Mounting Plate Seat Belt Back-Up Plate

The G-FORCE Mounting Plate Seat Belt Back-Up Plate (model 100H) is a precision-engineered steel reinforcement component designed to distribute harness loads across vehicle seat structures during high-performance driving and motorsports applications. This back-up plate provides critical structural support behind seat belt mounting points, preventing localized stress concentration and seat frame damage when harnesses are subjected to sustained lateral or emergency braking forces.

Constructed from solid steel in natural finish, the plate measures 4.6 x 0.3 x 6.95 inches and features a 7/16-inch seat belt mounting hole compatible with standard racing harness anchor points. The 0.3-inch thickness provides adequate rigidity to support dynamic loads without excessive mass. At 0.55 pounds, the component adds minimal weight while significantly improving harness mounting durability. Installation requires basic hand tools and takes minutes to complete on most vehicles with accessible seat-mounted harness locations.

This back-up plate is essential for track-focused builds, rally vehicles, and any application where aggressive driving generates high harness tension. It's particularly valuable when retrofitting racing harnesses to factory seat structures that lack reinforced mounting points. The steel construction resists deformation from repeated harness cinching and ensures anchor points remain stable throughout the vehicle's service life. Buyers seeking to upgrade harness security without extensive seat modification will find this plate an economical, direct solution that meets industry motorsports standards.
