Coilover Spring 2.5in ID 2.500in ID 150 Rate

The Coilover Spring 2.5in ID 150 Rate from DRACO RACING is engineered for drivers and fabricators building serious suspension systems where precision spring rates and consistent ride quality are non-negotiable. This linear-rate coilover spring sits at the heart of any adjustable suspension setup, delivering predictable performance whether you're tuning a track car, street machine, or competition platform. The 2.5-inch inside diameter and 150 lb/in spring rate make this component ideal for mid-weight vehicles requiring balanced compliance and support without excessive harshness.

At 3.8 lbs and measuring 5 x 4.9 x 16.1 inches, this spring integrates seamlessly into strut-based and coilover shock assemblies where a 150 lb/in rate provides the stiffness needed to control body roll and maintain consistent suspension geometry through corners while preserving enough compliance for real-world driving or rough track surfaces. The DRACO RACING specification ensures proper load-handling characteristics; a 150-rate spring resists compression progressively, keeping suspension travel predictable and minimizing unwanted deflection under lateral and vertical loads. Quality construction and tight manufacturing tolerances ensure consistent performance lap after lap and season after season.

This coilover spring benefits suspension builders and enthusiasts upgrading factory dampers to adjustable shock platforms or designing full custom setups for road racing, autocross, or drift applications. Proper pairing with a matching shock—tuned to complement the 150 lb/in rate—ensures optimal damping response and prevents premature spring fatigue or oscillation. Installation requires compatibility verification with your specific coilover kit or shock platform to confirm collar size and preload setup; consult your shock manufacturer's specifications before purchasing to guarantee proper fit and performance.
