American Forge and Foundry Floor Jack - 5 Ton Air/Hydraulic Long Chassis
When you're running a busy shop and pushing through trucks, buses, and heavy equipment all day, a bargain-bin jack isn't just annoying - it's a liability. The American Forge & Foundry AFF 3125 is the 5 ton hydraulic floor jack built for shops that can't afford downtime. Heavy-gauge steel frame, precision-machined hydraulics, UV powder-coated finish, and double-sealed cylinders that won't weep fluid after a year of hard use. This is what commercial-grade actually means.
That 56" long chassis isn't a marketing number. It solves a real problem. Vehicles with extended overhangs, long wheelbase trucks, and full-size vans leave most standard jacks scrambling for a lift point. The extra frame length gets the saddle under the chassis cleanly, without awkward repositioning or wrestling the jack into position. Combined with a 6" low profile entry and a 22-1/2" max height, you've got the range to handle almost everything that rolls into your bay.
The air/hydraulic pump runs at 115-200 PSI and pulls 7.8 CFM from your shop air line, which means you're raising a full load fast - foot pump engaged, vehicle up, done. No slow hand-pumping cycles. And if shop air isn't available, the jack operates manually so you're never stuck. The handle-mounted locking control lever locks into three positions, letting you dial in your under-car angle before you commit. That's the kind of detail that matters when you're working tight in a crowded bay.
AFF has been at this since 1963. Over 300 service centers nationwide and a full replacement parts inventory mean this isn't a throw-away purchase - it's a tool you can actually keep running. Replacement parts are available, support is accessible, and it ships free to the lower 48. Call us if you have questions before you order.

Installation & Setup
Air Supply Requirements
This is an air/hydraulic long chassis floor jack. To take full advantage of the pneumatic assist pump, your shop needs a compressed air supply delivering 115-200 PSI at a minimum of 7.8 CFM. Most standard shop compressors in a professional service environment will meet that spec. Connect your air line to the jack's inlet fitting and you're ready to lift at full speed.
Manual Fallback Operation
No air on hand? No problem. The AFF 3125 is fully operable as a standard hydraulic floor jack when shop air isn't available. The foot-operated pump takes over, so you're never dead in the water because of a compressor issue or working on a remote job site.
Control Lever Positioning
The locking control lever mounts on the handle and locks into one of three positions. Before you slide the jack under the vehicle, set the lever to the angle that makes sense for your approach. That extra positioning flexibility saves you from awkward reaching and lets you work more safely in tight spots.
Casters and Maneuvering
Full-rotating swivel casters handle maneuvering in confined shop spaces. At 273 lbs shipping weight, this jack is substantial - plan for two people when moving it off the pallet or repositioning it from one bay to another.
Applications
Built to ANSI commercial quality truck jack standards, the AFF 3125 is purpose-matched for fleet shops running medium and heavy-duty trucks, transit buses, and service vehicles day in and day out.
Five tons of capacity handles the kind of equipment that laughs at a standard automotive jack. If your shop services construction or ag equipment, this is the 5 ton air hydraulic floor jack that belongs on your floor.
Full-size pickups, crew-cab long-bed trucks, cargo vans, and stretched chassis all benefit from that 56" long chassis service jack frame. The saddle reaches lift points that a shorter jack simply can't access cleanly.
Shops running back-to-back lifts need equipment that keeps up. The air assist pump combined with foot-operated controls means fast, repeatable cycle times without hand fatigue from manual pumping all shift long.
AFF products are deployed in military, agriculture, and demanding industrial environments worldwide. The commercial-grade build and ANSI compliance translate directly to high-load, high-frequency applications beyond the typical garage.
The dual-mode operation - pneumatic when air is available, manual hydraulic when it isn't - makes this a practical choice for shops with intermittent compressor access or field service situations.

Frequently Asked Questions
Can the AFF 3125 be used without a compressed air supply?
Yes. The AFF 3125 is designed to operate in both pneumatic and manual hydraulic modes. When shop air is connected at 115-200 PSI (7.8 CFM), the air assist pump handles lifting quickly and efficiently. When air isn't available, the foot-operated manual hydraulic pump takes over and the jack works just like a standard floor jack. You're never dependent on having a compressor running to use it.
What size air compressor do I need to run the pneumatic assist?
The jack requires a compressed air supply in the 115-200 PSI range at a flow rate of 7.8 cubic feet per minute (CFM). Most professional shop compressors in a commercial service environment will meet or exceed that spec. If you're unsure whether your compressor is up to it, check the CFM output at the operating PSI range before connecting the jack.
Why is the 56" long chassis important - does it matter for most vehicles?
It matters a lot for certain vehicles. Standard floor jacks work fine under passenger cars and most SUVs, but extended-wheelbase trucks, full-size long-bed pickups, crew-cab configurations, cargo vans, and buses often have lift points that a shorter jack can't reach without difficult repositioning. The 56" frame gets the saddle under those vehicles cleanly on the first approach. If your shop regularly services larger fleet vehicles or heavy-duty trucks, the long chassis saves real time and removes a real frustration.
What does the 1-year warranty cover and how do I make a claim?
The AFF limited warranty covers defects in material and workmanship for one year from the date of purchase. If the jack is determined to be defective, AFF will repair or replace it at no charge - you'll need to ship it prepaid along with proof of purchase to AFF or an authorized service depot. The warranty does not cover damage from accidents, overloading, abuse, or use of non-approved attachments. With over 300 service centers nationwide, finding an authorized depot is usually straightforward. Call us at (855) 498-2147 if you need help locating one.
How does this jack ship and what should I expect on delivery?
The AFF 3125 ships free to the contiguous lower 48 states. At 273 lbs, it will arrive on a freight pallet - this is not a parcel delivery. Plan to have help available when the freight carrier arrives, and inspect the pallet and packaging carefully before signing for it. If you have any questions about delivery logistics or lead times, call us at (855) 498-2147 before placing your order.
