Barrel Spring 12in x 2.5in x 250#

The SWIFT SPRINGS Barrel Spring 12in x 2.5in x 250# (MPN: 120-250-250 B) is a coil-over suspension spring engineered for vehicles requiring heavy-duty load support and precise damping control. This barrel-style coil spring delivers a 250 lb/in spring rate, making it suitable for applications where stability under load and consistent ride height are critical—from off-road recovery vehicles to performance suspension tuning on trucks and SUVs.

The spring measures 12 inches in length with a 2.5-inch inner diameter and is finished in black powder coat, providing corrosion resistance for both on-road and harsh outdoor environments. At 5 pounds per spring, this component integrates into coil-over suspension systems where precise spring rate matching is necessary to achieve proper suspension geometry and vehicle dynamics. The 250 lb/in rate strikes a balance between load-carrying capacity and ride compliance—stiff enough to prevent excessive compression under heavy payloads, yet compliant enough to absorb terrain impacts without harsh feedback.

This spring suits operators, mechanics, and vehicle builders who demand OEM-equivalent or aftermarket suspension performance. Whether upgrading a work truck, building a crawler, or tuning a coil-over system to match specific ride height and load requirements, the barrel spring design provides reliable, predictable performance. SWIFT SPRINGS manufacturing standards ensure consistent compression curves and durability across extended duty cycles.

Coil springs are load-bearing suspension components; proper matching with dampers (shocks) and installation within vehicle-approved weight limits is essential. Suspension modification may affect handling, braking, and ride comfort—consult manufacturer guidance or a qualified suspension technician before installation to ensure compatibility with your specific vehicle and intended use.
