Spring DLM 14in 125 lbs

The Spring DLM 14in 125 lbs by BILSTEIN is a precision coil-over suspension spring engineered for custom automotive builds and performance suspension setups. This is the component serious mechanics and enthusiasts turn to when upgrading ride height, load capacity, or overall chassis dynamics on modified vehicles. Whether you're building a lowered street car, preparing a track vehicle, or fine-tuning an off-road rig, this spring delivers the consistent force required for predictable handling and proper weight distribution across the vehicle's contact patches.

Manufactured from high-grade steel and finished in durable blue powder coat, the Spring DLM 14in 125 lbs features a 2.5-inch inner diameter and delivers a spring rate of 125 pounds per inch (lb/in). This rate determines how much the spring compresses under load—critical data for matching suspension geometry, bump stops, and damper tuning. The 14-inch length and mid-range spring rate make this coil suitable for applications requiring moderate suspension stiffness without sacrificing ride quality on varied terrain. The powder-coated finish protects against corrosion and provides visual continuity with modern coil-over systems, while the standardized 2.5-inch bore ensures compatibility with most aftermarket adjustable coil-over platforms and shock bodies.

This spring suits builders working with BILSTEIN or equivalent coil-over damper kits, as well as those upgrading OEM suspension with performance-grade springs. Proper installation requires attention to ride height geometry, preload adjustment, and overall vehicle balance—factors that affect camber, toe, and anti-roll behavior. Verify 2.5-inch bore compatibility and confirm that your coil-over platform accommodates the 14-inch compressed and extended heights before purchase. Paired with quality dampers and matched spring rates front and rear, the Spring DLM 14in 125 lbs provides the foundation for responsive, repeatable suspension performance on street or competition duty.
