BRX01 Evolution: From Trail Legend to the New BRX01 AWB Link

When the original Boom Racing BRX01 launched in 2019, it didn’t just introduce a new truck. It changed the direction of the brand. What began as an in-house project under Asiatees Hobbies quickly captured attention, transforming Boom Racing into a standalone leader in the scale truck industry.

From the very beginning, our mission has been clear: to advance the performance of scale hardbody trucks by designing the chassis and body together from the ground up. Every line, contour, and component serves a purpose, blending realism with capability.

Six Years Later: Enter the BRX01 AWB Link

Six years on, the evolution continues. Boom Racing has unveiled the next chapter in the BRX story, the BRX01 AWB Link.

“AWB” stands for Adjustable Wheelbase, reflecting the growing trend toward modular and customizable builds inspired by the accessibility of 3D printing. The chassis offers adjustable wheelbase options between 265mm and 285mm / 10.4" to 11.2" straight out of the box. With optional parts, builders can extend the wheelbase up to 325mm / 12.8" (for now), giving complete control over stance, proportion, and performance.

In 2019, the first BRX01 with the ZIL hit the trails under Kronik’s hands, and a vision was born.

Adjustable Features

The fully adjustable chassis system is achieved with adjustable rear lower links that can be lengthened to fine-tune wheelbase and suspension geometry to suit your build.

The 7mm Billet Aluminum Adjustable Rails are precision-machined from solid billet aluminum for exceptional rigidity. Unlike traditional adjustable C-channel rails, these join seamlessly without flex or play, ensuring structural strength.

The spline shafts with dual M4 set screws ensure the assembly stays firmly in place. With a little loctite, they're not moving anywhere.

KUDU CVD Driveshafts provide up to 20mm of travel out of the box, offering both strength and smooth articulation across the full range of motion.

Optional Parts for Extended Wheelbase Beyond 285mm / 11.2"

There are multiple ways to adjust the wheelbase on a linked chassis. Below is an approach which extends not just the rear links, but also the chassis rails.

For builders looking to stretch the chassis beyond the standard configuration, up to 325mm / 12.8", the following components are required:

• A pair of longer rear chassis rails (XL or 2XL, extending by 20mm / 0.8" each)

• A pair of longer rear lower link spline shafts (XL 62mm or 2XL 82mm, stock is standard 42mm)

• A longer rear KUDU CVD 116 driveshaft (covers full length from 285-325mm / 11.2"-12.8")

As the time of writing, the KUDU CVD 116 driveshaft is still in production. You may use these alternatives instead:

• Wheelbase 280-300mm / 11.0"-11.8": #BRKD003-107
• Wheelbase 293-319mm / 11.5"-12.6": #BRKD003-119

A detailed wheelbase conversion guide will be published in an upcoming blog post.

Spotlight: ZIL Hardbody Pickup

Now let’s focus on the BRX01 AWB Link with the ZIL Hardbody Pickup, a design that captures the rugged character of 1950s-era pickup trucks.

Highlights include:

• Two-piece ABS hardbody design – The cab and bed are separate units, allowing flexible mounting configurations. You can run the cab alone (from 265mm / 10.4" to 285mm / 11.2") or as a full pickup with bed at 267mm / 10.5"

• Full opening door, hood, and tailgate

• Full LED light buckets included

• Battery box included in the bed

• Rubber mirrors

The cab and bed are built as two separate sections, giving you flexible mounting options and full control over your setup. The battery box is integrated into the bed and disguised as a scale storage box, with the ESC cable cleanly routed through the body for a tidy, realistic look. Which means, battery changes can be done on the trail without removing the body!

The FLEX is real

Three years is a long wait for a new linked chassis from Boom Racing, but the AWB Link makes it worth every second. Trail performance is back, and it looks better than ever.

We were out running and testing her in the Sonoran Desert, life can't beat that!

Final Verdict

The BRX01 AWB Link represents more than just an update. It is a new platform for creators, builders, and trail enthusiasts who want to customize every aspect of their rig.

Stay tuned for our in-depth wheelbase conversion guide and the release of the longer components. The next evolution of BRX engineering is here: built to adapt, engineered to perform.
