If you are comparing Lift Giant’s four-post and two-post car lifts for a home garage, the right choice depends on space, storage goals, and how you plan to use the lift day to day. Below, we break down the key differences using the questions most buyers ask before installing a lift at home.
Minimum Concrete Slab Thickness for 2 Post Lift vs 4 Post Lift Home Garage
Both Lift Giant models require a 200mm thick concrete base for installation.
- A two-post lift transfers load through its anchored posts.
- A four-post lift spreads the load over four columns and runways.
In both cases, a solid 200mm slab with good reinforcement is essential for safety and compliance.
Required Ceiling Height for Stacking Two Average Cars on 4 Post Lift
For stacking two standard vehicles in a home garage, ceiling height matters.
Our four-post lift provides 1900mm lifting height to the top of the platform. That means in most cases you’ll need around 3.3m to 3.6m ceiling height to stack two average cars comfortably.
A two-post lift’s 2100mm lifting height gives a fraction more rise if ceiling height is limited.
Footprint Comparison: 2 Post vs 4 Post Lift Space Required
Two-Post Lift Footprint (Approx.)
- Width: 2555mm
- Platform length: 3927mm
- Clear floor under platform
- Daisy chain design reduces spacing between adjacent lifts
Four-Post Lift Footprint (Approx.)
- Width: 2601mm
- Platform length: 4000mm
- Total length (excluding ramps): 4245mm
- Four columns and longer runways

Installation and Anchoring
Can a 4 post lift be installed without anchoring to the floor?
For long-term safe use in a home garage, anchoring to 200mm thick concrete is required. While four-post lifts distribute load, floor anchors prevent shifting, rotation, or movement over repeated use.
Do I Need a Rolling Bridge Jack for a 4 Post Lift Home Use?
If your purpose is storage only, no rolling bridge jack is needed. But if you want to work on wheels, suspension or brakes, our scissor jacking beam is recommended. This accessory allows you to raise individual vehicle axles safely while on the four-post.
Time Required to Safely Load a Car: 2 Post vs 4 Post
Both lift types are easy to drive onto and designed for simple, safe positioning.
- 4 Post Car Lift: Drive straight on via the up ramps, position the vehicle, and lift. Ideal for quick everyday parking and stacking.
- 2 Post Car Lift: Also features a full-width drive-on platform with up ramp, making loading just as straightforward.
Where the two-post lift stands out is accessibility. Because there are no front posts and the floor area underneath is clear, you can drive straight through beneath the raised vehicle to access another parking space. This makes it especially effective when installing multiple lifts in a row, as it improves flow and maximises storage within a tighter footprint.
For home garages where space efficiency matters, that clear-through design can make a noticeable difference.
Safety Comparison Table
| Safety Aspect | 2 Post Lift | 4 Post Lift |
| Locking Mechanism | Electronic lock system | Mechanical safety lock |
| Limit Switch | Yes | 24V upper limit switch |
| Long-Term Storage | Yes | Yes |
| Stability | High (anchored) | Very High (4 supports) |
| Best For Vehicle Work | Not Suitable | Use scissor jacking beam (add on) |
Is a 2 Post Lift Safe for Long Term Car Storage?
Yes. When installed on the correct surface and used within its 2300kg capacity, a two-post lift is secure for long term storage. Its reinforced platform and electronic lock provide dependable support.
Best Value Entry-Level 4 Post Lift for Car Enthusiasts
For those focused on practical stacking and simple operation, Lift Giant’s manual release four-post model represents the best value entry-level 4 post lift for car enthusiasts. It’s a strong choice for doubling parking space and storing heavier vehicles.
At Lift Giant, our standard 4 Post Lift is more affordable than our larger and more advanced four-post options – including the XLT 4 Post Lift with Electric Release System, the Double Wide Four Post Parking Lift, the Triple Level Four Post Parking Lift, and the Double Wide Four Post Triple Parking Lift – which are designed for higher capacity, wider bays or multi-level commercial storage and therefore come at a higher price point.
Final Verdict
- Choose a two-post lift if you want excellent space efficiency and vehicle presentation.
- Choose a four-post lift if you need to stack cars, have heavier vehicles or would like the option to work on your vehicles.
