4 Post Alignment

A 4-post alignment lift includes precision-leveled runways, recesses for turn plates under the front wheels, channels for rear slip plates, and a flat reference surface that positions all four wheels at a consistent measured height. Standard service 4-posts may not be level or include these provisions. Alignment work requires all four wheel positions at a known equal height for accurate measurements.

Runway turn plate dimensions and slip plate channels are designed to accept industry-standard turn plates from all major aligner brands, including Hofmann, Hunter, John Bean, and Challenger. Verify the specific turn plate dimensions against your aligner's adapter requirements if using equipment not listed.

This collection covers 11,000 to 18,000 lbs. Most alignment shops use 14,000 to 15,000 lb lifts to handle both passenger cars and light trucks. Confirm your heaviest regularly aligned vehicle — fully loaded — against the rated capacity before selecting.

Yes. Alignment lifts must be installed on level concrete, anchored per the manufacturer's specification, and verified level across all four runways after installation. Even minor runway pitch or cross-slope creates alignment reference errors. Professional installation with a post-installation level check is essential for accurate alignment work.

Yes. Alignment lifts can be used for general service work when not in alignment use. The drive-on runway is suitable for oil changes, general inspection, and any service that does not require free-hanging wheels. For undercarriage work requiring wheels off the ground, a 2-post or scissor lift is more appropriate.

Alignment-rated 4-post lifts typically run 22 to 25 feet in runway length plus 4 to 5 feet of approach clearance at the drive-on end. Width is typically 10 to 12 feet. Plan an additional room beside the lift for the aligner tower and technician workspace around the vehicle.

Many models in this collection carry ALI Gold Label certification. Check the ALI badge on individual listings or filter through the ALI Certified Lifts collection for certified alignment configurations. For dealerships and fleet programs requiring certified equipment, this is the starting point.

Most 4-post alignment lifts operate on 208-230V single-phase power. The alignment equipment itself has separate power requirements — the computer and sensors typically run on 110V. Confirm both the lift and aligner power requirements when planning electrical work for a new alignment bay.
