I currently have four different self-adjusting assemblies for your boat trailer with 10" x 2-1/4" electric drum brakes. You can choose from the following: -Terran Axle Electric Trailer Brakes #TX97ZJ (3,500 Axles) -etrailer Electric Trailer…
To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…
The etrailer.com Electric Trailer Brake Kit #AKEBRK-7-SA and the Dexter Nev-R-Adjust Electric Brake Kit # 23-464-465 referenced in your question are both self-adjusting assemblies that will work to replace the existing Dexter brakes on your 7,000…
It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…
Hi Calvin! All of the pre-greased hubs/drums, like the Terran Industries Trailer Hub and Drum Assembly - 3.5K Axles - 10" Diameter - 5 on 4-1/2 #TX68VJ, come with bearings made overseas and are all basically the same quality. At least that I…
In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.
Hey Scott! I recommend using the Hydrastar Marine Electric Over Hydraulic Actuator for Disc Brakes #HS381-8067. Hydrastar is a reliable, proven brand so it will serve you well. Then for brake lines you can use the Hydrastar Hydraulic Brake Line Kit -…
Hey Dale, both DeeMax and Hydrastar make really nice disc brake components. Either kit is going to work really well for your 2022 Grand Design Reflection 337RLS. If you want the best of the best and don't mind paying for the premium brand then go…
The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…
The Dexter Nev-R-Adjust electric trailer brakes can be manually adjusted. There are a couple teeth of the adjustment wheel that are exposed just under the lever that you referenced. I have attached a photo showing the teeth. You will likely need a…
Hi Eric! You are correct. The Kodiak Disc Brake Kit - 13" Rotor - 8 on 6-1/2 - Stainless Steel - 1/2" Bolts - 7,000 lbs #K2R712S would need an idler hub (like the Dexter Trailer Idler Hub Assembly - 5,200-lb, 6,000-lb and 7,000-lb Axles -…
The Demco Hydraulic Trailer Brake Actuator part #DM72VR should be a direct replacement for the Atwood 61101 Brake Actuator that you have now. This newest updated it rated at 7K instead of 6K. This is a bolt on option that mounts on 3" centers.…

Match your brakes by checking hub diameter and the brake flange: 4 bolts means 10 inch, 5 means 12 inch. Free backing lets you reverse without locking up, ideal with hydraulic surge setups and boat trailers. If you have a #84 spindle, that confirms a 3,500 lb axle and 10 inch assemblies.
Free-backing brakes let you back up without the brakes locking. They eliminate having to pin the actuator to reverse. Check whether your actuator has a reverse lockout; if it does not, free-backing is a smart pick. This is especially handy on boat trailers when backing down ramps.
Confirm mounting hardware; some assemblies include studs but no nuts. We've seen studs at 7/16-20 UNF while old hardware was 7/16-14 UNC, so match threads or reuse bolts if needed. Test-fit to ensure shoes don't rub the drum. Plan to bleed the system and verify your actuator is for drum brakes, not disc.
Measure your hub diameter or count the brake flange bolts: 4 bolts indicates 10 inch, 5 bolts indicates 12 inch. You can also measure the drum's depth and width to confirm fit. If you have a #84 spindle, that points to a 3,500 lb axle that uses 10 inch assemblies.
Yes, match them to your hub/drum, not the wheel. Wheel fit comes from the hub, so if you run 10 inch drums with 13 inch wheels, that's a common combo. Verify your lug pattern like 5 on 4.5 and confirm drum width (2-1/4 or 2-1/2 inch) by measuring the hub/drum.
