Before purchase, every Speedtech Chassis configuration is reviewed by our team to confirm fitment, performance goals, and upgrade compatibility.
Create your build to receive expert validation and final pricing, or share your build goals with a Speedtech specialist to get a custom recommendation.
While Pro Touring often prioritizes peak handling and track capability, our Extreme Street Chassis series is built with a different goal—refined, real-world drivability. Engineered specifically for 1953–1956 Ford trucks, this platform redefines what these classic pickups can be, transforming them from rigid, work-focused machines into smooth, confident street cruisers.
Built on our Extreme Chassis architecture and paired with a Torque Arm rear suspension, this system delivers a balanced combination of ride quality, traction, and control. Updated suspension geometry improves stability, reduces harshness, and enhances steering response, giving these vintage Ford trucks a modern, predictable feel whether you're around town or on extended highway drives.
By combining advanced engineering with the timeless styling of the ’53–’56 Ford platform, the Extreme Street Chassis delivers a clean, composed driving experience without compromising the truck’s original character. The result is a purpose-built foundation designed for comfort, confidence, and long-distance usability.

Oil pan compatibility is application-specific and must clear the steering rack. Consult with a sales representative for proper fitment.
All chassis orders are finalized via phone consultation to ensure proper configuration and fit for your build.
Factory steering columns are not compatible due to length—an Ididit column is recommended for proper integration.
