Description
The Simpson Racing Latch & Link Harness – 3” Double Pull-Down 5-Point (Bolt-In, SFI 16.1) is a high-performance motorsport restraint system engineered for maximum safety, precision adjustment, and long-term durability. Developed by Simpson Racing, this harness features a patent-pending latch & link design with integrated clamshell-style adjusters for exceptionally smooth and controlled belt tightening.
At the core of this system is the advanced double pull-down latch & link buckle, designed to provide even tension across the lap belts for a secure and balanced fit. The molded clamshell adjusters deliver industry-leading smoothness, allowing for precise adjustments with minimal effort in demanding racing environments.
This harness utilizes a 3” lap belt paired with a 3” to 2” shoulder belt configuration, optimizing load distribution while maintaining compatibility with HANS, Hybrid, and other frontal head restraint (FHR) systems. The 5-point configuration secures the driver across the shoulders, lap, and anti-submarine strap, ensuring proper restraint under high G-forces.
The compact buckle assembly is engineered to be one of the smallest and strongest in the industry, improving comfort without sacrificing structural integrity. Forged end links for the shoulder and sub belts feature oversized openings and smooth edges, allowing for easier engagement and quick release even under stress.
Shoulder end links are designed to position the belts closer together compared to traditional stamped steel systems, improving ergonomics and restraint effectiveness. The sub-belt linkage provides additional clearance in the groin area, enhancing comfort during extended driving sessions.
Constructed from high-strength, low-elongation webbing, this harness ensures durability and minimal stretch under load. Lightweight aluminum shoulder adjusters provide smooth operation and reduced weight, while the silver latch handle and end fittings improve visibility in low-light pit conditions.
The bolt-in mounting configuration provides a permanent and secure installation, making it ideal for dedicated track and race vehicles. Built to meet SFI 16.1 certification standards, this harness delivers professional-grade safety and performance for competitive motorsport use.
