Schroth Profi II ASM Flexi Harness

Product Description

The Schroth Profi II ASM 4 Point Harness is a professional clip-in motorsport harness designed for secure driver restraint in track day, competition and performance applications. Featuring ASM anti-submarining technology, it is designed to help reduce the risk of the driver sliding under the harness during a frontal impact.

The harness uses 3” shoulder straps for strong upper body support, with lightweight quick adjusters to make fitment and tightening easier. The 2” lap straps provide a secure and comfortable fit around the pelvis, with clip-on end fittings for use with suitable harness mounting points.

A compact aluminium rotary buckle provides quick, positive engagement, with an ergonomic release lever for easy operation. The harness is supplied with 4 eyebolts, giving you the required clip-in mounting hardware for compatible installations.

The Schroth Profi II ASM harness is FIA 8854/98 approved and is handed, meaning you must choose the correct version for the side of the car it will be fitted to.

Please confirm seat compatibility, harness mounting points, belt routing, harness side, motorsport regulations and intended use before ordering.
