Bonbo Billet Aluminum Battery Tray for Optima 34/34M/D34 Batteries — Low-Profile Trunk Hold-Down, Corrosion-Resistant

Bonbo's billet aluminum battery pallet is a compact, corrosion-resistant trunk hold-down bracket engineered to secure Optima Blue, Red, and Yellow Top batteries (34/34M/D34/D34/78) safely and neatly in racing and street vehicles.

This precision-machined battery tray replaces flimsy stock mounts with a low-profile, embedded design that holds Optima battery group sizes with a tight fit and minimal movement. Machined from billet aluminum for high torsional strength and corrosion resistance, the tray includes all mounting hardware so you can install it quickly. It supports Blue Top 34M/D34M, Red Top 34/34/78 (not 34R), and Yellow Top D34/D34/78 (not D75 75), and measures 11.2 x 7.9 inches for reliable compatibility.

How does this tray secure my Optima battery during spirited driving?

The Bonbo tray uses an embedded base and sturdy hold-down tabs to lock the battery in place, reducing lateral and vertical movement. Its billet aluminum construction resists flex under load so the mounting points remain stable during cornering and bumps.

• Embedded tray footprint sized to fit Optima 34/34M/D34 series batteries.
• Two fixing hold-down tabs clamp the battery tightly against the base.
• Billet aluminum resists torsion and maintains clamping pressure when heated.
• Includes bolts, nuts, and washers for secure installation.

Will it fit my particular Optima battery model?

The tray is tailored to Optima group sizes commonly used in trunks: Blue Top 34M and D34M, Red Top 34 and 34/78, and Yellow Top D34 and D34/78. It does not fit Optima 34R or D75 75 models, so verify your battery label before ordering.

• Compatible: Blue Top 34M, D34M; Red Top 34, 34/78; Yellow Top D34, D34/78.
• Not compatible: Optima 34R or D75 75 batteries.
• Tray outer dimensions: 11.2 x 7.9 inches for exacting fit checks.
• Embedded design reduces the need for extra padding or shims.

What hardware and parts come with the Bonbo battery pallet?

The package arrives ready to mount: you get the tray plus a complete fastener kit that covers typical trunk installation needs. The included fasteners are sized to secure the tray to varied factory anchor points or aftermarket relocation brackets.

• 1 x billet aluminum battery tray (11.2 x 7.9 inches).
• 6 nuts, 6 x 8mm bolts, 4 x 10mm bolts, and 4 washers.
• 2 fixing hold-down tabs to clamp the battery.
• All parts required for a standard trunk install—no missing pieces.

How does the material and finish affect longevity and maintenance?

Machined from high-grade billet aluminum, the tray resists rust and corrosion better than steel alternatives, which lowers long-term maintenance. The solid aluminum body preserves structural strength under heat and vibration, and it’s easy to wipe clean after installation.

• Billet aluminum construction prevents rust and extends service life.
• High torsional strength reduces flex and stress at mounting points.
• Smooth finish resists dirt and simplifies periodic inspection.
• Lightweight compared with steel while remaining rigid.

Who is this for? Car owners and racers who relocate or mount Optima battery group 34-series in trunks, engine bays, or custom compartments and need a durable, low-profile hold-down solution. It's ideal for enthusiasts upgrading from weak or corroded stock brackets, builders fitting batteries into custom trays, and anyone who wants a secure, long-lasting mount that comes with the correct hardware for quick installation.
