Throttle Springs - 5.000 Long - Medium Tension

The Throttle Springs - 5.000 Long - Medium Tension are precision-engineered carburetor linkage components designed for serious engine builders and performance enthusiasts who demand reliable throttle response and consistent fuel delivery. These springs maintain proper tension on throttle butterfly valves and linkage systems, preventing hesitation and ensuring smooth acceleration curves across the entire RPM range. Whether you're tuning a street engine, bracket racing platform, or rebuilding a carburetor assembly, quality throttle springs are essential to eliminating dead spots and mechanical lag.

Manufactured to exacting tolerances, the Throttle Springs - 5.000 Long - Medium Tension 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 where excessive spring pressure can cause linkage binding or accelerated wear on carburetor components. 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. The compact 0.05 lb weight ensures minimal inertia while the 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. Installation is straightforward—simply replace worn or weak springs on existing carburetor linkage assemblies to restore factory tension specifications or upgrade performance characteristics. These springs work universally across most vintage and modern carburetor platforms that utilize standard spring-return throttle mechanisms, making them an economical maintenance solution for anyone rebuilding a carburetor or fine-tuning engine driveability. Stock these medium tension springs for routine service work or as a reliability upgrade during any significant engine overhaul.
