Regular price $ 699.00 Sale price $ 649.00


This complete dual battery kit is designed to fit ALL Toyota Tacoma's from 2005 - Current and allow installation of two Group 35 AGM batteries side-by-side in the factory battery location.

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


Kit Includes:

  • OGE Exclusive "Side-By-Side" battery tray. Cut from 1/4" 5052 Aluminum.  
  • CNC machined aluminum dual battery tiedown with removable relay 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 and high amp draw scenarios.  The ACR is marine grade, made in the USA, and has a lifetime warranty!
  • *NO LONGER INCLUDED*  In-Cab Management Switch with exclusive OGE plug-and-play wiring harness.  The Blue Sea 2146 Contura Switch paired with custom OGE wiring harness allows for remote control operation and monitoring of your ML-ACR.  Manually link or isolate your auxiliary battery from your drivers seat!  The built-in LED's alert you to over-charge/ under-charge conditions as well as the current state of the relay (linked/ unlinked). **This is the only piece of our kit that was manufactured overseas.  Due to the current world situation, supply chain shortages and shipping delays, we no longer offer this wiring harness as a piece of the kit** Your ACR will be prewired for automatic function but it will retain it's manual override feature.
  • 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.
  • 4 pure lead Mil-Spec terminals

*Recommended batteries for use in this system are the Full Throttle FT750-35 or any other high quality Group 35 AGM battery

*Installation requires cutting and crimping of the factory cables, as well as drilling 7 holes in the factory battery mount.  You will need access to a heavy duty cable crimper to complete this installation*
