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

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!

Battery box for my new battery

FJC Battery Box High Quality

This is a really high quality battery box. The stainless steel and the weldings are amazing. I wish they would put the internal WxLxH on the website for not looking into a reference value over odyssey’s web page and doubting between which sizes to choose. Only thing about the product itself is your battery might not fit perfectly, but do not worry, nothing a 3D printed TPU can’t easily fix. It is easy to install and looks great. On the images you can see both spacers. Great product, only thing I would like are the measurements.
