Features to know about

Solid Mounting for Heavy Loads: Built for 10,000- to 15,000-lb Dexter Axles

When you’re running a heavy-duty setup, you need hangers that can take the weight without flexing. This kit is made for single-axle use with 10,000-lb to 15,000-lb Dexter axles. The front hangers stand 6-1/4" tall with 1" bolt holes, while the rear hangers measure 7-11/16" tall with 1/2" bolt holes. That solid steel hardware gives your suspension the strong base it needs to track straight and hold steady under load.

Straightforward Setup: Complete Hardware for Proper Frame Mounting

A secure suspension starts with the right parts that fit together cleanly. This kit includes the front and rear hangers plus all the hardware for mounting your springs to the trailer frame—spring keeper bolts, spring-eye bolts, and matching locknuts in correct sizes. Everything lines up so you can attach two leaf springs (sold separately) and have a dependable mount right out of the box.

Designed to Match Dexter Components: Works with HAP-203-01, HAP-203-02, or HAP-203-03

If you plan to expand or build out a tandem setup later, this single-axle kit is ready for it. It’s made to pair with Dexter’s HAP-203-01, HAP-203-02, or HAP-203-03 kits for multi-axle use. The geometry and bolt sizing stay consistent across all of them, so your suspension parts stay aligned and perform as one system.

Reliable Fit for 3" Slipper Springs: Simple and Durable Connection

This hanger kit is built specifically for 3" wide slipper springs. That makes it easy to line everything up during installation and ensures a snug, durable fit once bolted down. The design keeps the spring movement controlled while letting it flex naturally over bumps for a steady ride on any job or trip.

See what our Experts say about this Dexter Trailer Suspension Parts

  • What Parts Do I Need to Add a 3-Inch Lift on My 2016 Airstream Flying Cloud Travel Trailer?
    I have a solution for you to raise your axles. Unfortunately, I could not find any specs of your axles on your 2016 Airstream Flying Cloud travel trailer. However, if you have double-eye leaf springs installed on your trailer, I recommend an over-under conversion kit like the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00 (for 3-inch axles) or # K71-384-00 (for 2-3/8 inch axles). In order to determine which kit you need, I recommend measuring the thickness of your axles....

  • Does 24-3/4" Dexter Equalizer Come with Center Hangers
    Yes, you can get the 24-3/4" Dexter Equalizer # 13-109-3 in a kit with the center hangers as part # HAP-203-03. If you're needing the front and rear hangers then the kit # HAP-103-00 will complete your hanger setup. Attached are some review videos for you to check out.

  • Direction Rear Hanger # 30-66-1 Should Face
    You are correct. The angle of the plate in the Rear Hanger # HAP-103-00 you referenced faces forward and the bolt hole points towards the rear of the trailer.

  • Spring Hangers for 3" Slipper Springs
    The Dexter Single-Axle Trailer Hanger Kit for 3" Slipper Springs # HAP-103-00 is what we have for a single axle that uses the 3" wide spring hangers. We also have kits for Tandem or Triple axle applications if you are needing those. If this is not what you are wanting please let me know and I will do my best to find you exactly what you need.
