The AFF 548SD is a 60\/40\/20 ton three-stage air hydraulic axle jack built for exactly that. Three stages give you flexibility across a wide capacity range without swapping tools. Whether you're servicing a loaded trailer or a lighter fleet vehicle, this American Forge and Foundry jack covers it with one unit.\u003c\/p\u003e\n\u003cp\u003eWhat separates this from cheaper hydraulic axle jacks is what's happening inside the cylinder. The piston head seal borrows from industrial hydraulic technology, giving you a tighter seal at both low and high pressure. That means better hold under severe loads, less creep, and more confidence when you're working underneath. Double polished chromed pistons tighten up tolerances, reduce oil bypassing, and resist ram scoring over thousands of cycles. These aren't marketing claims. AFF tests every unit from -13°F to +113°F and under off-center loading to make sure it holds up in conditions most shops would consider extreme.\u003c\/p\u003e\n\u003cp\u003eThe 54-inch handle locks in three positions so you can maneuver this air hydraulic axle jack into tight spots without fighting it. Integral descent metering keeps the load controlled on the way down, not just the way up. Air-assisted lowering speeds up ram retraction between jobs. And a built-in overload safety valve protects the unit if someone accidentally exceeds capacity. You get two extensions (3\" and 1.75\") plus a saddle adapter right out of the box. If you're comparing this American Forge and Foundry axle jack against other options in the 60 ton axle jack class, the 548SD is the one that doesn't cut corners where it counts.\u003c\/p\u003e\n\u003cp\u003eReplacement parts are available direct through us, and we keep stock on seal kits, piston sets, and cylinder assemblies so you're not waiting weeks if something needs attention down the road. That's the advantage of buying from a shop equipment dealer who actually supports what they sell.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection id=\"specifications\"\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ch3\u003eStage Capacity and Lift\u003c\/h3\u003e\n\u003ctable class=\"gsg-spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e1st Stage Capacity\u003c\/td\u003e\n\u003ctd\u003e60 Tons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1st Stage Low Height\u003c\/td\u003e\n\u003ctd\u003e6.89\" (175 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1st Stage High Height\u003c\/td\u003e\n\u003ctd\u003e9.92\" (252 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1st Stage Lift\u003c\/td\u003e\n\u003ctd\u003e3.03\" (77 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2nd Stage Capacity\u003c\/td\u003e\n\u003ctd\u003e40 Tons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2nd Stage Low Height\u003c\/td\u003e\n\u003ctd\u003e6.89\" (175 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2nd Stage High Height\u003c\/td\u003e\n\u003ctd\u003e12.68\" (322 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2nd Stage Lift\u003c\/td\u003e\n\u003ctd\u003e5.79\" (147 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3rd Stage Capacity\u003c\/td\u003e\n\u003ctd\u003e20 Tons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3rd Stage Low Height\u003c\/td\u003e\n\u003ctd\u003e6.89\" (175 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3rd Stage High Height\u003c\/td\u003e\n\u003ctd\u003e15.91\" (404 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3rd Stage Lift\u003c\/td\u003e\n\u003ctd\u003e9.02\" (229 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eGeneral Specifications\u003c\/h3\u003e\n\u003ctable class=\"gsg-spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHigh Height with Extensions\u003c\/td\u003e\n\u003ctd\u003e15.67\" \/ 18.43\" \/ 21.66\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Air Pressure\u003c\/td\u003e\n\u003ctd\u003e116 to 174 PSI (0.8 to 1.2 MPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHandle Length\u003c\/td\u003e\n\u003ctd\u003e54\" (138 cm), locks in 3 positions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e161 lbs (73 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e165 lbs (75 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Rating\u003c\/td\u003e\n\u003ctd\u003e-13°F to +113°F (-25°C to +45°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSafety Features\u003c\/td\u003e\n\u003ctd\u003eBuilt-in overload valve, integral descent metering\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/section\u003e\n\u003csection id=\"whats-included\"\u003e\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul class=\"gsg-included-list\"\u003e\n\u003cli\u003eAFF 548SD Axle Jack Unit\u003c\/li\u003e\n\u003cli\u003e75 mm (3\") Extension\u003c\/li\u003e\n\u003cli\u003e45 mm (1.75\") Extension\u003c\/li\u003e\n\u003cli\u003eSaddle Adapter\u003c\/li\u003e\n\u003cli\u003e54\" Handle Assembly\u003c\/li\u003e\n\u003cli\u003eAir Hose Kit\u003c\/li\u003e\n\u003cli\u003eWheel Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e\n\u003csection id=\"installation-setup\"\u003e\n\u003ch2\u003eInstallation \u0026amp; Setup\u003c\/h2\u003e\n\u003cp\u003eYou'll need a compressed air supply capable of delivering between 116 and 174 PSI.
