    Probably best dual battery tray for RHD JK

    Posted by Moha on 26th Mar 2018

    Solid product. Comes with pictorial instructions and can be fitted on a Saturday afternoon with usual tools (plus small angle grinder or better a rotary tool). However, it's only suitable for Optima batteries due to the height limit. It would be great if it was a bit lower (~2CM) to fit standard height batteries too. Also, it would be awesome if it had side holes or brackets for the christmas tree cable holders removed from the factory tray. I used zip ties to hold the cables together between the engine and tray because I don't like the thought of loose cables although they looked tight enough. I would definitely recommend.

    Simple to install with some basic hand tools and cutting tools. Instructions were fantastic and the fit is perfect. The quality and finish of the product is exceptional.

    Dual Battery System for JK Wrangler 3.6L Pentastar

    Posted by Tony Ogle on 11th Nov 2015

    Exactly what I wanted and even better is that it is in the engine bay and not in the rear cargo area.

    Excellent product

    Posted by Matt on 16th Jun 2015

    Easy to install and follow instructions took about 2 hours. Solid construction. For my setup a slightly deeper box would have been preferable, but still a great product.

    Seriously worth it

    Fits beautifully under the bonnet and so much better than having the battery taking up much needed room in the cargo area. Got an auto electrician to fit it (I'm too lazy) with no hassles at all.

    Excellent Addition to your JK Pentastar

    Posted by Steve on 30th Dec 2014

    Highly recommended for an easy DYI fit out. Completed within a few hours using an easy to follow set of pictorial instructions and basic tools. Better option than a battery in the cargo area.
