Spring 9.5in x 5in x 400 Platinum Front

The Eibach Spring 9.5in x 5in x 400 Platinum Front coil spring is engineered for drivers and mechanics seeking a reliable suspension upgrade that maintains factory ride quality while improving handling characteristics. As a front coil spring designed for conventional suspension systems, this component is ideal for street-driven vehicles and light track duty where consistent performance and durability matter. Eibach's Platinum Series represents a proven middle ground between OEM springs and aggressive lowering applications, making it a go-to choice for suspension tuning without sacrificing comfort or longevity.

Built from high-quality steel and protected with Eibach's proprietary platinum powder coat finish, this spring resists corrosion and maintains its structural integrity through harsh weather and road salt exposure. The 400 lb/in spring rate defines the spring's stiffness—the force required to compress it one inch—translating to a stiffer response than most factory springs without the harshness of competition-grade setups. At 9.5 inches in length with a 5-inch outer diameter, this front spring fits within conventional suspension geometry and works seamlessly with factory dampers, control arms, and mounting points. The robust construction and precision engineering ensure consistent spring rate across the product's lifespan, preventing rate sag that degrades handling over time.

This spring benefits owners upgrading from worn OEM springs, mechanics building handling-focused street cars, and enthusiasts pairing it with performance shocks for a coordinated suspension tune. Installation requires standard spring compressor tools and basic mechanical knowledge; a professional alignment following installation ensures optimal tire wear and steering response. Because springs are sold individually, a complete front suspension upgrade requires purchasing a pair—one for each side—to maintain balanced handling and prevent uneven weight distribution that compromises safety and tire life.
