is a code requirement in most jurisdictions. Drain placement should be directly under the lift center point where fluid spills are most likely.
Concrete. Minimum 6-inch slab, 4,000 PSI, with rebar or fiber reinforcement. Surface-mounted two-post lifts concentrate load on the anchor bolts — the concrete must meet the lift manufacturer’s specification for thickness and compressive strength. For inground lifts, the pit excavation and pour specifications are entirely different and must be engineered per the lift model.
Bay dimensions. Minimum 12 feet wide by 24 feet deep for a standard two-post bay. Add 2 feet of width for comfortable door swing clearance on both sides. Ceiling clear height minimum 12 feet for passenger vehicles, 14 feet if servicing trucks with accessories.
Alignment Bay: Precision Equipment, Precision Floor
The alignment bay is the highest revenue-per-square-foot bay in the department. It requires equipment and infrastructure that general repair bays do not, and every specification must be tighter. (See also: dealership alignment bay.)
Lift. Alignment-ready lift — either a four-post drive-on or a flush-mount scissor lift with integrated turnplates and slip plates. The lift must be designed for alignment work from the factory. Retrofitting turnplates onto a general-purpose lift introduces measurement error and slows every alignment.
Alignment system. Hunter HawkEye Elite with camera bridge. This is the industry standard for speed and accuracy. The camera bridge mounts above the lift and requires specific ceiling height and structural attachment points. Network connectivity is required for software updates and data transfer to the DMS.
Turnplates and slip plates. Integrated into the lift platform or recessed into the floor. Turnplates allow the front wheels to pivot freely during alignment readings. Slip plates on the rear allow lateral movement. Both must move without resistance — binding or sticking turnplates produce inaccurate readings.
ADAS calibration space. Advanced driver assistance system calibration requires 25 to 30 feet of clear, unobstructed space in front of the vehicle for camera and radar target positioning. This is a building design requirement — the space must exist in the floor plan. ADAS work is growing rapidly and dedicating this space now avoids a costly retrofit later.
Floor flatness. The alignment bay floor must be flat within 3mm tolerance across the entire lift platform area. Standard concrete finishing is not sufficient. The contractor must use a precision screed and verify with a straightedge. An out-of-spec floor produces inaccurate alignment readings on every vehicle, leading to comebacks, customer complaints, and wasted labor.
Controlled lighting. Glare and shadows interfere with camera-based alignment systems. Diffused LED lighting without direct-beam fixtures aimed at the lift area produces the cleanest readings.
Revenue context. A single alignment bay running eight to ten alignments per day at $120 to $150 each generates $220,000 to $375,000 per year. High-volume dealers running 20 or more alignments per week need two bays — one bottlenecked bay means pushing work to tomorrow, and tomorrow is already sold.
Tire and Wheel Bay: High-CFM, High-Throughput
A dedicated tire and wheel bay keeps tire work from tying up general repair bays where higher-margin work should be flowing. The equipment list is specialized and the compressed air demand is the highest in the building.
Tire changer. Hunter leverless tire changer. Leverless technology eliminates rim contact during mounting and demounting. This is not optional for dealerships servicing premium vehicles — a single scratch on a $500 alloy wheel costs more than the price difference between a leverless machine and a conventional one. Rim damage claims run $500 to $2,000 per incident on alloy and forged wheels.
Wheel balancer. Hunter road force balancer. Standard spin balancers compensate for weight imbalance. Road force balancers also detect tire uniformity issues — radial and lateral force variation — that cause vibrations standard balancing cannot solve. GM has required road force balancing capability at every dealership since 2017. This is an equipment specification that OEM compliance may dictate.
TPMS programming tool. Every tire service involves TPMS sensors. A universal TPMS tool that programs, clones, and relearns sensors for all makes avoids the delays and limitations of brand-specific tools.
Bead blaster. For seating tubeless tire beads that will not seat with standard inflation. Common on low-profile performance tires and truck tires.
Wheel lift assist. Ergonomic wheel lift for tires over 50 lbs. Reduces back injuries and speeds handling of truck and SUV tire and wheel assemblies. This is a worker safety item as much as a productivity item.
Compressed air. Tire work is the highest-CFM bay type in the department. Impact wrenches, bead blasters, and inflation all demand sustained high-volume air. Size the compressor and distribution for simultaneous demand in the tire bay plus normal demand across the rest of the shop. An undersized air system turns your tire bay into a bottleneck every time someone uses an impact gun in another bay.
