Hey Randy! We don't have a single kit but I can help you put together the parts you need to add brakes. It sounds like you don't already have brakes, so you need to make sure you have a brake flange on the axle.
Without the brake flange you won't be able to install any kind of brakes on the trailer. Assuming this is a 3,500 lb axle it will look like # 4-35 with 2-7/8" spacing on center. If you don't have a brake flange you either need to add one at an axle shop or replace the axle.
Do you know the bolt pattern on your hubs? More than likely it is 5 on 4-1/2 so you can use the Trailer Hub and Drum Assembly # AKHD-545-35-K. This is designed for 3,500 lb axles with a #84 spindle (L68149 inner and L44649 outer bearings). You can pair these with the etrailer Electric Trailer Brakes # AKEBRK-35-SA.
The only thing left is the wiring. You can add a 7-way using the etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box # e99011. You will tie the existing lights into the junction box and then run # 10-1-1 back to your brake assemblies.
Where are you headed next with your boat once you get the brakes installed? Do you have a brake controller for your 2024 Tacoma?
