Question:

What’s the difference between the Dexter 4.4K and 3.5K ABS brake assemblies? They both look like 10-inch brakes.

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 vs 3 inch for 4400lbs) or reading the bearing numbers will confirm it.

Thanks, Andrew. That clears it up. My trailer is a 2022 Jayco Eagle HT and the axle tag says 4,400 lbs, but I just wanted to make sure since both brakes looked almost identical online. I’ll double-check my bearings before ordering.

@Allen That’s a great plan, Allen; those 10" Dexter ABS assemblies can fool you at a glance since the housings look so similar. With your Jayco’s 4.4K axles, the # DX83WR will be the perfect fit. Just make sure the bearings match up (inner L68149, outer LM67048) and you’ll be all set.
