AFF 545SD Air Hydraulic Axle Jack - 30/15 Ton 2-Stage
If your shop handles heavy trucks, drop axles, or fleet equipment, you already know what a bad axle jack costs you - downtime, a crew standing around, and a job that should have taken twenty minutes eating up an hour. The AFF 545SD is a 30/15-ton 2-stage air hydraulic axle jack that doesn't cut corners where it counts. Thirty tons in first stage for loaded tandems and heavy drive axle work. Fifteen tons in second stage when you need the extra vertical travel to reach your lift point. One portable unit that handles the real weight you see every day.
The two-stage design is what separates this pneumatic hydraulic axle jack from single-stage options. First stage delivers 30 tons and 2.91 inches of ram travel - fast, powerful, ideal for heavy lifts. Switch to second stage and you get 5.59 inches of ram travel at 15 tons, which is exactly what you need on drop axles and low-clearance applications that require more stroke. That kind of flexibility keeps one jack doing the work of two for most shops. The low saddle height of 5.92 inches gets under the tight spots without a fight.
American Forge and Foundry has been building shop equipment since 1963, and the 545SD reflects that experience in the details. Double polished chrome pistons reduce oil bypass and prevent ram scoring so your jack holds under severe load conditions. The descent metering valve controls lowering speed - no sudden drops, no surprises. The built-in overload valve shuts things down before damage happens if someone pushes past the rated capacity. And the piston head seal uses an industrial-grade design that provides a superior seal at both low and high pressure.
At 66 lbs. with rear casters and an extra-long locking handle, it positions easily in tight bays and loads onto service vehicles without a second person. Free shipping to the lower 48 and over 300 AFF service centers nationwide means you're covered after the purchase, too. If you're weighing this American Forge and Foundry axle jack against other models in the lineup or have questions about fit for your application, call us and we'll give you a straight answer.

Installation & Setup
The 545SD runs on standard shop air and requires no permanent installation. Connect your air line and you're ready to work. A few things to confirm before you put it under a load:
Air Supply: This jack requires a working air pressure of 116 to 145 PSI (0.8 to 1.0 MPa). Most shop compressors fall in that range - verify your supply pressure before first use.
Surface Requirements: Always position on a solid, level, hard surface. Never use on asphalt, gravel, or uneven flooring where the base can shift under load.
Using the Extensions: The included 1.75" and 3" extensions thread onto the ram to increase maximum lift height. Confirm the load is stable and centered before lifting any time extensions are attached.
Temperature Range: The unit is tested for operation from -13°F to +113°F (-25°C to +45°C), so it handles unheated bays and warm-climate shops without issue.
Descent Control: The integral metering valve controls lowering speed automatically. Do not modify or bypass the descent valve - it's what keeps the load from dropping unexpectedly.
Applications for Air Hydraulic Axle Jacks
This air hydraulic axle jack earns its place across multiple industries. Here's where the 545SD fits best and why:
Drop axles, drive axles, tag axles - the low 5.92" saddle height gets under them all. The 2-stage design means you're covered for both maximum-capacity lifts and longer-stroke work on the same rig, without swapping jacks.
When you're cycling through vehicles all day, you need hydraulic axle jacks that position fast and work reliably under repeated daily use. The rear casters and three-position locking handle cut setup time between jobs.
Farm equipment runs heavy and operates in conditions that aren't kind to tools. The 545SD is tested across a wide temperature range and built with heavy-gauge steel - it holds up in field shop conditions where cheaper axle jacks don't last a season.
At 66 lbs. with rear casters, this is one of the lighter options in the 30-ton class. Mobile techs who need a pneumatic axle jack that loads onto a service van without a struggle will appreciate the compact footprint and removable handle.
If the 545SD isn't quite the right capacity for your application, AFF's lineup covers a wide range. The American Forge and Foundry axle jack 547SD steps up for heavier-duty demands. The AFF 544 44-ton air hydraulic axle jack and the 80/50-ton 2-stage air hydraulic axle jack address the highest-capacity industrial and fleet requirements. For lighter work, the American Forge 565E 22-ton air hydraulic axle jack or the 2235 air hydraulic axle jack may be a better fit. Call us and we'll help you narrow it down.

Frequently Asked Questions
What air pressure does the AFF 545SD require?
The 545SD requires a working air pressure of 116 to 145 PSI (0.8 to 1.0 MPa). Most standard shop compressors operate within this range. Verify your supply pressure before first use to ensure proper function and safe operation.
What's the difference between the 30-ton and 15-ton lifting stages?
The two stages offer different combinations of capacity and stroke. First stage gives you 30 tons of lift with 2.91 inches of ram travel - ideal for heavy axle work where maximum capacity is the priority. Second stage reduces capacity to 15 tons but extends ram travel to 5.59 inches, which is useful for drop axles and other low-clearance applications that need more vertical reach. Both stages share the same 5.92-inch low saddle height.
Does the 545SD come with extensions, and how are they used?
Yes. The jack includes a 1.75-inch extension, a 3-inch extension, and a saddle adapter. The extensions thread onto the ram to increase maximum lift height beyond the jack's standard range. Confirm the load is stable and centered before beginning any lift when extensions are in use.
What does the AFF warranty cover on the 545SD?
AFF provides a one-year limited warranty covering defects in material and workmanship. If the jack is found defective within that period, AFF will repair or replace it at no charge when returned prepaid with proof of purchase. The warranty does not cover damage from accidents, overloading, abuse, or modifications. Over 300 authorized service centers are available nationwide for warranty service and parts.
Does the AFF 545SD ship free, and which states are covered?
Yes - the AFF 545SD ships free to the contiguous lower 48 states with no freight charges at checkout. For questions about your specific order or delivery timeframe, call us at (855) 498-2147.
