Throttle Return Bracket Black 4150/Edelbrock

The Throttle Return Bracket Black 4150/Edelbrock from ALLSTAR PERFORMANCE is a precision-engineered carburetor mounting bracket designed to manage throttle cable tension and return spring geometry on classic and street performance engines. This component is essential for carburetors featuring square bore configurations, including Holley 4150-style and Edelbrock units, ensuring reliable throttle response and cable routing on engine builds where factory bracket solutions don't fit or proper spring geometry is critical. Built for enthusiasts and professional builders who demand consistent throttle control without cable binding or excessive spring tension.

Manufactured from aluminum and finished in black anodize, this bracket resists corrosion while maintaining a clean, professional appearance in engine bays exposed to heat and moisture. The dual-spring design distributes load evenly across the throttle linkage, reducing fatigue on cable sheaths and improving the consistency of idle and off-idle transitions. The square bore configuration ensures compatibility with Holley 4150 and Edelbrock carburetors, two of the most popular choices in street rod, muscle car, and performance engine applications. Anodized aluminum construction provides durability without adding unnecessary weight—a critical consideration in weight-sensitive builds.

This bracket is ideal for builders installing aftermarket carburetors on modified intake manifolds where OEM throttle return geometry no longer applies, or for those upgrading to dual-carb setups requiring precise cable management. The compact design (4.05 × 1.85 × 17 inches) allows for flexible mounting in tight engine compartments typical of classic builds. Installation pairs seamlessly with carburetor-specific linkage kits and works in conjunction with throttle cables routed through firewall grommet assemblies. Proper throttle return geometry prevents hanging throttle conditions and ensures fail-safe idle control—critical for street safety and engine longevity in high-performance applications.
