Conventional Spring 9.5in x 5in x 500#

The Conventional Spring 9.5in x 5in x 500# from Swift Springs is designed for builders and mechanics who require dependable suspension tuning in performance applications. This coil spring is ideal for lowering kits, custom chassis builds, and replacement scenarios where stock spring rates may not adequately support upgraded components or increased vehicle weight. Whether upgrading a track car, modifying a street machine, or restoring a classic vehicle, this high-quality conventional spring rated at 500 pounds per inch provides consistent load support and predictable wheel articulation.

The spring features a conventional design with traditional helical coil construction optimized for linear spring rates. This design helps eliminate bind-up and ensures smooth compression and rebound cycles throughout the full travel range. With a free length of 9.5 inches and a barrel diameter of 5 inches, this spring is a mid-range option suitable for double-adjustable shocks or OEM-style dampers, providing firm support without compromising ride quality.

Mechanics and fabricators will find this spring most beneficial when matched with properly valved dampers and complementary anti-roll bars to achieve balanced front-to-rear load transfer. Its weight of 6.33 lbs and compact dimensions of 6 x 5.9 x 12.3 inches facilitate straightforward packaging in most coilover systems and custom suspension frames, making installation and tuning accessible to experienced builders.
