Made in the U.S.A Bolt-in battery tray (powder coated standard) with over the battery, hold down strap Two 5/16″ bolts, two washers, and two clip-on barrel nuts **Maximum battery size of 10-1/2″x 8″x 7″ tall*** Is the battery in your ZJ held in by a bungee cord? Maybe some string? Maybe hope? Well, that’s relatively typical because the factory plastic battery trays are easy to break and seem broken often. Enter the MVF 100% American steel replacement! This new battery tray bolts into the stock location with no modifications required. The battery sensor is still retained at the bottom of the new tray. Using the new hold-down included and two new bolts, you can secure your battery safely and never worry again. This will allow you to mount most batteries, not just Optimas. The new tray is powder-coated with an intense poly-based texture black.
