Features to know about

Stops Straight and Stays in Control: ABS Tow Assist Keeps Braking Smooth

Hard stops or wet roads can make a trailer want to push or sway, but these Dexter 10" electric brakes with integrated ABS Tow Assist sensors help keep things steady. Each assembly communicates directly with the Tow Assist system to prevent wheel lockup and apply selective braking when needed, so you stay in control even during sudden slowdowns or uneven traction. Built for 3,500-lb ABS axles with a 4-bolt mounting flange, they give you reliable, balanced stopping power every time you hit the brakes.

No More Manual Adjustments: Nev-R-Adjust System Handles It Automatically

Crawling under a trailer to tweak brake shoes gets old fast. These Dexter Nev-R-Adjust assemblies take care of that job for you. A tensioning cable inside automatically maintains the correct shoe clearance as the brakes wear, keeping pedal feel consistent and stopping power strong without any manual adjustments. Once burnished in with 20–30 smooth stops, they’ll keep themselves dialed in for the long haul.

Simple Electric Setup: Plug-In Fit for Easy Replacement

Swapping out worn brakes doesn’t have to be complicated. The Dexter ABS 3.5K assemblies mount to a standard 4-bolt flange and connect directly to your existing brake wiring and sensor plugs—no hydraulic lines or reprogramming needed. Once torqued to spec and powered up, the Tow Assist module recognizes them automatically and shows a solid green indicator so you know everything’s synced and ready to roll.

Built for Long-Term Dependability: Proven Dexter Design

These 10" x 2-1/4" drum brakes use bonded shoes and a durable magnet design that holds up through miles of towing. Compatible with 13", 14", and 15" wheels, they deliver the steady braking performance you expect from Dexter. With a limited 5-year warranty backing them up, they’re made for dependable use trip after trip.

See what our Experts say about this Dexter Trailer Brakes

  • What Is The Difference Between Dexter ABS 4400lbs And 3500lbs Brake Assemblies? Both Are 10"
    Good catch, Allen - both the 3.5K # DX73WR and 4.4K # DX83WR use 10 inch x 2-1/4 inch shoes, but the 4.4K version is built for a heavier spindle and a different bearing combo. The 4.4K uses L68149 inner and LM67048 outer bearings, while the 3.5K uses L68149 and L44649. The backing plates are different bolt patterns and the sensors are tuned for those axle specs, so they’re not interchangeable. If you’re unsure which axle you’ve got, measuring your tube diameter (2-3/8 inch for 3,500lbs...

  • Replacement Brakes for Dexter ABS Tow Assist on Trailer With 3,500 lb Axles
    Hey Don! We do have the replacement brakes for the Dexter ABS system. What you need is the Dexter Electric Trailer Brake for Dexter ABS Tow Assist - 10" - Left/Right Hand - 3.5K # DX73WR. How has that brake system been working for you? I've heard good things.

  • Do I Have To Adjust New Dexter ABS Brakes After Installing On Trailer?
    Nope - that’s one of the perks of these. All models of Dexter ABS Brake Assemblies, such as 3.5k # DX73WR, 4.4k # DX83WR, 7.5k # DX23WR, and 8k # DX55WR, are Nev-R-Adjust brakes. They’ll automatically maintain the proper shoe clearance once they’re burnished in. Just make sure to follow Dexter’s break-in procedure - about 20–30 controlled stops from 40 mph - so the shoes seat evenly. Brian, are you replacing a single axle or doing all four corners? It’s best to do them all at the same...

  • Are Dexter ABS Brakes For 3,500lb Axles The Same Fitment As 4,00lbs Axles?
    Good eye, Brian - both the 3.5K # DX73WR and 4.4K # DX83WR Tow Assist brakes are 10 inch x 2-1/4 inch, but they’re not interchangeable. The 3.5K version uses different mounting offsets and lighter components for smaller spindles, while the 4.4K version fits a heavier hub and uses a slightly different bearings. If one axle tag shows 3,500 and the other 4,400, replace each axle with the matching rated assembly so the ABS sensors read correctly. Are you planning to replace all four at once,...

  • Direct Bolt-on Replacement Brakes For 2024 Jayco Eagle HT With Dexter Tow Assist anti lock brakes
    Hey Andy! Great name by the way. Yes, the Jayco Eagle HT models with 3,500-lb Dexter Tow Assist axles use the 10 inch # DX73WR assemblies. They bolt up to the standard 4-bolt flange and plug straight into your trailer’s brake and ABS harnesses. If your axle tubes measure about 2-3/8 inch in diameter, that confirms the 3.5K size just in case you weren't completely sure. Are you planning to do both axles at once? That’s usually the best route for even braking. Other Jayco owners - how’s...

  • Can I Use Time-Delayed Brake Controller With Dexter ABS Brake System, Or Just Proportional?
    Jeff, technically a timed controller will work, but Dexter strongly recommends an inertia-based proportional brake controller for the Tow Assist system. Timed controllers can trigger the ABS more often than needed because they apply power on a preset ramp instead of responding to your vehicle’s actual deceleration. Proportional units like the Tekonsha Prodigy P3 or Redarc Tow-Pro Elite are both verified compatible. What controller are you using now? I can let you know whether it’s on Dexter’s...

  • Do Dexter ABS Brakes Have Smoother Braking Than Standard Electric Brakes On RVs?
    Good question, Shelby. Under normal braking, the Dexter 3.5K ABS Tow Assist brakes # DX73WR will feel the same as standard electric brakes. The Tow Assist system only steps in when it detects wheel slip or sway, adjusting brake force momentarily to help the trailer stay straight and stable. Otherwise, they operate like any other electric drum brake. Are you replacing the brakes on an existing Tow Assist trailer, or just trying to confirm what’s already installed? Anyone else here notice...

  • Replacement Electric Brakes For 3,500lb Axle On Travel Trailer With OEM Dexter ABS System
    Matt, the Dexter 10 inch ABS Tow Assist brakes # DX73WR are exactly what you’ll need if you indeed have a 3,500-lb axle with the ABS hub setup. They bolt to the standard 4-bolt flange and connect to your existing sensor and plugs. If your axle tube measures 2-3/8 inch in diameter or your bearings read L68149 inner and L44649 outer, that confirms it’s the 3.5K size. What type of trailer do you have? I've heard of these brakes being added on quite a few higher end travel trailers from the...

  • Do 10" Dexter ABS Brakes Need Adjusted After Installation Like Old Trailer Brakes Do?
    No manual adjustment needed, Chad - both the 3.5K # DX73WR and 4.4K # DX83WR assemblies feature Dexter’s Nev-R-Adjust design. Once installed and burnished in, the internal tensioning cable automatically maintains the proper shoe clearance. You’ll still want to follow Dexter’s initial break-in procedure 20–30 gradual stops so the shoes seat evenly with your drums. Do you know which brake assemblies you need? If not, let me know and I can walk you through it!

  • Do I Need To Reset Anything After Replacing Brakes On Dual Axle Trailer With Dexter ABS Tow Assist?
    No reset needed, Dustin. The Dexter 3.5K ABS brakes # DX73WR plug in and are automatically recognized by the Tow Assist module. Just torque to spec, reattach both brake and sensor plugs, and when you power up, the indicator should show solid green. Are you doing the install yourself or through a shop?
