Features to know about

Built for ABS Tow Assist Safety

When traffic suddenly slows and every second counts, Dexter's ABS Tow Assist brakes step in. Each assembly has a built-in ABS sensor that talks directly with your Tow Assist system, helping prevent wheel lockup and keeping your trailer stable under hard braking. The same system also applies selective braking to help reduce trailer sway, giving you more confidence and control during highway cruising and in emergency stops.

No Manual Adjustments, Ever

Traditional brakes need regular tweaking as the shoes wear down. With Dexter's Nev-R-Adjust system, these assemblies take care of themselves. A tensioning cable inside keeps the shoes aligned for peak stopping power mile after mile, so you spend less time wrenching and more time towing.

Straightforward Electric Setup

No actuators, no hydraulic lines, just connect to your in-cab brake controller and reinitialize your Dexter Tow Assist system after installation. Once reset, the integrated ABS sensors sync automatically, giving you reliable braking performance with minimal upkeep.

  • 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.

  • 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...

  • What's The Difference Between 3.5K And 4.4K Dexter Axle With ABS Tow Assist Brakes?
    Jim, they’re both 10 inch x 2-1/4 inch brakes, but the 4.4K # DX83WR uses a different outer bearing LM67048 and different flange pattern than the 3.5K # DX73WR, which uses L44649. The plate offset and magnet alignment differ, so they aren’t interchangeable. Also, the magnets are different so they'll brake at different strengths. Definitely don't try to swap these. If your axle tube measures 2-3/8", that's likely 3.5K; if it’s 3", you’ve likely got a 4.4K axle. You can also look for axle...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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?

  • 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!
