RaceQuip's 5-Point Camlock Harness System features 2" shoulder and lap belts and carries an SFI 16.1 Rating. The 2" twin individual shoulders allow use with any Head & Neck Restraint Device and the 2" lap belt means that the belt can tuck below your hip bone instead of on top of it. This allows a tighter lap belt and it will load more quickly in the event of an impact. The lightweight aluminum alloy cam buckle provides precise spring pressure for a positive feel when rotating the lever to the 45 degree (right or left) unlatch movement. This motorsports seat belt system also has a "pull down" lap belt design which means you pull the lap belt ends away from the cam buckle to tighten the belts
