View full detailsRolling Bridge Jacks is the dedicated bridge jack catalog for 4-post lift owners. 21 rolling bridge jacks from AMGO, Triumph, Atlas, and Tuxedo. Air-hydraulic and pneumatic operation, 6,000 to 20,000 lb capacity, sliding or fixed-position designs. Every bridge jack lifts wheels off the runways so you can do tire, brake, and wheel service on a 4-post lift.
Air-hydraulic bridge jacks use shop compressed air (typically 90-120 PSI) to raise the jack; the jack itself operates hydraulically. Pneumatic bridge jacks use air pressure throughout. High-mount vs. low-mount variants determine where the jack rides on the 4-post runway. ALI-certified options from Atlas preserve lift certification. Prices from $1,600 AMGO RJ-6A entry through $3,375 AMGO RJ-20A flagship 20,000 lb.

Four reasons to add a bridge jack to your 4-post lift.
4-post lifts hold the vehicle by tires. Bridge jacks raise the wheels off the runways so you can rotate tires, service brakes, and do wheel alignment.
Air-hydraulic bridge jacks tap shop compressed air to raise the jack. Fast, quiet, and no manual pumping required.
Atlas bridge jacks are ALI-certified. Preserves your 4-post lift's ALI certification for shops that require compliance.

Common questions on 4-post bridge jacks.
Bridge jacks raise the vehicle's wheels off the 4-post lift runways so you can do tire, brake, and wheel service. Without a bridge jack, wheels stay on the runways and can't be spun.
Air-hydraulic: shop compressed air raises the jack; hydraulic cylinder does the lifting. Faster, quieter, more capacity. Pneumatic: air pressure throughout. Simpler design, lower cost, slightly slower.
Bridge jack capacity should match or exceed your typical vehicle weight (not the lift's capacity). Cars: 6K-8K lb. Trucks/SUVs: 8K-10K lb. Heavy-duty trucks: 15K-20K lb.
High-mount bridge jacks ride higher on the runway; low-mount ride lower. Choose based on your 4-post lift's runway design. Not all bridge jacks fit all 4-post lifts.
If your shop requires ALI-certified lifts (typically for insurance or fleet contracts), use ALI-certified bridge jacks (like Atlas RJ7000) to preserve certification. Non-ALI bridge jacks void ALI certification.
90-120 PSI shop compressed air, typically 4-8 CFM demand. Most auto shop compressors handle this easily. See Air Compressors for compressor sizing.
Bridge jacks are typically brand-agnostic but check runway spacing and mount height. Every product page lists fitment. Call (470) 208-2754 with your lift model for confirmation.
All bridge jacks ship LTL freight with liftgate service. Free U.S. shipping. Typical delivery 5-10 business days.
Standard manufacturer warranty. AMGO/Triumph/Atlas/Tuxedo typically 1-2 years on structural, 6-12 months on hydraulic components. Pitstop Pro handles claims.
Yes. Bridge jacks are typically self-installed by the shop owner. Install involves attaching the jack rails to the 4-post runways and connecting the air line. 1-2 hours install time.
