Spring DLM RR -2 10in

The BILSTEIN Spring DLM RR -2 10in coil spring delivers precision damping and progressive spring rates for high-performance suspension tuning. Built with a 2.5-inch inner diameter, 10-inch length, and progressive coil design, this coil-over spring is engineered for applications requiring fine-tuned load control and responsive handling characteristics across varying road and track conditions.

Constructed from high-grade steel with blue powder-coat finish, the spring resists corrosion and UV degradation while maintaining structural integrity under continuous cycling. The progressive rate design allows the spring to operate with a softer initial rate for bump compliance, then stiffens as load increases—a characteristic valued in performance suspension for managing both comfort and control. The 2-inch coil bind specification ensures the spring reaches maximum compression without binding or coil separation. At 4.45 lbs, this component integrates seamlessly into dedicated coil-over systems where damper coordination and spring pairing are critical to suspension geometry and response.

This spring is suited for builders and suspension technicians who specify BILSTEIN components for dedicated race cars, drift platforms, track-focused street builds, and off-road recovery vehicles where suspension tuning requires precision hardware. The 10-inch length makes it compatible with coil-over systems designed around mid-travel strut or shock applications. Proper installation requires pairing with a complementary damper rated for the intended spring rate and load range to achieve the desired suspension behavior.

BILSTEIN's engineering reputation in motorsports and suspension development supports the precision specifications of this spring. Springs play a fundamental role in suspension tuning—they establish ride height, load carrying capacity, and the initial rate profile that a damper must control. Selecting the correct spring rate and length requires matching the component to both vehicle weight and suspension geometry, making accurate specification critical.
