Built for boat trailers, where the axle spends its life being dunked in water.\u003c\/p\u003e\n\n\u003ch3\u003eBefore you order - two things that catch people out\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThere are no spring holes.\u003c\/strong\u003e This axle ships undrilled. You will need to drill 9\/16\" holes to match your spring centers, or use adjustable spring mounts. This is normal for a replacement axle - it lets one part fit many trailers - but it means the job needs either a drill press and careful measurement or a set of weld-on adjustable mounts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMeasure your hub face, not your old axle's total length.\u003c\/strong\u003e Hub face is the distance between the outer faces of the two hubs, and it is the measurement that determines whether your wheels end up in the right place. This axle is 87-1\/4\" hub face with 71.75\" spring centers. If your spring centers differ, adjustable mounts solve it; if your hub face differs, this is not your axle.\u003c\/p\u003e\n\n\u003ch3\u003eWhy galvanized matters on a boat trailer\u003c\/h3\u003e\n\u003cp\u003eA boat trailer axle is submerged every time you launch, then driven down a salted road in the off season. Painted axles fail from the inside out where you cannot see it. Galvanizing puts a sacrificial zinc layer over the whole tube, and the stainless steel wear sleeve on each spindle protects the sealing surface the grease seal rides on - the spot where a corroded axle usually starts leaking and eats its bearings.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e3,500 lb capacity\u003c\/li\u003e\n\u003cli\u003e2\" x 2\" square tube, galvanized finish\u003c\/li\u003e\n\u003cli\u003eBrake flange welded at each spindle\u003c\/li\u003e\n\u003cli\u003eStraight spindle, 5-lug hub pattern\u003c\/li\u003e\n\u003cli\u003eStainless steel wear sleeve on spindles\u003c\/li\u003e\n\u003cli\u003e1.0° camber per side, welded at the spindles\u003c\/li\u003e\n\u003cli\u003e87-1\/4\" hub face, 71.75\" spring centers\u003c\/li\u003e\n\u003cli\u003eBearing sizes 1-3\/8\" and 1-1\/16\"\u003c\/li\u003e\n\u003cli\u003eNo spring holes - drilling or adjustable mounts required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat is included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAxle with welded brake flanges and straight spindles\u003c\/li\u003e\n\u003cli\u003eWashers\u003c\/li\u003e\n\u003cli\u003eCastle nuts\u003c\/li\u003e\n\u003cli\u003eCotter pins\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHubs, bearings, seals and brake assemblies are \u003cstrong\u003enot\u003c\/strong\u003e included and are ordered separately to match your setup.\u003c\/p\u003e\n\n\u003ch3\u003eShipping\u003c\/h3\u003e\n\u003cp\u003eThis axle is 92 inches long and weighs 70 lb, so it ships by freight rather than parcel.

You either measure and drill 9\/16\" holes to match your spring centers, or fit adjustable spring mounts that clamp to the tube and let you set the position. Adjustable mounts are the safer route if your measurements are uncertain.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I measure my existing axle?\u003c\/strong\u003e\u003cbr\u003eMeasure hub face to hub face - the outer face of one hub to the outer face of the other. Then measure spring center to spring center. Those two numbers identify the axle. Overall tube length alone will not.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does it have camber?\u003c\/strong\u003e\u003cbr\u003eThe 1.0° camber per side is built in so the spindles run level once the axle is loaded to capacity. An unloaded axle will look slightly bowed - that is correct.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need brakes on a 3,500 lb axle?\u003c\/strong\u003e\u003cbr\u003eThat depends on your state's trailer brake requirements and your loaded weight.
