Throttle Springs - 5.000 Long - Medium Tension

The Throttle Springs - 5.000 Long - Medium Tension are precision-engineered components designed for serious engine builders and performance enthusiasts who demand reliable throttle response and consistent fuel delivery. These springs are essential for maintaining proper tension on throttle butterfly valves and linkage systems, preventing hesitation and ensuring smooth acceleration across the RPM range.

Manufactured to exacting tolerances, the Throttle Springs feature a carefully calibrated spring rate that balances return force against durability. The medium tension rating makes these springs ideal for stock-to-moderately-modified engines, as excessive spring pressure can lead to linkage binding or accelerated wear on carburetor components. Their durable construction resists corrosion and fatigue from thousands of throttle cycles.

Mechanics and engine builders choose these springs when restoring or upgrading fuel system responsiveness on carbureted engines. At 5.000 inches in overall length, they fit standard two-barrel and four-barrel carburetor return spring applications common across domestic and imported performance platforms. Installation is straightforward—simply replace worn or weak springs to enhance performance.
