Spring DLM 12in 125 lbs

The BILSTEIN Spring DLM 12in 125 lbs coil spring is a precision-engineered suspension component designed for coil-over applications where consistent spring rate and reliable performance are essential. With a 125 lb/in spring rate, 2.5-inch inner diameter, and 12-inch free length, this steel coil spring delivers the predictable load characteristics needed in performance suspension systems, off-road recovery setups, and custom suspension tuning. The blue powder coat finish provides corrosion resistance in harsh environments while maintaining the spring's structural integrity under repeated cycling.

The 125 lb/in rate means this spring compresses one inch under 125 pounds of force—a moderate spring rate suited for applications requiring balanced compliance and support without excessive stiffness. The 2.5-inch ID accommodates standard monotube shock absorbers and allows for precise vertical load management in coil-over setups. At 12 inches long, this spring fits into compact suspension designs while providing adequate extension range. Steel construction ensures durability through thousands of compression cycles, and the powder-coat finish resists oxidation in salt spray, mud, and high-moisture environments common in field recovery, off-road, and coastal operations.

This spring serves technicians and operators building or servicing custom suspensions, vehicle recovery systems, and performance platforms where OEM springs fall short of load or compliance requirements. BILSTEIN's engineering standards ensure consistent spring rate across the product's service life—critical for maintaining predictable suspension response during high-stress operations. Buyers should verify coil-over compatibility with shock body diameter and overall system ride-height geometry before installation to ensure proper fitment and performance.

Spring rate selection is application-specific: lighter rates provide comfort and compliance, while heavier rates increase support under load. The 125 lb/in specification positions this spring in the mid-range, making it versatile across light-duty recovery vehicles, off-road platforms, and custom suspension builds where weight and load are moderate. Pairing the correct spring rate with matching shocks and geometry ensures proper suspension kinematics and vehicle stability.
