I've wanted a side-by-side battery tray for years, but...

Been waiting to see if this will ever come back in stock but it appears not. Sadly, I have a manual transmission Sport model with a brake pressure slinky thingy so there is no room on the passenger firewall side for a tray. Yes, others have said I can move the airbox, and still others have done something up near the radiator on the passenger side, but I don't want to move factory stuff.

The only negative might be the discussion of how thin the radiator mount aluminum is and when 4-wheeling it can shear due to the weight of two batteries, but I'm using a lighter standard battery not the Lithium or red/yellow/blue AGM ones so s/b fine.

Any ideas of where there might be one sitting forgotten on a shelf?

 

This is your best bet for a second battery

as you eluded the weight of a second battery up front will destroy your core wall bushings and crack / split the core wall itself not the radiator

 

DUDE! That's looking perfect! Thank you for this! Going to do some research and contact them, wondering if the composite bed material can withstand the bouncing without shearing at the mount points. Is this something you've done by chance?

I have had a Redarc BCDC 1250 sitting in its box for years now, just waiting until I get my house battery figured out...yay!
