Diode Dynamics DD8523 DEK 4Runner 2010 Roof Rack with SS40 Sport Dual-Color LED Light Bar Combo

The Diode Dynamics x Kuat DEK Roof Rack is a custom-fabricated, integrated lighting roof rack system designed specifically for the Toyota 4Runner. Purpose-built as a collaboration between Diode Dynamics and Kuat, the DEK seamlessly incorporates an SS40 Stage Series Dual-Color LED light bar directly into the rack structure for a clean, OEM-style appearance that sets it apart from bolt-on aftermarket alternatives.

Adventure-Ready Construction

Built from durable all-metal construction, the DEK features a modular, low-profile design with adjustable crossbars that clear antennas and sunroofs. Generous T-channels run the length of the rack for mounting accessories, gear, and recovery equipment. Installation is straightforward with a direct-mount system — no drilling required. The rack supports up to 300 lbs of rooftop cargo capacity.

SS40 Stage Series Dual-Color LED Light Bar

This combo includes the SS40 Sport Dual-Color Stage Series LED light bar, which mounts directly into the integrated rack channel for a low-profile, streamlined look. The SS40 features a Combo/Driving beam pattern engineered to blend forward distance and side-to-side width into one balanced, even output. Unlike traditional reflector-based designs, Diode Dynamics' patented TIR optics capture and focus nearly all light output precisely where it's needed — eliminating glare and wasted light.

Dual-Color Functionality with SmartSelect Technology

The Dual-Color configuration combines amber outer segments with selectable multicolor inner segments. Using patented SmartSelect technology, the light bar allows you to run the inner segments only, outer segments only, or the full bar — all without additional wiring or extra switches. Simply cycle the main beam power to select your preferred mode. The inner segment backlight is user-selectable from eight colors, including a true amber option via a dedicated amber chip, and includes a dynamic startup sequence each time the light is powered on.

Fully Illuminated Backlight

Both the amber outer segments and the selectable multicolor inner segment feature a fully illuminated backlight that lights up the TIR optics even when the main beam is off, providing a distinctive accent lighting appearance day or night.
