Description
The Simpson Racing Latch & Link Harness – 3” Double Pull-Down 5-Point (3”/2” Shoulder, Clip-In, SFI 16.1) is a premium motorsport restraint system engineered for precision adjustment, maximum safety, and fast installation flexibility. Designed by Simpson Racing, this harness features a patent-pending double pull-down latch & link buckle with integrated clamshell-style adjusters for exceptionally smooth and controlled tightening.
At the core of this system is the advanced latch & link mechanism that allows even tensioning across the lap belts, ensuring a secure and balanced fit under high-performance driving conditions. The molded clamshell adjusters deliver industry-leading smoothness, making belt adjustments quick, accurate, and effortless in any racing environment.
This harness utilizes a 3” lap belt paired with a 3” to 2” shoulder belt transition, optimizing load distribution while maintaining compatibility with HANS, Hybrid, and other frontal head restraint (FHR) systems. The 5-point configuration secures the driver at the shoulders, lap, and anti-submarine strap for improved safety and stability under high G-forces.
The compact buckle assembly is engineered to be one of the smallest and strongest in the industry, enhancing comfort without sacrificing structural integrity. Forged end links for the shoulder and sub belts feature oversized openings and smooth edges for easier engagement and rapid release, even under stress or when wearing gloves.
Shoulder end links position the belts closer together compared to traditional stamped steel designs, improving ergonomics and restraint effectiveness. The sub-belt link provides additional clearance in the groin area for improved 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 enhance visibility in low-light pit conditions.
The clip-in mounting configuration allows for quick installation and removal, making it ideal for vehicles requiring frequent setup changes. Built to meet SFI 16.1 certification standards, this harness delivers professional-grade safety and performance for competitive motorsport use.
