The GM Dual Throttle Return Spring is a critical carburetor linkage component designed for General Motors vehicles equipped with dual-feed fuel systems or progressive carburetor setups. This stainless steel spring pair restores proper throttle plate closure and idle response when factory springs have lost tension or become corroded. For any serious engine builder or restoration enthusiast, reliable throttle return springs are non-negotiable—they ensure predictable throttle behavior, smooth idle quality, and safe engine operation across the entire RPM range.
Constructed from natural stainless steel, the GM Dual Throttle Return Spring resists rust and corrosion far better than zinc-plated or bare steel alternatives, making it ideal for both street and high-mileage applications where moisture exposure is inevitable. The dual-spring design distributes load evenly across both throttle shafts, preventing binding and uneven plate closure that can cause hesitation or stumbling during light-throttle transitions. Holley's precision engineering ensures consistent spring rates that won't soften or take-set after repeated heating cycles, maintaining throttle response integrity over thousands of miles.
This spring pair fits any GM carburetor application where factory dual-feed linkage is present, including Chevrolet, Pontiac, Oldsmobile, and Buick engines from the 1960s through 1980s. Weighing just 0.08 lbs per pair and measuring a compact 5 x 0.9 x 7 inches, installation requires no special tools—simply unhook worn springs and replace them in minutes. Whether you're tuning a street rod, restoring a classic muscle car, or overhauling an original carburetor setup, these stainless springs deliver the reliability and durability that separates a weekend build from a show-quality restoration.
