Barrel Spring 14in x 2.5in x 185#

The Barrel Spring 14in x 2.5in x 185# from SWIFT SPRINGS is a precision coil spring engineered for suspension tuning and performance vehicle modifications. This barrel spring is designed for enthusiasts and professional mechanics who demand consistent ride height, load support, and handling response across a wide range of driving conditions. Whether you're building a lowered street car, tuning a drift platform, or optimizing suspension geometry for track use, a properly specified spring rate is foundational to chassis performance.

The 185-pound spring rate defines how much force is required to compress this spring one inch, making it suitable for mid-weight vehicles or as a supplementary component in dual-spring setups. The 14-inch free length and 2.5-inch outer diameter accommodate most coilover kits and custom suspension fabrications, while the barrel design (progressive or linear, depending on winding) distributes load evenly and resists coil bind under compression. SWIFT SPRINGS' manufacturing maintains tight tolerances on rate accuracy, ensuring predictable spring behavior and eliminating the guesswork from suspension geometry calculations.

This spring excels in applications requiring moderate spring stiffness without excessive harshness—think street-performance sedans, lightweight coupes, or rear-axle support in independent suspension designs. Installation requires proper spring compressors and suspension knowledge; incorrect seating or pairing with incompatible dampers can compromise handling and safety. Always match spring rate to vehicle curb weight, intended use, and complementary damper valving for optimal suspension tuning and longevity.
