Each spring is color-marked for easy identification and made in the United States to Edelbrock specifications. The small, lightweight pack contains one of each resistance commonly used for tuning, so you can test different rates without ordering individual parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these springs change throttle or shift behavior?\u003c\/h3\u003e\n\u003cp\u003eStep-up springs alter the force needed to move a linkage or valve, so swapping to a lighter or heavier spring changes how quickly the mechanism reacts. Using a firmer spring increases resistance and delays or firms the action, while a softer spring makes it respond sooner or with less force. That lets you tune drivability, shift feel, or kickdown timing to match engine output and driver preference.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes five resistance levels for incremental adjustments.\u003c\/li\u003e\n  \u003cli\u003eColor-coding (blue, yellow, orange, pink, plain) speeds selection.\u003c\/li\u003e\n  \u003cli\u003eSteel construction holds shape under repeated use.\u003c\/li\u003e\n  \u003cli\u003eSingle-spring swaps provide measurable, reversible changes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich spring colors and strengths come in the kit?\u003c\/h3\u003e\n\u003cp\u003eThe 1464 kit contains one spring of each standard step-up strength used for tuning: 3 Hg (blue), 4 Hg (yellow), 5 Hg (orange), 7 Hg (pink), and 8 Hg (uncoated\/plain). These cover a useful range from lighter to heavier resistances so you can evaluate small and larger shifts in response.

The Edelbrock 1464 step-up spring pack is ideal for mechanics, restorers, and enthusiasts who tune carburetors or transmissions to achieve specific throttle or shift characteristics. If you frequently test different spring rates while dialing in performance or drivability, the plug-and-play kit saves time and reduces parts chasing. It’s also useful as a compact service spare for shops that perform tune-ups and rebuilds on vehicles with mechanical throttle or transmission linkages.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eProduct specifics:\u003c\/em\u003e Fit type is vehicle-specific — verify compatibility before purchase.
