The AFF 546SD from American Forge and Foundry is a two-stage air hydraulic axle jack rated at 25 tons on the first stage and 10 tons on the second, made for the daily punishment of heavy-duty trucking, agricultural, and fleet maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThe two-stage design gives you real flexibility on the job. The 25-ton first stage has the muscle to move a loaded tandem axle without hesitation. When you need more lift height at a lower load, the second stage extends the ram further - and with the extensions included in the box, you can push the working height to nearly 21 inches without hunting down adapter parts. Everything ships with the jack.\u003c\/p\u003e\n\u003cp\u003eWhat separates this from a generic air hydraulic axle jack is how it holds a load. The piston head seal design comes straight from industrial hydraulic technology, which means a better grip under severe weight and far less drift over time. Double-polished chrome pistons maintain tighter tolerances, cutting down oil bypass and the ram scoring that kills cheaper units. Integral descent metering keeps your lowering controlled - no sudden drops when you're working under a loaded axle. A built-in overload safety valve protects the unit if someone miscalculates the capacity.\u003c\/p\u003e\n\u003cp\u003eThe 54-inch handle locks into three positions so you can work around frame rails, axle housings, and tight undercarriage obstacles without repositioning the entire jack. It's been tested down to -13°F and up to +113°F, plus off-center loading, so it performs in real conditions - not just ideal ones. Free shipping to the lower 48 and direct phone support before and after your order mean you're covered from purchase to lift. If you're comparing this to the 547SD or sizing up against a 30 ton air hydraulic jack for a heavier application, call us and we'll help you pick the right tool.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection id=\"specifications\"\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003eValues listed as Stage 1 (25 ton) \/ Stage 2 (10 ton) where the two stages differ.\u003c\/p\u003e\n\u003ctable class=\"gsg-spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacity\u003c\/td\u003e\n\u003ctd\u003e25 Tons \/ 10 Tons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRam Lift\u003c\/td\u003e\n\u003ctd\u003e3.82\" (Stage 1) \/ 7.56\" (Stage 2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow Height\u003c\/td\u003e\n\u003ctd\u003e7.28\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHigh Height\u003c\/td\u003e\n\u003ctd\u003e11.10\" (Stage 1) \/ 14.84\" (Stage 2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHigh Height with Extensions\u003c\/td\u003e\n\u003ctd\u003e16.85\" (Stage 1) \/ 20.59\" (Stage 2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking Air Pressure\u003c\/td\u003e\n\u003ctd\u003e116 - 174 psi\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\u003eShip Weight\u003c\/td\u003e\n\u003ctd\u003e128 lbs.\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 546SD Air\/Hydraulic Axle Jack\u003c\/li\u003e\n\u003cli\u003e75mm (3\") Extension\u003c\/li\u003e\n\u003cli\u003e45mm (1.75\") Extension\u003c\/li\u003e\n\u003cli\u003eSaddle Adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e\n\u003csection id=\"installation\"\u003e\n\u003ch2\u003eInstallation \u0026amp; Setup\u003c\/h2\u003e\n\u003ch3\u003eAir Supply Requirements\u003c\/h3\u003e\n\u003cp\u003eThe AFF 546SD is an air operated hydraulic axle jack - it needs a shop air connection to run. Your supply line needs to deliver between 116 and 174 psi at the jack inlet. Most shop compressors operate comfortably in that range. Verify your fittings and hose are rated for your working pressure before connecting. Air is used both for powered lifting and for air-assisted ram retraction on the way down.\u003c\/p\u003e\n\u003ch3\u003ePositioning and Handle Setup\u003c\/h3\u003e\n\u003cp\u003eSet your handle position before rolling the jack under the vehicle. Three lock positions let you approach from whatever angle works around frame crossmembers, fuel tanks, or undercarriage obstacles. The low height on both stages is 7.28\" - that's the minimum clearance you need between ground and lift point to get the jack positioned. Measure before you commit.\u003c\/p\u003e\n\u003ch3\u003eExtensions and Saddle Adapter\u003c\/h3\u003e\n\u003cp\u003eThread one or both extensions onto the ram before you start lifting if extra height is needed. The saddle adapter gives you a stable contact surface on round or irregular axle housings. Stacking both extensions on Stage 2 brings your maximum working height to 20.59\". Don't stack extensions after the load is on the jack - set your configuration before lifting.\u003c\/p\u003e\n\u003ch3\u003eCalifornia Proposition 65 Notice\u003c\/h3\u003e\n\u003cp\u003eCalifornia residents: this product is subject to Proposition 65 warning requirements.
