4-Post & Alignment Lift Installation

4-post lifts are what oil change, muffler, tire, and general service bays run when they need a vehicle in the air without arm swing in the way. The vehicle sits on the runways: drive on, position, raise. An alignment rack is a 4-post built for alignment work, so this page covers both.

Looking for home garage storage instead? That's a different lift and a different job; see storage lift installation. All installation services are on our lift installation page.

4-Post Service Lifts

Wheels stay on the runways for exhaust, oil changes, inspections, and fluid services. Add rolling jacks for wheel-off brake and tire work.

• No arm swing: drive on and go, for faster vehicle cycling in high-volume bays.
• Full undercar access: open from all four sides, with no columns in the way.
• Rolling jacks: optional bridge jacks lift the wheels off the runways. One lift, two capabilities.
• Heavier capacity: commonly 12K to 18K, so trucks, vans, and fleet vehicles are no problem.

We assess the bay, verify the floor handles the load at each post, confirm ceiling clearance for the raised vehicle, and run the electrical. Runway lifts go in fast: most installs take half a day to a full day.

Atlas: 412 (12K) and 414 (14K), commercial-grade runway lifts for service bays. Challenger: 4P14 (14K), 4115 series (15K), and 4018XFX and 44018 (18K), with rolling jack packages, drip trays, and wheel alignment add-ons available.

Running buses, box trucks, or Class 6 to 8 vehicles? Challenger 4-posts from 30,000 to 60,000 lbs are covered on our heavy-duty and fleet lift installation page.

Alignment Racks

Same install fundamentals as a service 4-post, but the precision requirements are tighter: turnplates up front, slip plates in the rear, level runways, and mounting points for your camera or sensor system.

• Floor leveling: the rack has to be dead level, and we shim and adjust until it is. Readings are only as good as the platform.
• Turnplates and slip plates: recessed into the runways, they have to move freely under load and stay calibrated. We set them and verify travel.
• Camera and sensor mounting: Hunter, John Bean, Hofmann, or others need clear sightlines and rigid mounting. We coordinate with your vendor or install the mounts ourselves.
• Approach: vehicles need a straight, level drive-on. If the bay layout won't allow it, we flag it during the site assessment.
