Features to know about

Built for Heavy Loads: Complete Hanger Kit for 10,000-lb Tandem Axles

When you’re hauling serious weight, you need suspension parts that can take it. This hanger kit is designed for tandem, 10,000-lb general-duty Dexter axles and uses solid steel hangers in three sizes—5-1/4" front, 4-1/2" center, and 4-1/2" rear—to keep everything aligned and stable. It attaches four 2-1/2" wide slipper springs (sold separately) to your trailer frame for a strong, balanced setup that handles heavy loads without flexing.

Smooth, Even Ride: 18-3/8" Equalizers Maintain Proper Axle Spacing

Uneven axle spacing can make a trailer bounce or sway. The 18-3/8" long straight equalizers in this kit keep the 42-1/4" spacing between axles consistent so the load is shared evenly. Each equalizer has a 1" diameter center hole for mounting to the hanger and a 3/4" side hole for the spring connection, giving the suspension just the right amount of flex to keep the ride steady.

Strong Connection Points: Matched Hardware for Secure Suspension

The kit includes all the core hardware for the hangers and equalizers—(4) 4-1/2" long x 3/4" diameter spring-eye bolts with matching locknuts, and (2) 5-1/4" long x 1" diameter equalizer bolts with their locknuts. Each piece fits precisely with the hangers and equalizers, locking the suspension together so it stays tight mile after mile.

Easy Alignment for Reliable Tracking: Dialed-In Geometry

Getting the geometry right matters for straight tracking on the road. The hanger spacing—35-1/10" between front and center hangers, 34-2/3" between center and rear, and 5" from axle center to frame—is set up for proper axle placement. Once it’s installed, the suspension sits square and level, keeping your trailer stable and predictable whether loaded or empty.

  • Determining Proper Axle Spacing
    There is not a recommended space between axles to achieve a higher load capacity. The best position for your axles is going to depend on the factors outlined in the attached diagram. Those weights and measurements are really going to be the deciding factor on what hanger kit you want; the Dexter Tandem-Axle Trailer Hanger Kit # HAP-158-258-02 for 42" spacing or kit # HAP-158-258-03 for 48" spacing.

  • Installation Kit for UG54FR Trailer Slipper Spring on a Tandem Axle Trailer
    The 5-Leaf Slipper Spring w/ Radius End for 10,000-lb Trailer Axles - 30-1/2" Long # UG54FR, is a slipper style spring. Double eye springs would have an eye on each end of the spring. To build a double axle trailer with these springs you will need one of two tandem axle hanger kits, depending on the spacing you need between the axles for the wheel and tire combination you plan on using. The Tandem Axle Hanger Kit, # HAP-158-258-02, will give you 42-1/4 inches on center between the axles...

  • Tandem Axle Equalizer Kit for a Trailer with 10,000 Pound Axles
    Tandem axle trailer equalizer kit # HAP-258-01 isn't a 2-piece equalizer set. It has 2 equalizers and 2 hangers. The equalizers are 14-1/4 inches long though. If the recommended spring is longer than the old springs then the equalizer kit still may work for you. Otherwise we have kits with longer equalizers including # HAP-158-258-02 which has 18-3/8 inches long equalizers.
