Seat Back Bracket 70 Deg 1/8in Alum

The Seat Back Bracket 70 Deg 1/8in Alum from ButlerBuilt is a precision-engineered component designed for drivers and fabricators who demand adjustability and reliability in high-performance seating configurations. This aluminum bracket serves as the foundation for custom seat installations in race cars, track-focused builds, and professional motorsport applications where seat positioning directly impacts driver comfort and safety during extended driving sessions.

Constructed from durable 1/8-inch aluminum, this seat back bracket features a 70-degree angle geometry that provides optimal ergonomic support while minimizing package constraints in tight cockpit layouts. The aluminum construction balances weight savings against structural rigidity—critical for vehicles where unsprung and rotating mass directly affect handling dynamics and acceleration. ButlerBuilt's design allows fine-tuned seat positioning by leveraging the 70-degree angle to achieve proper hip and shoulder support angles, reducing driver fatigue during competition or spirited driving and improving control input response.

Professional fabricators, motorsport enthusiasts, and independent mechanics rely on this bracket when building or modifying race-spec seating systems in street cars, track machines, and competition vehicles. Installation requires welding or bolted attachment to the vehicle's frame or existing seat structure, making it suitable for custom roll cage integration and aftermarket seat mounting solutions. The compact footprint (9.5 x 1.65 x 16 inches) and lightweight profile (1.93 lbs) make it ideal for weight-conscious builds where every pound matters, while maintaining the structural integrity needed for sustained lateral and longitudinal forces in high-performance driving scenarios.
