Here is the COMPLETE DUAL BATTERY SOLUTION for your 2005+ Toyota Tacoma

This system comes with everything (minus batteries) you will need for a fully functional dual battery system.

This system utilizes the abundance of space where the factory battery sits and allows for the installation of two Group 35 batteries side-by-side. See below for battery recommendation.


Kit Includes:

  • OGE Exclusive "Side-By-Side" battery tray with tiedown. Cut from 1/4" 5052 Aluminum.  
  • Beautifully-machined OGE aluminum tiedown with removable ACR plate
  • Blue Sea 7622 ML-ACR 500 amp, dual voltage sensing relay. The Blue Sea ML-ACR is the most robust smart relay on the market.  It is dual voltage sensing and completely automatic.  It does all the battery linking/ unlinking for you, but also features manual override for self jumpstarting, etc.  The ACR is marine grade, made in the USA, and has a lifetime warranty!
  • ALL necessary cables, including extensions with butt connectors for factory starter and ground cables. All cables are pre-terminated with tinned copper lugs that are properly crimped. The cables are then covered in abrasion resistant braided wrap and finished with 3M adhesive lined heat shrink. All the hard work is done!
  • 4 Mil-Spec terminals
  • Plenty of high quality zip-ties.


The recommended batteries for this tray are the Optima D35 Yellow Top for a lightweight setup, or any other quality Group 35 battery such as the Odyssey PC1400, X2 Power, Northstar, or Deka.

**This kit does require cutting and crimping of your factory cables, as well as drilling 7 holes in the factory battery mount.  You will need access to a heavy duty battery crimper to complete this installation**
