Dual Return Spring Kit

The Dual Return Spring Kit from RACING POWER is an essential component for carburetor and fuel system throttle linkage applications. This kit is ideal for those rebuilding classic muscle cars, restoring vintage trucks, or maintaining street machines, ensuring smooth and predictable throttle response.

Designed with a dual-spring configuration, this kit provides consistent mechanical advantage and redundant tension throughout the throttle travel range. The compact design (3.9 × 1.2 × 8.8 inches) and lightweight construction (0.15 lbs) facilitate easy installation in tight spaces without adding unnecessary weight.

Mechanics and engine builders rely on this kit for carburetor tuning, throttle linkage rebuilds, and performance engine swaps where original springs may be missing or worn. The engineered spring rates are calibrated to restore OEM-spec throttle feel, ensuring reliable performance with each pedal release.
