Blue Arm Restraints

The Blue Arm Restraints by RJS Safety represent a critical safety component for serious motorsports competitors and track-focused drivers who demand professional-grade harness systems. Designed to complement full racing harnesses, these arm restraints prevent uncontrolled arm movement during high-g cornering, braking events, and collisions—a necessity in circuit racing, autocross, and road course environments. Whether you're upgrading an existing racing setup or building a competition-ready interior from scratch, arm restraints are non-negotiable for maintaining driver control and meeting sanctioning body requirements.

These restraints feature individual straps with a robust 1-inch D-ring attachment point, engineered to secure arms against the driver's torso during extreme lateral acceleration. The SFI 3.3 certification ensures compliance with Sports Car Club of America (SCCA) and other major racing sanctioning bodies, meeting rigorous safety standards for impact resistance and material durability. The bright blue color aids in visibility during harness fitting and inspections, while the modular individual-strap design allows custom positioning based on driver ergonomics and cockpit geometry. At 0.94 lbs per unit, the restraints add minimal weight while delivering maximum restraint effectiveness without restricting shoulder articulation for steering inputs.

Professional race car drivers, track day enthusiasts, and motorsports engineers consistently specify RJS arm restraints for vehicles experiencing sustained cornering forces above 1.5 lateral g's. Installation integrates seamlessly with existing multi-point harnesses and roll cage configurations, with the D-ring attachment points routing to the vehicle's main harness anchor or dedicated roll cage mounts. Proper fitment ensures the straps sit snugly against the upper arms without impeding circulation or limiting driver movement—critical for multi-hour endurance events. Check your racing organization's specific harness regulations before purchase, as SFI 3.3 certification covers most SCCA events, club racing, and sanctioned track days across North America.
