Schroth Racing Rallye 3 ASM Safety Harnesses

Schroth Racing Rallye 3 ASM Harnesses — Street-Legal Anti-Submarining 3-Point Safety Belts

The Schroth Racing Rallye 3 ASM Harness is a premium street-legal 3-point harness system designed to offer enhanced safety, comfort, and fitment for vehicles where a traditional 4-point harness won’t fit or install properly — especially when the rear seat is too close to the front seats for ideal geometry. Schroth’s ASM (Anti-SubMarining) technology includes a built-in anti-submarine flap in the inboard shoulder belt that helps prevent the wearer from sliding forward under the lap belt in a collision, significantly improving occupant restraint performance compared with basic 3-point belts. The harness uses 50 mm (2 in.) wide shoulder and lap webbing, bolts into factory-tested mounting points, and maintains usability of the vehicle’s stock seat belt when needed.

Available in multiple colors with quick-disconnect tail straps for ease of use, these harnesses are DOT/ECE/FMVS-approved for street use and ideal for spirited driving, rallying, or autocross where extra security without the complexity of a full 4-point harness is desired.
