Conv Rear Spring 5in x 11in x 200

The Conv Rear Spring 5in x 11in x 200 from INTEGRA SHOCKS is a conventional coil spring engineered for rear suspension systems on vehicles requiring precise load support and controlled ride geometry. This 200 lb/in spring rate component is built for mechanics and automotive enthusiasts who demand reliability when restoring or modifying suspension systems. Conventional coil springs remain the industry standard for factory-style applications and upgrade builds, offering predictable performance characteristics and straightforward installation compared to air suspension or complex independent systems.

Manufactured from high-strength steel with a black powder coat finish, this rear spring features a 5-inch outer diameter and 11-inch free length, delivering consistent compression and extension cycles over thousands of load cycles. The 200 lb/in spring rate—a moderate stiffness specification—balances comfort for daily driving with enough resistance to handle payload increases, cargo, or passenger weight without excessive sag. The powder coat protects against corrosion and salt damage, critical for vehicles in harsh climates or regions with winter road treatment. Each spring is individually packaged and rated for safe, repeatable performance across multiple seasons.

This rear spring suits owners upgrading worn OEM suspension, building lifted trucks, or fine-tuning ride height and load capacity on trucks and SUVs. The 200 lb/in rate works best on vehicles in the mid-weight range where factory springs have fatigued or where modest load increases demand stiffer support without bottoming-out risk. Installation requires basic suspension knowledge and proper spring compressors for safe handling. Pair this rear spring with matching front components and shock absorbers from INTEGRA SHOCKS to achieve balanced, predictable suspension geometry and vehicle control.
