Our SDHQ Built Dual Battery kit for the 2007-2021 Toyota Tundra is the most durable dual battery system on the market today. There is no need to piece different components to make your dual battery set up to work. We include all the parts you need for a clean direct from the factory quality install. This dual battery kit was 3D CAD designed, engineered and built in-house for our typical SDHQ Built quality, fit, and finish.

Benefits of running a dual battery system:
If you are someone who goes or is planning on going on 4x4 camping trips (overlanding), then you will need auxiliary power. A dual battery system is where two separate batteries are working in conjunction with each other. However, each battery has a different purpose. Running a second battery will ensure your Toyota Tundra has start-up power and that your fridge, lights, and other campsite accessories have constant power.
