Conventional Spring 11in x 5in x 250#

The Conventional Spring 11in x 5in x 250# by SWIFT SPRINGS is a high-performance coil spring engineered for suspension tuning and custom vehicle modifications. Designed for automotive enthusiasts and professional builders, this spring delivers progressive load characteristics ideal for street performance, off-road applications, and custom suspension builds. Whether you're upgrading a daily driver or building a competition machine, understanding spring rate and geometry is critical to achieving the handling balance and ride quality your project demands.

At 250 pounds per inch rate, this conventional spring provides moderate stiffness suitable for vehicles running stock or mildly upgraded weight. The 11-inch free length and 5-inch outer diameter are core geometry specifications that determine how the spring packages in your suspension tower and controls wheel movement through compression and droop cycles. Swift Springs' manufacturing precision ensures consistent load curves across the entire travel range, preventing binding and maintaining predictable handling characteristics even under aggressive driving conditions. The 5.2-pound weight per spring minimizes unsprung mass, contributing to improved suspension response and reduced wear on dampers and bushings during dynamic cornering and braking events.

This spring works best in front or rear independent suspension setups where load distribution is relatively balanced and vertical articulation is moderate. Buyers should verify ride height, load capacity, and existing spring rate before installation to ensure the 250# rate complements their vehicle's weight, intended use, and damper tuning. Installation typically requires spring compressors, proper alignment, and verification of suspension geometry post-installation. Pair this conventional spring with quality dampers, modern bushings, and a complete suspension audit for optimal performance and longevity.
