Seat Back Bracket 70 Deg 1/8in Alum

The Seat Back Bracket 70 Deg 1/8in Alum from ButlerBuilt is a professional-grade weld-on seat mount designed for fabricators, race car builders, and automotive enthusiasts who demand precision seating solutions. This rear-mount bracket serves as the structural foundation for custom and performance seating installations, providing the rigid geometry needed in high-performance vehicles, race cars, and custom builds where factory seat mounting points are unavailable or unsuitable. Whether you're building a dedicated track machine or creating a custom interior for a restomod project, this bracket delivers the engineering-driven reliability that separates quality builds from compromised installations.

Manufactured from 1/8-inch thick aluminum, the Seat Back Bracket 70 Deg 1/8in Alum balances structural strength with weight savings—a critical consideration in performance automotive applications where every pound impacts acceleration, braking, and handling. The 70-degree angle geometry is engineered to provide proper seat back recline and driver positioning while maintaining load-bearing capacity for lateral and longitudinal g-forces experienced during acceleration, cornering, and braking events. The weld-on design eliminates dependency on fasteners or factory attachment points, allowing full customization of seat placement and angle within your vehicle's frame, and the natural aluminum finish accepts welding without surface preparation complications, reducing fabrication time and ensuring reliable joint integrity.

This bracket is essential for builders specifying ButlerBuilt performance seats in custom vehicles, race cars, and specialty automotive projects where OEM mounting infrastructure doesn't exist. Fabricators and mechanics working on tube-frame vehicles, vintage restorations, or purpose-built competition cars will find this component indispensable for achieving both ergonomic seating positions and structural integrity under dynamic driving conditions. Professional installation requires competent welding skills and frame geometry assessment; improper installation compromises both driver safety and vehicle performance. Weighing 1.93 lbs and measuring 9.5 x 1.65 x 16 inches, the bracket integrates cleanly into space-constrained interiors while providing the rigid foundation that separates amateur fabrication from championship-ready builds.
