The Profi II ASM is designed to be used as a four point system. For this reason it is perfect for use in Driver Education cars or any other application where stock seats are retained. A seat that was not originally designed for use with a racing restraint should never be modified to accept an sub strap.

The Profi II ASM incorporates Schroth's® legendary ASM (Anti-SubMarining) technology that is the only thing like it on the market. ASM is an extra fold of material sewn into the right shoulder belt that elongates at a different rate than the outboard belt. This allows your upper torso to twist slightly. On the rebound phase, your torso is planted firmly back in the seat rather than allowed to slide under the lap belt.

The Profi II ASM shoulder is only available in 3" width but is still suitable for use with a Forward Neck Restraint such as a HANS device

You can add a dual sub strap to make this belt into a 6 point at any time. We have recently tested this harness with a HANS device, and the results were great. So you can in fact use this harness with a HANS device.

Specify black, red, blue or silver when ordering.

All Schroth harnesses are the latest date codes available to us directly from Schroth.
