Return Spring Bushing Kit

The Allstar Performance Return Spring Bushing Kit provides a critical mechanical solution for optimizing throttle linkage geometry on high-performance fuel systems. Designed specifically for applications requiring a 1/2-inch mounting diameter, this kit ensures smooth operation and consistent return-to-idle performance. For builders looking to buy a reliable linkage component, this kit eliminates the friction and binding often associated with worn or substandard bushings in custom throttle configurations.

Constructed from high-grade aluminum with a natural finish, the Return Spring Bushing Kit is engineered to withstand the extreme heat and vibration common within a racing engine bay. The 2-piece design allows for a secure, precise installation on throttle brackets, providing a stable pivot point for return springs. Unlike plastic alternatives that can degrade or melt under pressure, these aluminum bushings offer the long-term durability required for both competitive track use and high-performance street applications.

This comprehensive kit includes all necessary bracket hardware to streamline the installation process and ensure a professional-grade fit. While specifically optimized for use with Holley Carburetors, the universal 1/2-inch mounting specification makes it a versatile addition to various aftermarket throttle setups. Reviewing your linkage alignment is a vital safety step for any mechanic, and this kit provides the technical specifications needed to maintain absolute throttle control.

Weighing just 0.09 lbs, the lightweight Return Spring Bushing Kit minimizes unnecessary mass while maximizing mechanical efficiency. It serves as a direct upgrade for custom throttle setups, ensuring your return springs function without interference or lag. When you choose to integrate Allstar Performance hardware into your build, you are utilizing components specifically tested for the rigorous demands of automotive performance environments.
