Throttle Springs - 2.500 Long - Medium Tension

The PAC Racing Springs Throttle Springs – 2.500 Long – Medium Tension is a precision-engineered throttle return spring designed for high-performance engine applications where reliable, consistent spring force is critical to safe operation. With a 2.5-inch free length and medium tension rating, this spring from PAC Racing Springs provides the controlled return force necessary to ensure your throttle linkage responds predictably under varying engine loads and operating conditions.

Manufactured from steel in a natural finish, this PAC-3002 throttle return spring is engineered to deliver consistent performance across extended operating cycles. Medium tension springs occupy a critical middle ground in spring selection—offering sufficient return force to prevent throttle hang or sluggish response while avoiding excessive spring pre-load that can strain linkage components or require excessive pedal pressure. The specific 2.5-inch length specification ensures compatibility with throttle cable systems designed for this dimension, critical for proper geometry and mechanical advantage in your fuel delivery system.

This spring is essential for engine builders, performance shops, and enthusiasts assembling or rebuilding throttle control systems where OEM or equivalent springs have fatigued. Applications range from street performance engines to racing platforms where repeatability and durability under sustained use matter. Proper throttle return spring selection directly affects drivability, safety, and the longevity of your throttle linkage system. Sold as a single unit, allowing builders to purchase exactly the quantity needed for their project without waste.
