Moker Universal Battery Hold Down Tray for Optima Batteries — Billet Aluminium, Fits Up to 10.5"

The Moker Universal Battery Hold Down is a billet-aluminum base and top-plate kit that securely mounts Optima-style and many standard batteries, keeping them stable in vehicles and relocation boxes.

When relocating or upgrading a vehicle battery, a reliable tray and hold-down system prevents movement, protects terminals, and reduces vibration damage. The Moker Universal Battery Hold Down is engineered to accept common Optima sizes (Red Top, Yellow Top, Blue Top) and other batteries up to 10.5" long using included thread sleeves, delivering a solid, corrosion-resistant solution for cars, trucks, ATVs, and custom installs.

How does the Moker hold-down keep a battery from shifting during travel?

The kit uses a heavy billet-aluminum base plate combined with a top plate and three all-thread rods to clamp the battery securely. This triangular hold-down pattern reduces rocking and lateral movement under acceleration, braking, and off-road conditions.

• Billet aluminum resists impact and deformation.
• Three-point clamping provides even pressure distribution.
• Heavy-duty nuts and sleeves minimize loosening from vibration.

Which battery sizes and types will this tray work with?

Moker designed the tray to be universally compatible with popular Optima formats (34, 34R, 34/78; D34, D34/78; 34M, D34M) and to accept other batteries within the stated footprint. With the supplied thread sleeves, batteries up to 10.5" long, 6.95" wide, and 6.7" high are supported; longer all-thread rods can be substituted for taller batteries.

• Direct support for Optima Red, Yellow, and Blue Top sizes.
• Accommodates batteries up to 10.5" L x 6.95" W x 6.7" H with sleeves.
• Expandable fit using longer all-thread rods for heights over 7.4".

What materials and hardware are included for durability and installation?

The assembly is machined from premium billet aluminum for corrosion resistance and longevity in harsh under-hood or onboard conditions. The package includes everything needed for a basic install so you can mount a battery quickly and securely without sourcing extra parts.

• One billet-aluminum base plate and one top plate for rigid mounting.
• Three all-thread hold-downs with nuts and three thread sleeves included.
• Hardware designed to resist rust and maintain clamp force over time.

How simple is the installation and can it be customized for unique setups?

Installation is straightforward: position the base, set the battery, add the top plate, and tighten the three all-thread rods. Customization is easy—use longer rods or alternate sleeve placements to match relocation boxes, battery trays, or non-standard compartments.

• Complete kit reduces the need for additional fasteners or brackets.
• Thread sleeves allow quick swap between different battery footprints.
• Compatible with relocation boxes and custom-mounted installations.

Who is this for? The Moker Universal Battery Hold Down is aimed at vehicle owners, mechanics, fabricators, and off-road enthusiasts who need a dependable, corrosion-resistant mounting solution for Optima and similarly sized batteries. It’s ideal for those relocating batteries, upgrading to performance batteries, or reinforcing mounts for rugged driving conditions, offering a balance of universal fit, durable material, and a simple installation kit without overcomplicated parts.
