Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Rugged, Fortified JB4 Protection

Our most protective case in the JB4 line-up. The sleek, stylish JB4 billet aluminum enclosure withstands drops, shocks and bumps while protecting electronics from dirt and water. CNC machined with a rubber sealing ring. Ideal for all-weather F and G chassis BMW and other JB4 applications. Compatible with all BMS JB4 & Stage 1 tuners. Made in USA.

Note we also offer scratched enclosures at a discounted price. Scratched enclosures may have some mild scratches and scrapes from installation or rubbing against other enclosures in the box but still look great and function like new!

Version 1 case bolts are 6-32 x 5/8" and use 7/64" Allen wrench.

Compatible with all JB4 & BMS Stage 1 tuners.
