RBZ Harmony DC5 / RSX Antigravity ATX-20 Battery Relocation Tray

A precision relocation tray that moves the Antigravity ATX-20 or ATX-20HD lithium battery to the front of the transmission, opening up the original location for a cold air intake or other engine bay components. Laser cut from a single sheet of 5052 aluminum and formed through carefully placed bends. Finished in Cerakote with Japanese Industrial Standards (JIS) Grade 10.9 hardware and genuine Nord-Lock wedge locking washers. Designed and finished at our Florida Atelier.

🟤 Intake Clearance — Relocates the battery to the front of the transmission, opening the original location for a cold air intake or charge pipe routing.

🟤 Single Piece Construction — The entire tray comes from one sheet of 5052 aluminum, laser cut and formed through precise bends. No welds, no separate components.

🟤 Designed for Antigravity Lithium — Engineered around the Antigravity ATX-20 and ATX-20HD dimensions for a secure, deliberate fit.

🟤 Direct Bolt-On — Mounts to factory chassis locations. No cutting, drilling, or fabrication.

🟤 OEM Wire Harness Retained — The relocation position preserves the original wire harness length. No extension, no rewiring.

🟤 RE-START Access — The tray positions the battery so the Antigravity built-in jump start feature remains fully accessible.

🟤 Premium Hardware — Japanese Industrial Standards (JIS) Grade 10.9 bolts and genuine Nord-Lock wedge locking washers, the same hardware trusted in aerospace and rocket engines.

🟤 Cerakote Finish — Ceramic based coating originally developed for military use. Resists chips, heat, chemicals, and UV fading well beyond standard powder coat.

🟤 Laser Engraved Markings — Torque specifications and part identification engraved directly into the tray.

The Design

The entire structure comes from a single sheet of 5052 aluminum, cut with laser precision and shaped through a sequence of intentional bends. The internal cutouts reduce weight while keeping the geometry rigid. No welds, no assembly, no compromises in the load path.

Fitment

Designed for the Acura RSX (DC5 chassis) with any K-series engine. Compatible with the Antigravity ATX-20 and ATX-20HD batteries. For other battery models or chassis, send us a message before ordering.

Crafted, Not Just Manufactured

At RBZ, we approach every part the way a jeweler approaches their work, with patience, precision, and pride in the detail. Each tray is laser cut, formed, finished, and inspected before it leaves the shop. The clean folds, the engraved markings, the texture of the Cerakote, all of it is intentional.

Engineering is the foundation of everything we make, but craftsmanship is what gives our parts their character. Even the smallest pieces in our catalog ship in a 3D printed presentation case with a carbon fiber textured finish, designed in-house with fitted cutouts for each component. From the packaging to the smallest fastener, the experience is meant to feel considered, not assembled.

We see our work less like a product line and more like a small gallery, pieces built to perform, designed to last, and finished to be admired.

Frequently Asked Questions

What chassis does this fit? The Acura RSX, DC5 chassis. Base and Type S variants.

What batteries does this work with? Antigravity ATX-20 and ATX-20HD lithium batteries. The tray is dimensioned around those exact models.

What is the tray made from? A single sheet of 5052 aluminum, laser cut and formed through precision bends. The entire structure comes from one piece of material.

Why 5052 aluminum? A marine grade alloy with excellent strength to weight, formability, and corrosion resistance. It holds bends without cracking and resists the engine bay environment over time.

Will I need to extend the wire harness? No. The relocation position is designed so the OEM wire harness reaches without modification.

Will the Antigravity RE-START feature still work? Yes. The tray positions the battery with the RE-START button and indicator lights fully accessible.

Do I need to cut or drill anything? No. The tray bolts directly to existing chassis points. The install is reversible.

What makes the hardware different from typical aftermarket? Japanese Industrial Standards (JIS) Grade 10.9 bolts with genuine Nord-Lock wedge locking washers. Nord-Lock washers are used in aerospace and rocket engine applications because their wedge geometry holds joints secure under extreme vibration.

Why Cerakote instead of powder coat? Cerakote is a ceramic based coating originally developed for military applications. It is thinner than powder coat but significantly more durable, with better resistance to impact, heat, chemicals, and UV fading.

Does the kit include the battery? No. The Antigravity battery is sold separately, sourced directly from Antigravity or an authorized dealer.

Where is this made? Designed, laser cut, formed, and finished at our Florida Atelier.
