Field Test Program — Slots Open

Join the Program.

At Bushido Performance, our engineering focus is simple: increasing the service life of our components. We believe that everything we build should withstand the rigorous demands of daily operation, which is why we’ve developed our program to validate our designs in real-world environments. We are currently seeking owner-operators and fleet drivers to integrate our pre-release components into their active routes. This is a collaborative process designed to gather the long-term durability data that standard shop testing cannot replicate. There is no cost to participate. We provide the hardware, you oversee the installation and a 90-day evaluation period, and in return, you keep the equipment completely free. Your professional feedback is the final step in our development cycle, ensuring every part we release meets our standards for reliability and performance.

The Field Evaluation Process

Step 01

Vehicle Configuration and Application

Submit your truck's make, model, and year along with a brief overview of your typical routes and duty cycles. This information ensures the hardware is a match for your specific operation. Once your application is approved, you will receive a formal Field Test Agreement to sign electronically and finalize your enrollment.

Step 02

Shipment and Installation Photos

After the agreement is signed, we will ship the hardware to your location at no cost. To establish a baseline for the evaluation, we require a few high resolution photos or a brief video of the initial installation. This confirms the part is mounted correctly and ready for service.

Step 03

Monitoring and Safety Protocol

Check the hardware as part of your standard daily inspections, looking for any changes in fitment or signs of wear. For your safety and the integrity of our testing, if you notice any performance issues or material stress, the part must be removed immediately and reported to our team for analysis.

Step 04

Final Feedback and Reporting

The evaluation concludes after 90 days with the submission of your Final Performance Report. We require before and after photos and your honest feedback on the durability of the part. Most importantly, we want to know what can be improved. Your insights on how to make the design better are the final step in our development process.

Step 05

Equipment Retention

Once your final report is reviewed, the testing phase is officially closed. As a thank you for your time and contribution to our standards, the hardware remains on your vehicle as your property completely free of charge.

Freightliner Cascadia Cab Extender Attachment Arm

Freightliner CascadiaPT-126 2018–2024

This aftermarket attachment arm (Part # 22-74370-000) is a high performance replacement for the Freightliner Cascadia PT-126 (2018–2024) and is designed to secure the left lower cab extender fairing to the cab structure. While it replaces OEM reference 9999-0490, it moves away from standard factory plastics in favor of Carbon Fiber Reinforced Plastic. This material upgrade offers significantly higher structural rigidity and durability, specifically engineered to withstand the constant wind buffeting and vibration of long haul highway miles that often cause factory arms to fatigue.

We are currently looking for Cascadia fleet operators and owner operators to run this arm against their current OEM hardware and report on its real world performance. A key distinction of this part is its precision engineering; it is built to much tighter tolerances than the original factory arm. Because of this, the fitment will feel intentionally firm during installation. This design choice directly addresses the common issue of loosening and sagging that develops in OEM arms over time, ensuring the fairing maintains its aerodynamic position from the first mile to the last. Your feedback on how this carbon fiber composite holds up under pressure will be the primary driver for our next production cycle.

Freightliner Cascadia Cab Extender Small Bracket

Freightliner CascadiaP4 2008–2018 / PT-126 2018–2023

This aftermarket cab extender fairing mounting bracket (Part # 22-73952-000) is a reinforced replacement for OEM reference 9999-0491. It is designed to clip into the left lower cab extender assembly alongside the attachment arm (22-74370-000). While the original factory brackets are made from standard plastic, our version is built from Carbon Fiber Reinforced Plastic for much higher strength and a longer service life. This bracket is compatible with both the P4 (2008–2018) and PT-126 (2018–2024) generations of the Freightliner Cascadia.

We are looking for Cascadia fleet operators and owner operators to field test this bracket against the OEM version and provide feedback on its durability in real world conditions. Like the companion attachment arm, this bracket is engineered to tighter tolerances than the factory original. This means the fit will feel intentionally firm during installation. We built it this way because OEM brackets often loosen over time, leading to fairing vibration; our goal is a fit that stays secure for the life of the part. Your performance reports will help us refine the design for our upcoming production runs.
