This Latch & Link System is the original military aircraft design latch system that was adapted for motorsports many years ago. Latch components are drop forged alloy steel for strength and durability. Shoulder and lap belts are made of standard 3" military spec webbing, and belt adjuster mechanisms include anti-slip spring as standard issue. This harness has a rugged leather skirting attached behind the latch mechanism to provide extra built-in comfort. This is Simpson's original racing harness designed for maximum reliability and affordability.
