Coilover Spring 1.875in ID 10in Tall 175lb

The Coilover Spring 1.875in ID 10in Tall 175lb from DRACO RACING is a precision suspension component engineered for builders and enthusiasts pursuing full-control coilover setups on street, track, or show vehicles. This individual spring serves as a critical element in custom suspension geometry, allowing you to dial in ride height, spring rate, and load distribution independently of your damper choice. Whether you're upgrading a street car for aggressive stance work or building a competition platform, this coilover spring provides the foundation for repeatable, tunable suspension performance that far exceeds OEM capability.

At 175 pounds per inch (lbs/in), this spring rate suits vehicles in the 2,800–3,500 lb range, making it ideal for compact coupes, lightweight sports cars, and mid-sized platforms where progressive handling and minimal body roll are priorities. The 1.875-inch inner diameter (ID) and 10-inch free length are precision-manufactured to DRACO RACING's strict tolerances, ensuring consistency across multiple installations and allowing seamless integration with aftermarket coilover bodies that accept this specification. The spring's 2.15 lb weight keeps unsprung mass minimal, a critical advantage in performance applications where reduced rotational inertia directly improves acceleration, braking response, and cornering dynamics. Linear spring design delivers predictable load curves, eliminating the unpredictability that can arise from progressive or digressive rates in street-driven cars.

Mechanics and suspension builders typically specify this coilover spring when constructing complete independent coilover kits for non-OEM applications or when rebuilding aged systems requiring spring replacement. Verify your coilover body's ID specification and desired ride frequency (typically 2.0–3.0 Hz for street cars) before ordering; this spring works best paired with a compatible shock absorber featuring matching mounting eyes and length. Installation requires proper spring compression tools and professional alignment adjustment post-setup. This component is not a direct bolt-in replacement for OEM springs but rather a core building block for complete custom suspension architectures where control and adjustability outweigh plug-and-play convenience.
