4 Post Lift with Jacks: Bridge & Rolling Jack Guide
Bridge jacks (a.k.a. rolling jacks) turn a storage-friendly 4 post lift into a wheel-free service lift. Here's how they work, manual vs hydraulic, and what to look for before you buy.

TL;DR
- A 4 post lift with jacks gives you both long-term storage and wheel-off service.
- Hydraulic (air-over) bridge jacks are faster; manual hand-pump jacks are cheaper and don't need an air line.
- Match the jack's adjustable width to your lift's runway-to-runway dimension and confirm the rated capacity covers your heaviest axle.
What is a bridge / rolling jack?
A bridge jack is a secondary jack that sits on top of the two runways of a 4 post lift. It "bridges" the gap between them and rolls along their length so you can position it under any factory jack point or axle. Raise the jack and the vehicle's wheels lift off the runways — exactly like a 2 post lift, but with the safety and stability of full runway support underneath.
Wheels-free service
Brakes, tires, rotors, suspension, wheel bearings — all the jobs a plain 4 post can't do.
Keep the storage win
Drop the jacks and the lift is still a drive-on storage platform. No tradeoff.
Safer than floor jacks
The vehicle stays supported by the lift's mechanical locks the whole time.
Manual vs hydraulic bridge jacks
| Factor | Manual (hand pump) | Hydraulic (air-over) |
|---|---|---|
| Typical price | $300–$600 | $700–$1,400 |
| Lifting speed | Slow — many pumps | Fast — seconds |
| Needs air compressor | No | Yes (90+ PSI) |
| Best for | Occasional DIY use | Frequent service, shops |
| Effort | High | Low |
Buying checklist
- Measure the runway-to-runway width on your lift and confirm the jack's adjustable range covers it.
- Pick a rated capacity at least equal to your heaviest axle (typically 3,500–6,000 lbs for cars and light trucks).
- Check that the jack has its own mechanical safety locks — not just hydraulic hold-down.
- Confirm the jack includes stack adapters / rubber pads for factory pinch-weld jack points.
- Katool KT-4H110 / KT-4H850 owners can drop in the Katool 5,000 lb Rolling Bridge Jack — matched runway width and capacity for those models.
- Don't buy a generic floor jack and try to use it on the runways — bridge jacks are built to roll and lock to the runway lip.

Doing your own tires once the wheels are off?
A bridge jack gets the wheels off the runways — but mounting and balancing new rubber still means a trip to the shop unless you own a tire changer. Our sister site reviews the Katool KT-T830 tire changer and KT-B700 wheel balancer combo — the natural next upgrade for a jack-equipped 4 post lift garage.
Picking the right Katool 4 post lift for jacks
Bridge jacks work with every Katool 4 post lift, but heavier-capacity models give you more headroom for trucks and SUVs once a jack adds another vehicle on top of the runways. See our full comparison to pick the right one for your garage.
FAQs
What is a 4 post lift with jacks?
A 4 post lift with jacks is a drive-on car lift that includes rolling bridge jacks — secondary jacks that sit on the runways and lift the wheels off them. This gives you wheel-free access for brake, tire, and suspension work without losing the storage and stability benefits of a 4 post lift.
What's the difference between a bridge jack and a rolling jack?
They're the same thing. 'Bridge jack' and 'rolling jack' both describe a jack that bridges across the two runways of a 4 post lift and rolls along their length so you can position it under any axle or jack point.
Manual or hydraulic bridge jacks — which is better?
Hydraulic (air-over-hydraulic) bridge jacks are faster and easier on your back, but they need an air compressor and cost more. Manual hand-pump jacks are cheaper, work anywhere, and are fine for occasional DIY use. For a home garage that already has a compressor, hydraulic is usually worth it.
Can I add jacks to a 4 post lift I already own?
Usually yes. Most 4 post lifts (including Katool) support add-on rolling bridge jacks sized to the runway width. Check the runway-to-runway dimension on your lift and match it to the jack's adjustable range before buying.
How much weight can a bridge jack lift?
Typical rolling bridge jacks lift between 3,500 and 7,000 lbs — well within the per-axle weight of most cars, SUVs, and light trucks. Always check the jack's rated capacity is at least equal to the heaviest axle you'll lift.
Do I need jacks if I only use my 4 post lift for storage?
No. For pure storage and basic under-car access (oil changes, inspections, detailing), a 4 post lift works fine on its own. Add jacks only when you want to do brake, tire, suspension, or wheel-off work.
