Synergy 2005+ Ford Super Duty 4x4 Leveling Springs

Our Synergy 2005+ Ford Super Duty 4x4 Leveling Springs are engineered from the ground up specifically for the Super Duty platform and designed to deliver improved ride quality, handling, and load support while achieving a true level stance. Unlike generic or repurposed springs, these coils are optimized for the weight, suspension geometry, and real-world demands of Ford’s heavy-duty trucks.

Featuring a true multi-rate design, these springs offer a compliant initial ride for everyday comfort, transitioning into a firmer rate to properly support added weight from bumpers, winches, plows, and work equipment—without sacrificing control. The increased free length ensures proper coil retention at full droop, making them ideal for trucks that see rough terrain, job sites, or extended suspension travel.

Engineered to deliver a 2.5” front lift, these springs level the factory rake while maintaining proper suspension function and drivability. Designed with real-world use in mind, they help keep your truck riding smooth and controlled whether it’s towing, hauling, or putting in long miles.

Manufactured in the USA from premium high-strength steel, Synergy springs are pre-set to resist sagging and built to handle full compression cycles without fatigue—providing long-term durability and performance you can rely on.
