A rolling bridge jack rides on the rails of a four-post or alignment lift and raises the vehicle off its tires, so you can do brakes, suspension, tire and wheel work without moving the car to another bay. Choosing the right one comes down to three things: your lift's runway width, the weight you need to raise, and the lifting style you prefer (air/hydraulic or manual).
Start with your lift. Bridge jacks are built to a specific runway spacing, so the make, model and capacity of your four-post or alignment lift decide which jack frames will fit. Our fitment calculator matches the two for you, and every jack we sell is guaranteed to fit the lift you tell us about.
Next, size the capacity. Pick a jack rated for at least the heaviest axle you lift, not the whole vehicle. Passenger car and light truck shops usually run 6,000 to 9,000 lb jacks, while fleet, bus and heavy truck shops step up to 15,000 lb and beyond.
Finally, choose the lifting style. Air/hydraulic jacks lift fast with shop air and are the most common choice in busy bays. Look for features such as mechanical safety locks, sliding arm extensions and adapter kits that match the vehicles you service most.
A rolling bridge jack sits on the runways of a four-post or alignment lift and raises the vehicle off its wheels so the suspension hangs free. It lets technicians do brake, tire, suspension and alignment work on the lift without a second lift or jack stands.
Fit depends on your lift's make, model and runway spacing. Use the Rolling Jacks fitment calculator or call 1-800-951-5156 with your lift details, and we will match a jack that is guaranteed to fit.
Choose a capacity at or above the heaviest axle you plan to lift. Most car and light-truck shops use 6,000 to 9,000 lb jacks; heavy truck and fleet shops use 15,000 lb and higher.
Air/hydraulic jacks lift faster with less effort and suit high-volume bays with shop air. Manual hydraulic jacks need no air supply and suit lower-volume or mobile setups.
