Question:

2021 Dutchmen Voltage 3845 8000lb axles. Im looking for a wheel bearing kit. would like Timken but I dont see that you carry a full kit? Looking to replace them and rings, seals. Also 4 electric break assemblies. Thanks Roy

Hey Roy, while we don't have a Timken bearing kit we can piece together the correct components as we do have them individually. For the outer bearing you would want the part # TMK75FR, for the inner # TMK44FR.

For a seal part # 10-36 for a pair.

Then for a set of self adjusting brake assemblies for an 8k trailer axle you would want the part # 23-434-435. Do you know what brand of axles you have? These fit Dexter and Lippert which are the most common.

@RoyR Perfect! The brake assemblies I mentioned would be correct then. I just found a much better priced set too I should have mentioned too with the part # AKEBRK-8 as well. These are also self adjusting.

@JamesonC I have been very happy with the etrailer branded brake assemblies on my 21k gooseneck trailer, especially with the price point vs the dexter assemblies.
