Features to know about

Steady Ride for Heavy Loads: Designed for 10,000-lb Tandem Axles

When your trailer carries serious weight, you need suspension parts built to match. This hanger kit is made for tandem, 10,000-lb, general-duty Dexter axles and keeps everything aligned with 48-1/2" axle spacing. With 5-1/4" tall front hangers, 4-1/2" tall center and rear hangers, and 24-5/8" long equalizers, it gives your 2-1/2" slipper springs the solid support they need for smooth suspension travel.

Precise Geometry That Tracks True: 48-1/2" Axle Spacing Made Simple

Getting the spacing right between axles makes all the difference in how your trailer rides. This kit locks in 48-1/2" between axles, with 38-1/3" between front and center hangers and 37-7/10" between center and rear hangers. The layout keeps axle alignment consistent and ensures even weight distribution, so your suspension works the way it’s supposed to mile after mile.

Built Strong from the Ground Up: Heavy-Duty Steel Hangers and Equalizers

Each hanger and equalizer is made to handle high-load use. The equalizers are 24-5/8" long with a 1" diameter center hole and 3/4" side holes for secure bolt attachment. The front hangers use 3/4" bolt holes, center hangers use 1" bolt holes, and all mounting hardware is included—spring-eye bolts, equalizer bolts, and locknuts—so each connection point stays tight and true under load.

Reliable Suspension Setup for 2-1/2" Slipper Springs

This kit attaches four leaf springs (sold separately) to your trailer frame and gives you a complete hanger layout ready to bolt in. The combination of 5-1/4" and 4-1/2" tall hangers keeps the ride height balanced while the long equalizers absorb road shock. The design works great for restoring a worn suspension or setting up a new build that demands dependable, heavy-duty performance.

  • How to Determine if Dexter Tandem-Axle Trailer Hanger Kit for 2-1/2 Slipper Springs Will Work
    I can tell you how to determine that, but there isn't a specific fit for any trailer, including your Big Tex, for the Dexter Tandem-Axle Trailer Hanger Kit for 2-1/2" Slipper Springs # HAP-158-258-03. Since you have 10,000 lb Dexter axles, you're set there, and you likely have 2-1/2 inch slipper springs (though you may want to measure their width just to be sure), so all you have to do is measure you axle spacing. To do this, simply measure from the center of one axle to the center of...

  • 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.

  • Hanger Kit For Tandem Axle Trailer With 2-1/2 Inch Slipper Springs & 10,000 lb Axles
    There are a few different hanger kits for a trailer with tandem 10,000 lb general-duty Dexter axles, depending on the axle spacing you have. - 38" Axle Spacing: Dexter Tandem-Axle Trailer Hanger Kit for 2-1/2" Slipper Springs # HAP-158-258-01 - 42-1/4" Axle Spacing: Dexter Tandem-Axle Trailer Hanger Kit for 2-1/2" Slipper Springs # HAP-158-258-02 - 48-1/2" Axle Spacing: Dexter Tandem-Axle Trailer Hanger Kit for 2-1/2" Slipper Springs # HAP-158-258-03

  • Axle Placement and Suspension System for 20,000 lb Bumper Pull Trailer
    For your trailer, the axle placement will dictate the hanger placement as will whether you use double eye springs or slipper springs. When positioning a trailer axle or adding an additional axle, the key is to make sure that the axles are located in just the right position so that roughly 10 to 15 percent of the total trailer weight is placed on the tongue. For a heavy duty trailer like you reference I recommend using the slipper spring # DX65QR along with the Dexter Tandem-Axle Trailer...

  • Tandem Axle Hanger Kit for 2-1/2 inch Wide Slipper Spring with 48-1/2 inch Axle Spacing
    Since you have a 2-1/2 inch wide slipper spring setup and the axle spacing is 48-1/2 inches the easiest solution for a tandem axle hanger kit would be the part # HAP-158-258-03 which matches all of that perfectly. This does use a different equalizer than what you mentioned but would work great still.

  • 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...

  • Replacement Equalizer Suspension Kit For A 2012 Gatormade Flatbed Trailer
    The closest option we have to your dimensions is going to be the Dexter Tandem-Axle Trailer Hanger Kit for 2-1/2" Slipper Springs # HAP-158-258-03 that you were already looking, which comes with a 24-5/8" long equalizer. This would throw off your suspension so you'd have to change the length of your leaf springs a bit shorter to accommodate the increased size of the equalizer.
