Rear Spring 5in ID 16in Tall

The Rear Spring 5in ID 16in Tall by HYPERCO is engineered for serious automotive builders and mechanics seeking precision suspension tuning on high-performance or modified vehicles. This coil spring represents the engineering standard for custom suspension setups where exact spring rate and ride height control are non-negotiable. Whether you're building a track-focused machine, upgrading a lifted truck, or fine-tuning a street performance build, this rear spring delivers the consistent load support and predictable deflection that separates professional-grade suspension from compromised systems.

HYPERCO springs are manufactured using high-quality spring steel and precision winding technology to achieve consistent spring rates across the full compression range. The 5-inch inner diameter and 16-inch tall design provide optimal packaging for rear suspension applications on mid-size to full-size performance vehicles, allowing proper mounting geometry and wheel travel clearance. At 5.09 lbs, this spring offers a lightweight solution without sacrificing durability, critical for vehicles where unsprung weight reduction translates directly to improved handling and reduced chassis articulation time during dynamic driving events.

This rear spring suits mechanics and enthusiasts upgrading independent or multi-link rear suspensions, particularly those building custom lowered setups, performance handling packages, or off-road capable vehicles requiring precise load distribution. Installation pairs best with complementary dampers, bushings, and anti-roll bar adjustments to optimize the complete suspension envelope. Confirm vehicle-specific mounting compatibility and spring rate requirements before ordering, as proper spring selection depends on total vehicle weight, load distribution, and intended driving application.