Layout note. Tire bays should be positioned near the express service lane and the parts window for tire inventory access. Tire storage staging — both new tires waiting for installation and customer seasonal storage — needs dedicated floor space adjacent to the bay.
Express Service Bay: Speed Is the Specification
Express bays are designed for volume — oil changes, rotations, inspections, and fluid services in 30 minutes or less. Every piece of equipment is chosen for cycle time, not versatility.
Lift. Drive-on lift or mid-rise scissor lift. Drive-on lifts eliminate the arm positioning time of a two-post lift. The vehicle drives on, the tech raises it, and work begins. Time from entry to vehicle in the air: 15 to 20 seconds versus 60 to 90 seconds on a two-post. At 40 vehicles per day, that difference is 30 to 50 minutes of recovered production time.
Bulk fluid system. Overhead reel dispensing connected to bulk oil, transmission fluid, coolant, and DEF storage. Individual quart bottles are the enemy of express throughput. Bulk systems eliminate bottle handling, reduce waste, and track every ounce dispensed per vehicle.
Waste collection. Waste oil drain with overhead reel, waste coolant capture, used filter collection. All waste streams need dedicated containers that can be serviced without disrupting bay operations.
Inspection tools. Battery tester, tire tread depth gauge, brake measurement tool, and digital inspection tablet or software. The express bay is the front door to your service department — every vehicle entering is an opportunity to identify additional work. The service bay equipment list for an express bay should include everything needed to generate a complete multi-point inspection report before the oil change is finished.
120V outlets. Diagnostic tools, inspection tablets, and battery chargers. Express bays are lighter on electrical demand than general repair but still need convenient outlet placement.
Drive-through capability. The ideal express bay allows vehicles to enter from one end and exit from the other without reversing. This eliminates backing maneuvers in the drive aisle and keeps the line moving. Building design must accommodate this with through-wall openings and separated entry and exit lanes.
Heavy-Duty Bay: Bigger Everything
If you service medium-duty trucks, commercial vehicles, or fleet units over 10,000 lbs GVWR, you need at least one heavy-duty bay. The service bay equipment list scales up across every dimension.
Lift. 18,000 lbs minimum — PKS or Challenger heavy-duty platforms. Commercial fleets with Class 4 to 6 trucks may need 30,000 lb capacity. The lift selection must match the heaviest vehicle you will service, not the average.
HD tire changer. Truck tire changers rated for 17.5-inch to 24.5-inch wheels. Standard passenger car tire machines cannot handle the bead seating force or wheel diameter of commercial tires.
Bay dimensions. Minimum 14 feet wide by 30 feet deep. Wider bay doors — 12 feet minimum, 14 feet preferred. Standard 10-foot doors will not clear a dually pickup or a box truck with a lift gate.
Ceiling height. Minimum 18 feet clear to accommodate the vehicle on the lift at full rise. A standard 14-foot ceiling that works for passenger cars will not clear a van or truck body at maximum lift height.
Concrete. Heavier vehicles concentrate more force on the floor and the lift anchors. The concrete specification for a heavy-duty bay is typically 8-inch slab, 5,000 PSI minimum, with engineered reinforcement per the lift manufacturer’s requirements.
Electrical. Heavy-duty bays often need 480V three-phase power for large commercial lifts and associated equipment. Plan the electrical panel capacity during design, not during installation.
Exhaust extraction. Diesel exhaust extraction requires higher-capacity systems than gasoline vehicle bays. The extraction hose diameter and blower CFM must be sized for diesel particulate and volume.
The List Comes Before the Building
Every item on this service bay equipment list has a corresponding construction specification — a concrete depth, a ceiling height, an electrical circuit, an air line, a drain location, or a floor tolerance. Change any equipment decision after construction starts and you are either tearing out work already done or living with a compromise for the next 20 years.
We build the complete equipment package first. We spec every lift, alignment system, tire changer, balancer, AC machine, brake lathe, and air compressor for the specific bay mix and vehicle types the department will serve. Then we hand the construction team the dimensional requirements, anchor templates, utility loads, and floor specifications that turn an equipment plan into a building plan.
We carry Challenger, Rotary, and PKS lifts. We install Hunter alignment, tire, wheel, and brake equipment. We supply RobinAir, Mahle, and Rotary AC machines. And we warranty the building and every piece of equipment in it for a minimum of two years with our GC partners.
If you are planning a new service department or remodeling an existing one, the equipment list is the first document that should exist. Not the architectural rendering. Not the site plan. The equipment list. Everything else follows from it.
