Spring DLM 8in 550 lbs

The Spring DLM 8in 550 lbs from BILSTEIN is a precision coil-over suspension component engineered for enthusiasts and mechanics seeking refined ride quality and handling control. This 8-inch progressive spring is designed to work in conjunction with performance shocks and struts, providing progressive spring rates that increase as compression deepens. Whether you're building a lowered street car, fine-tuning a weekend track warrior, or restoring a vehicle's suspension geometry after years of wear, this BILSTEIN spring delivers the consistent support and durability that separates professional-grade upgrades from basic bolt-on parts.

BILSTEIN's DLM (Dynamic Light Metal) spring technology uses high-quality steel with precise coil geometry to achieve a spring rate of 550 lbs/inch—a stiff enough rating for performance driving without sacrificing street manners entirely. The 8-inch length accommodates mid-travel suspension architectures common in modern platform applications, and the progressive winding delivers initial softness for bump absorption while ramping up support under load. At 4.4 lbs, this spring minimizes unsprung mass, reducing tire bounce and improving brake balance.

This spring excels in suspension overhauls where matching spring rates to shock valving is critical, making it an ideal choice for performance, street, and track applications. The 4.7 x 4.6 x 15.9 inch dimensions ensure compatibility with standard coil-over sleeves and dampers; the tight manufacturing tolerances BILSTEIN maintains prevent coil bind and premature fatigue. Upgrade your vehicle's suspension with this high-performance spring for enhanced handling and ride quality.
