Focus Sim Racing FSR One Twenty Sim Racing Chassis
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.

FSR One Twenty vs Other Aluminum Chassis
There are several strong aluminum profile chassis on the market. The difference with the FSR One Twenty is the complete platform approach. Instead of buying a generic frame and figuring out the rest later, the One Twenty is designed around clean construction, dedicated mounting options, FSR accessories, showroom support, assembly options, and a long-term upgrade path.
If you want a rigid chassis that can grow with your hardware while still looking clean and intentional, the FSR One Twenty gives you a professional-grade foundation backed by real sim racing support. For customers building an even larger, motion-focused, or top-tier simulator, the FSR One Sixty is available as our flagship chassis platform.
Are FSR Accessories Universal
FSR chassis accessories are designed first around the FSR chassis platform. Some parts may fit other aluminum profile rigs, but compatibility with third-party chassis can vary. For the cleanest fit, best hardware integration, and full upgrade path, we recommend building around the FSR One Twenty platform.
