This stainless steel battery box was designed for heavy use off-road on vehicles like the 4Runner, Tundra, Tacoma, and many other trucks & SUVs.

Awesome product, excellent customer follow up.

Russell Brands (New York, NY)
Great box! Battery is stuck solid as a stepsister in a dryer!

Really though! I had the stock bracket on as good as it could be. It was fine, but I can shake the whole truck with this thing & it doesn’t budge. Worth it!

Thanks Russell!
We truly appreciate the feedback!!

Abel Diaz Jr (Miramar, FL)

I thought it was a little pricey until I received it and was able to appreciate the quality of the material and workmanship.

Hey there Abel!

Great piece! Quick shipping, cnc/water jet cutout is top notch. Can’t wait to install it, will add pic as soon as that happens. Cheers!

Hey Eddie,

Thanks for the awesome feedback!! Glad you're loving it

Miller Power Systems Inc (Arroyo Grande, CA)
Great quality product!

My only gripe would be that it doesn't just come with a set of j hooks.. it's just always nicer when you aren't required to get extra parts at the store to be able to install what just showed up to my house. My 2020 has the welded in j hook on one side so I ended up cutting the weld and reusing. Sexy CNC work however!
