Barrel Spring 12in x 2.5in x 400#

The SWIFT SPRINGS Barrel Spring 12in x 2.5in x 400# (Part Number 120-250-400 B) is a coil-over barrel spring designed for suspension tuning, vehicle recovery systems, and custom suspension builds. This spring is ideal for operators, mechanics, and vehicle builders who require reliable spring performance in demanding conditions.

With a spring rate of 400 pounds-per-inch, a free length of 12 inches, and an inner diameter of 2.5 inches, this spring provides the load support and predictable deflection characteristics necessary for heavy-duty applications. Constructed from hardened steel and finished with a black powder coat, it resists rust and corrosion, making it suitable for off-road recovery work and extended outdoor deployment.

This barrel spring is particularly beneficial for vehicles carrying sustained loads or requiring quick response under dynamic conditions. It is essential for ensuring even load distribution across axles or suspension points, especially in matched-pair or multi-spring configurations. The SWIFT SPRINGS brand is known for precision manufacturing, where tolerances are critical to chassis geometry and ride quality.
