DUAL BATTERY KIT

The 2010-2014 FJ Cruiser has pretty limited space in the engine bay, making it more difficult than previous years to fit add-ons like a second battery, auxiliary relay module, compressor etc.

One advantage of the 2010-2014 FJ however, is that it has a reinforced mounting point on the passenger side front of the vehicle. This location is a mirror image of the driver side, which holds the stock battery. This is desirable for a second battery because the body has been reinforced in this area and has considerably more structure than the thin wheel well sheet metal found near the firewall in the common second battery location.

The stainless tray bolts to the body in the second battery location, pushing the battery forward and out of the way of the air box. It includes integral mounting brackets to relocate the power steering reservoir and AC line that sit on the mounting plane, pushing then slightly further into the engine bay.

For 2010-2012 FJ’s, this kit is all you need to add a second battery! The washer fluid reservoir kit and smog pump relocation kit are not required to complete installation of the dual battery tray on these model years. 2013+ FJ's and 4Runner's will need to relocate the secondary air injection pump. A kit that works in conjunction with our washer fluid reservoir relocation system to move the pump to the rear passenger location is available and will be discussed later.
