Bronze Throttle Shaft Bushings (8)

The Bronze Throttle Shaft Bushings (8) set from Advanced Engine Design represents a critical wear item for any serious engine builder or performance mechanic working on high-mileage carbureted or early fuel-injected platforms. These bushings support the throttle shaft—the rotating shaft that controls fuel and air delivery—and are prone to excessive wear over decades of use. When throttle shafts develop play due to worn factory bushings, you'll experience poor idle quality, hesitation, and difficulty maintaining consistent fuel mixture. This eight-piece set addresses that problem directly, restoring the precision fit your engine demands.

Bronze bushings are the ideal choice for throttle shaft applications because bronze offers superior wear resistance, self-lubricating properties, and dimensional stability compared to inferior plastic or worn cast-iron originals. The bronze material naturally accommodates the sliding action of the throttle shaft without galling, while maintaining tight tolerances that eliminate the sloppy feel that develops in tired carburetors. Each bushing in this eight-piece assortment is precision-manufactured to restore factory specifications, ensuring smooth throttle response and repeatable idle behavior. The compact, lightweight design (0.06 lbs total) makes installation straightforward during any carburetor rebuild or throttle body restoration project.

This bushing set is essential for restoring classic muscle cars, street rods, vintage trucks, and any carbureted engine that has seen extended service. Whether you're performing a complete carburetor rebuild or just refreshing an aging throttle assembly, these Advanced Engine Design bushings guarantee the shaft movement remains crisp and responsive. Installation requires basic carburetor knowledge and hand tools; most experienced mechanics complete the job in under an hour. For buyers seeking to eliminate idle stumble, erratic throttle feel, and worn-out performance characteristics, the Bronze Throttle Shaft Bushings (8) deliver proven results at a fraction of the cost of a complete carburetor replacement.
