Stud Bushing

The Holley Stud Bushing (Part Number 26-103) is a two-piece throttle linkage bushing engineered to provide smooth, wear-resistant operation in carburetor throttle systems. Constructed from nylon in black and white, this bushing accommodates a 1/2-inch mounting diameter and functions as a universal fit component across multiple carburetor and throttle linkage configurations. The two-piece design allows for easy installation and service while maintaining precise throttle response without play or binding.

Nylon construction offers critical advantages in throttle linkage applications: it resists corrosion from fuel vapors and moisture, eliminates metal-to-metal wear that can degrade throttle feel over time, and reduces noise from linkage movement. The 1/2-inch mounting diameter is the industry standard for most Holley carburetors and compatible throttle cable systems. As a wear item, this bushing should be inspected periodically and replaced when visible fraying, cracking, or excessive play develops—typical wear intervals range from 2–5 years depending on climate and driving frequency.

This bushing kit is essential for hot rod builders, classic car restoration shops, and carburetor maintenance programs where reliable throttle actuation directly affects engine response and drivability. Holley's reputation in fuel system components makes this OEM-specification replacement a proven choice for both performance and stock applications. The compact weight (0.02 lbs) and modest dimensions (3.5 × 1.15 × 4.95 inches) allow for efficient storage and rapid installation as part of routine carburetor service or complete linkage rebuild kits.
