Common Applications

The 326POWER 3D☆STAR Alphard Rear Under Spoiler is designed as a lower rear styling upgrade for Toyota AGH/GGH3# Alphard Late Model vehicles equipped with the Aero Grade body configuration.

It is suitable for customers who want to give the rear bumper more visual depth without replacing the complete factory bumper.

The three-dimensional diffuser-style design adds a more customized and substantial appearance to the lower rear section while retaining the recognizable factory Alphard body shape.

The Rear Under Spoiler can be installed as an individual aero upgrade or combined with the matching 3D☆STAR Front Under Spoiler and Side Under Spoiler for a coordinated front, side, and rear exterior setup.

Final compatibility depends on vehicle specification, Aero Grade bumper configuration, body condition, mounting areas, alignment, and installation method.

326POWER Character

326POWER is known for distinctive Japanese tuning style, lowered vehicle setups, stance culture, and bold aero products designed to give modified vehicles a stronger visual identity.

For the Alphard, the 3D☆STAR concept takes a more mature and luxury-focused direction.

Rather than using an overly aggressive full-bumper design, the aero components are added to the lower areas of the factory Aero Grade bodywork, allowing the original Alphard shape to remain recognizable while creating a lower and more customized appearance.

The overall styling direction is strongly influenced by European design, giving the Alphard a premium yet modified character.

3D☆STAR Alphard Design Notes

The 3D☆STAR Alphard lineup was developed to mount to the lower section of the factory Aero Grade body.

The official design concept focuses on visually emphasizing a lower stance while keeping the aero dimensions practical enough for a driven vehicle.

The front and side components use relatively simple forms, allowing the more complex front and rear sections to stand out.

For the rear, 326POWER intentionally chose a more three-dimensional design to balance the overall vehicle.

Rear Diffuser Design

The Rear Under Spoiler uses a diffuser-shaped form with strong three-dimensional detailing.

The factory Alphard rear bumper has complex curved surfaces, so the spoiler was designed to cover and work with those curves rather than simply adding a flat extension underneath the bumper.

This creates a more integrated appearance and gives the lower rear area additional depth.

The design also follows the Euro-style direction used throughout the 3D☆STAR Alphard concept.

Paint separation can be used to further emphasize the diffuser shape and three-dimensional sections of the spoiler.

Final paint design and color separation can be selected according to the customer’s preferred vehicle style.

Installation and Fitment Notes

This Rear Under Spoiler is designed for Toyota AGH/GGH3# Alphard Late Model vehicles with the Aero Grade body configuration.

Before painting, the product must be test fitted to the actual vehicle.

Fitment, alignment, panel gaps, and mounting positions should all be checked and adjusted before final preparation and painting.

If the mounting-hole positions are difficult to align, slight adjustment such as elongated-hole processing may be required during test fitting.

Depending on the individual vehicle condition and installation setup, additional drilling, trimming, sanding, mounting adjustment, or other preparation work may also be required.

Customers should check:

Rear bumper alignment
Lower rear mounting position
Diffuser alignment
Ground clearance
Exhaust clearance where applicable
Mounting-hole positions
Panel fitment
Overall rear alignment

Professional installation and body-shop preparation are strongly recommended.

Aero Product Notes

The product is supplied unpainted in a white gel coat finish.

Installation and painting are not included.

Aero molded products normally require preparation before final painting and installation.

Minor surface irregularities such as pinholes, uneven areas, mold-release marks, or other small molding imperfections may be present and should be corrected during normal sanding and body-shop preparation.

The spoiler should be fully test fitted before painting because installation adjustments should be completed before the final surface finish is applied.

Because this is a lower-mounted rear aero component, ground clearance should also be checked carefully, particularly on lowered vehicles.

Paint Separation Notes

The official 3D☆STAR Alphard design was created with contrasting or separated paint finishes in mind.

Using different finishes on selected diffuser sections can visually emphasize the three-dimensional rear shape and create greater separation between the factory bumper and the added aero component.

The final paint layout is not fixed and can be customized according to the customer’s preferred vehicle style.

Professional paint preparation is recommended to achieve a clean result.
