Parts Needed to Install Electric Drum Brakes on 2018 Spartan Cargo 6 x 12 3.5K Single Axle Trailer


I have a 2018 Spartan Cargo S6x12 single 3500# axle trailer I would like to add electric drum brakes with parking brake feature. Mfr. said they use Lippert axels so Im wondering if these Dexters will fit the bolt pattern on the axel plate?

In the recent past axles have become more standardized so yes, the Dexter Electric Trailer Brake Assembly # K23-086-00 for left and # K23-087-00 for right should fit just fine as long as your current axles have a brake mounting flange with a 4 bolt pattern like part # 4-35.

You should also be able to use the hub and drum assembly # AKHD-545-35-K for a standard spindle or # AKHD-545-35-EZ-K for an EZ Lube spindle. Both of these use the inner bearing # L68149, outer bearing # L44649, and a grease seal that has an inner diameter of 1.179". If your bearings and seal have these parts and measurements there either of these assemblies will work just fine with your spindle.

To add wiring to your trailer I recommend installing the etrailer # e99011 which has a junction box to make installation easier. You then just need 10 Gauge Wiring # 10-1-1 and some Butt Connectors # DW05745-10 to complete the installation.

A breakaway kit like the Hopkins Engager Push-To-Test Trailer Breakaway Kit # 20099 is required by law so that in the even that your trailer becomes uncoupled the brakes will be engaged to avoid further damage.

The last thing that you need for the setup to be complete is a brake controller in your tow vehicle. If you don't already have one I highly recommend the Prodigy P3 # 90195. Let me know the year/make/model of your vehicle and I can let you know how to install the brake controller.

Attached are some review videos and a helpful article for you to reference.
