IRURI HILLS · LAND CRUISER LC250 / PRADO 250

A Lower Profile.
A Connected Structure.

The IRURI HILLS Low-Profile Roof Rack is developed for the Toyota Land Cruiser LC250 / Prado 250 as a complete structural roof platform.

A round-tube frame forms the primary structural architecture. Precision 5-axis CNC-machined nodes define critical connection interfaces, while fabricated sheet-metal components integrate the frame with vehicle-specific mounting locations.

Together, these three manufacturing approaches create a modular roof system developed around interlocking structural geometry, multiple load paths and factory-point installation without drilling.

Tubular Structural Frame

The Frame Begins
with the Tube.

Round tubular members form the primary structural network of the roof rack.

Rather than treating each crossbar as an isolated component, the surrounding frame and transverse members work together to establish a connected roof-platform architecture.

This connected structure provides the foundation for the CNC-machined nodes and creates multiple structural paths across the assembled roof rack.

5-Axis CNC Structural Connection Geometry

The Tubes Form the Frame.
CNC Defines the Connection.

Key structural connection nodes are manufactured through 5-axis CNC machining.

Multi-directional machining produces defined receiving geometry, locating surfaces and connection interfaces used to position adjoining tubular members.

These machined interfaces help establish the relative position and alignment of connected structural components before final mechanical fastening.

Mortise-and-Tenon-Inspired Structural Logic

The Geometry
Defines the Joint.

The roof rack incorporates an interlocking connection principle inspired by traditional mortise-and-tenon construction.

Tubular members engage with defined receiving geometry within the CNC-machined structural nodes before final mechanical fastening.

This allows the connection geometry itself to contribute to component positioning and mechanical engagement, rather than relying only on flat surface contact and fasteners.

Precision-Fabricated Mounting Components

Formed Where the Frame
Meets the Vehicle.

The roof rack also incorporates precision-fabricated sheet-metal components within its mounting and support architecture.

Cut and formed brackets provide mounting surfaces, structural transitions and connection geometry between the tubular frame and compatible vehicle mounting locations.

Sheet-metal fabrication complements the CNC-machined structural nodes by creating formed components where broad mounting surfaces and vehicle-specific bracket geometry are required.

Multi-Point Structural Load Distribution

Multiple Members.
Multiple Load Paths.

The rack is developed around a connected structural network rather than isolated mounting members.

Round tubes establish the primary structural paths. CNC-machined interlocking nodes connect adjoining members, while the sheet-metal mounting architecture links the frame to multiple vehicle attachment positions.

This layout is designed to help distribute applied forces through multiple connected structural members and mounting interfaces, reducing reliance on a single isolated connection point.

IRURI Proprietary Patented Fade-Resistant Surface Treatment

Engineered for
Long-Term Color Stability.

A roof rack remains continuously exposed to sunlight, moisture, washing, temperature changes and prolonged outdoor use.

Finished exterior metal components use IRURI's proprietary patented fade-resistant surface treatment, engineered for long-term color stability and to help resist visible fading and discoloration associated with prolonged outdoor exposure.
