FSR One Twenty Aluminum Sim Racing Chassis

The FSR One Twenty is our most popular aluminum profile sim racing chassis, designed and manufactured in Southern California for drivers who want a rigid, refined, and highly configurable foundation for their simulator.

Built from heavy-duty 40x120 black anodized aluminum extrusion, the One Twenty is engineered to support high-torque direct drive wheelbases, advanced pedal systems, and the upgrades that come with a serious sim racing setup. Its clean, bracket-free construction uses precision-drilled extrusion and proprietary cup washers to create a more finished appearance without sacrificing strength or adjustability.

Rather than treating the chassis as a collection of generic aluminum profiles, the One Twenty is designed as a complete simulator platform. Purpose-built pedal risers, multiple wheelbase mounting configurations, and a modular accessory system allow the cockpit to be configured around your current hardware and adapted as your simulator evolves.

Designed for Direct Drive Sim Racing Hardware

The FSR One Twenty is built for modern sim racing equipment, including high-torque direct drive wheelbases, load-cell pedals, hydraulic-style pedals, active pedal systems, shifters, handbrakes, button boxes, and other simulator accessories.

Its rigid aluminum profile construction helps reduce unwanted movement under heavy braking and aggressive steering inputs, while maintaining the adjustability needed to create a comfortable and repeatable driving position.

Wheelbase compatibility depends on the mounting configuration selected. If you are unsure which option is correct for your wheelbase, contact Focus Sim Racing before ordering and we will help confirm the proper setup.

Purpose-Built Pedal Mounting System

The One Twenty uses laser-cut steel pedal risers with indexed adjustment slots, allowing the pedal position and angle to be configured around the driver and pedal system. Ball-bearing T-nuts make adjustments easier while helping maintain a secure connection to the chassis.

The pedal area is designed to support a wide range of sim racing pedals, from traditional load-cell systems to hydraulic-style pedals and advanced active pedal hardware.

Modular and Upgradeable

The aluminum profile design allows the FSR One Twenty to grow with your simulator. It can be configured for a focused single-monitor setup, a triple-screen racing simulator, or a more advanced build with additional controls and accessories.

Compatible Focus Sim Racing accessories include monitor stands, shifter mounts, handbrake mounts, keyboard and mouse accessories, electronics management solutions, PC shelves, and other modular components.

Clean, Bracket-Free Construction

The One Twenty uses precision-drilled extrusion and proprietary hardware to reduce the number of visible external brackets typically found on generic aluminum profile rigs. This creates a cleaner, more integrated appearance while preserving the strength and modularity of an aluminum chassis.
