Product Description

Jeep was nice enough to put a storage tub under the rear cargo area of a JK wrangler.  Problem is, it's tiny.  Uneek 4x4 have made an enlarged tub that replaces the factory one and greatly increases the storage capacity. Purpose built to clamp down an Optima D31A battery as well.


Perfect spot to fit a 2nd battery or just tools and recovery gear, especially for diesel owners.

Suits All JK Wranglers



Product Features


  • Constructed from 3mm steel
  • E-coated black for the best corrosion resistance available 
  • Comes with battery clamps and locators for Optima D31A batteries (same as what CRD JK diesel uses)
  • Fully sealed with electrial glands and bungs included to run cables outside of the vehicle if required.
  • Huge storage space fits where existing tub used to go
  • Suits all JK wranglers 2007-2014
Note: This product requires the rear muffler to be relocated, and the factory storage box to be cut out
Install difficulty 6/10
Install time 3 hours

    This enlarged tub is a great addition to my JK, followed the instructions and it went perfectly, couldn't fault it.
    I would strongly recommend going the nutserts route; they work amazingly well.
    Highly recommend this battery box!

    Works well. But I would use a hammer and dolly to reshape floor rather than cutting. Recommended this product..

    I purchased this storage tub for my Diesel JK because there was no place to install a second battery. Its fits an optima D31a perfectly and i went with a red arc bcdc charger which mounts nicely on the back wall and a Baintech 12v power board which i have unmounted on the right side of the tub for flexibility. The entire product and finish are really durable and the mounting hardware is good quality. Took about 3 hours to install. I had to grind the underside mounting brackets because they were a little to long. Other than that, everything fits well. Highly recommend.

    The battery box is the perfect addition to enable a steeds dual battery system without having to loose any storage area within your cab. It's easy to install and when the job is completed it looks like a factory item.
    I highly rate it :)

    Thanks Uneek 4X4

    Great box... Strong and well made.. Fairly simple to instal if you take your time.. The instructions are sufficient and easy to read... Only one area where they could be a little better re the point of measure for the first mark/cut..
    Two people make the instal much easier re the nuts/bolts... Nutserts (supplied) would be easy too if you have a Nutsert tool...
    On mine the bolt holes for the battery bracket needed a little love to make them comply...
    A full size AGM battery and an ARB twin compressor fits inside snugly.
