Rear Spring 5in ID 13in Tall

The Rear Spring 5in ID 13in Tall by HYPERCO is a precision coil spring engineered for custom vehicle suspension builds and performance upgrades. This component is essential for anyone modifying their vehicle's ride height, load capacity, or handling characteristics. Whether you're setting up a lowered sports car, adjusting spring rates for track work, or customizing a daily driver, selecting the correct spring dimensions and rates is critical to achieving proper geometry, tire wear, and overall vehicle dynamics.

Built with a 5-inch inner diameter and 14-inch overall height, this spring delivers consistent load support and deflection characteristics across its operating range. HYPERCO springs are manufactured to tight tolerances, ensuring consistent rate consistency and minimal coil-bind risk when paired with compatible dampers and suspension geometry. The 8.45-pound weight reflects the spring's steel composition and robust construction designed to handle repeated compression cycles without fatigue or permanent set, making it ideal for both street and motorsport applications requiring durability and predictable response.

This rear spring benefits chassis builders, suspension engineers, and enthusiasts performing complete suspension overhauls or spring-rate upgrades on performance vehicles. Proper installation requires verification of vehicle-specific spring perches, ride height targets, and complementary front spring rates to maintain balanced suspension tuning. With its reliable performance, this spring is a valuable addition to any custom suspension setup.
