4 post lift size: key dimensions and what they mean

Exterior dimensions determine whether a lift fits between garage walls, under ceilings, and around door tracks. Evaluate these primary dimensions:

• Overall length and runway length. Overall length includes baseplates and approach ramps. Atlas lists the PRO8000 at 206 3/4 inches overall length with approach ramps and 165 3/4 inches runway length. APlusLift lists the 8SXLT at 190 inches overall length, while TRIUMPH lists the NSS8TL at 190 inches overall length and 180 inches runway length. Ensure adequate floor depth so the garage door closes behind the runways.
• Overall width and drive-through clearance. Total width includes external hydraulic pump units. Atlas lists 115 inches width with motor on the PRO8000, APlusLift lists 112 inches on the 8SXLT, and MutsMover lists 108 inches on the 4H850-02. Drive-through clearance between columns measures 99 inches on APlusLift and TRIUMPH models, accommodating cars, trucks, and SUVs.
• Column height and lifting height. Column height sets the minimum vertical clearance needed when lowered. Atlas lists 83 inches column height on the PRO8000; APlusLift lists 94 inches overall height on the 8SXLT. Lifting height dictates under-vehicle clearance: Atlas specifies 67 inches under runways, KATOOL specifies 70.87 inches on the 4-H850, and AUTOKATO lists 84.5 inches on the 4M110PA.
• Runway spacing and vehicle wheelbase. Runway spacing sets usable track width. Atlas lists 74 5/8 inches outside runway to outside runway width and a maximum wheelbase of 153 1/2 inches on the PRO8000, ensuring proper support without tire overhang.

4-post lift dimensions compared: length, width and height specifications

Manufacturer listings occasionally show internal contradictions. TRIUMPH bullets state 190 inches overall length, 94 inches overall height, and 180 inches runway length, whereas its specification table lists 141 inches overall length, 84 inches overall height, and 132 inches runway length. KATOOL titles list an 84-inch lifting height for the 4-H95 while bullets state 79 inches reached in 50 seconds. Always verify dimensions against manufacturer engineering schematics before delivery.

How to measure your garage for a 4-post lift: the step-by-step checklist

1. Measure ceiling height to the lowest obstruction. Measure from the finished floor to the lowest joist, light fixture, or garage door track.
2. Calculate vertical stacking space. Add the lower vehicle height, runway lifting height, runway thickness, upper vehicle height, and roof clearance.
3. Measure bay length with the door closed. Atlas specifies 206 3/4 inches overall length with approach ramps on the PRO8000, while APlusLift specifies 190 inches on the 8SXLT. Maintain walking space around both ends.
4. Check bay width and power unit clearance. Account for external pumps, such as the 115-inch width listed for the Atlas PRO8000.
5. Verify vehicle width against drive-through clearance. Confirm vehicle body and mirror width clear the 99-inch drive-through width listed on APlusLift and TRIUMPH models.
6. Inspect concrete slab integrity. Review the lift maker’s concrete and ceiling requirements. Ensure the slab is level, fully cured, and crack-free.
7. Confirm electrical requirements. Atlas specifies a 110V motor on a 30-amp breaker for the PRO8000, APlusLift uses a 1.5HP 110V motor, and AUTOKATO offers 110V with 220V optional. Always use a licensed electrician to install dedicated shop wiring.
8. Account for caster mobility. Verify the floor is flat without floor drains or steps if moving the lift on rolling casters.

4-post vs 2-post lift size and garage requirements

Deciding between four-post and two-post designs requires balancing bay dimensions against vehicle storage and maintenance goals:

• Floor footprint: A four-post lift occupies a defined perimeter (Atlas PRO8000 measures 206 3/4 by 115 inches; APlusLift 8SXLT measures 190 by 112 inches). A two-post lift concentrates its footprint on two columns, requiring less floor area but wider side clearance for swing arms and vehicle doors.
• Ceiling height demands: Four-post lifts support vehicles by their tires on runways (such as the 165 3/4-inch runways on the Atlas PRO8000), serving as parking stackers when height allows. Two-post lifts lift by the chassis frame, requiring clearance for hanging wheels and overhead crossbars.
• Concrete anchoring demands: Two-post lifts exert large leverage forces on baseplates, requiring strict concrete slab thickness and psi ratings. Four-post lifts spread weight across four posts, allowing freestanding operation with caster kits on many models, though permanent anchoring maximizes rigidity.
• Ease of parking: Driving onto runways requires minimal alignment compared to positioning two-post swing arms, making four-post units faster for daily parking.

Ceiling height and concrete slab considerations

Installing a four-post lift requires checking overhead door travel. Standard garage door tracks curve inward where a raised vehicle sits; installing high-lift tracks or a wall-mounted jackshaft opener recovers critical vertical clearance.

Reviewing lift maker’s concrete and ceiling requirements is essential before delivery. The slab must be level, solid, and free of cracks or expansion joints. When servicing on the floor, place rated stands on solid level ground, follow owner’s manual lift points, and never get under a vehicle on a jack alone. For wheel service on a four-post lift, use an approved sliding jack tray on the runways.

Frequently Asked Questions

What ceiling height is needed for a 4-post lift?

Ceiling height must clear column heights (83 inches on the Atlas PRO8000; 94 inches on the APlusLift 8SXLT) to stand upright. Stacking requires adding lower vehicle height, lifting height, runway thickness, upper vehicle height, and roof clearance.

How long is a typical 4-post car lift?

Overall lengths generally range from 190 inches on the APlusLift 8SXLT to 206 3/4 inches with approach ramps on the Atlas PRO8000.

How wide is a standard 4-post lift?

Overall width ranges from 108 inches on the MutsMover 4H850-02 to 115 inches with motor on the Atlas PRO8000. Drive-through width measures 99 inches on APlusLift and TRIUMPH models.

Can a 4-post lift fit in a standard single-car garage?

Yes, if bay depth and height allow. With widths between 108 and 115 inches on MutsMover and Atlas models, verify side clearance to access vehicle doors and lock releases.

Do you have to bolt down a 4-post car lift?

Caster kits allow freestanding use when unloaded on hobby models, but anchoring to cured concrete maximizes stability and prevents column walk during heavy loading.

What electrical circuit does a 4-post lift require?

Many home lifts use 110V power, though breaker needs vary: Atlas requires a 30-amp breaker for the PRO8000, while APlusLift uses a 1.5HP 110V motor, and AUTOKATO offers 220V optional. Always use a licensed electrician to install dedicated shop wiring.
