Storage is a different job from servicing
A lift chosen mainly for mechanical work prioritises access to wheels and the underside. A storage lift prioritises simple loading, stability, usable parking below and how the vehicles sit for long periods. That is why 4-post is usually the natural starting point.
Calculate the stack, not just the lift height
Measure the actual height of both vehicles and the lowest ceiling obstruction. The upper vehicle must clear the ceiling while the lower vehicle must fit beneath the raised runways with a sensible margin. Garage doors and tracks are common constraints.
Check length as carefully as height
The runways must suit the wheelbase and the garage must accommodate the lift structure, approach ramps and vehicle manoeuvring. A nominally wide garage can still be too short for a comfortable storage installation.
Decide whether you also want to service cars on it
A 4-post lift supports the vehicle through its tyres. If you want wheels-free brake or suspension work, check compatible jacking beams or other manufacturer-approved solutions and include them in the budget.
Garage Equipment Association vehicle lift buying guidance describes 4-post lifts as a common home-garage option and particularly suitable for longer-term storage. Final dimensions, loading and installation requirements remain product-specific.
Vehicle lifts are safety-critical equipment. GarageReady is decision support, not structural or installation approval. Confirm the final specification with the manufacturer and a competent installer.
