Barrel Spring 12in x 2.5in x 225#

The SWIFT SPRINGS Barrel Spring 12in x 2.5in x 225# is a heavy-duty coil-over suspension spring engineered for demanding off-road and recovery applications where consistent load support and precise rate control are critical. With a 225 lb/in spring rate, 12-inch length, and 2.5-inch inner diameter, this barrel spring delivers the predictable compression and rebound characteristics required in custom suspension builds, winch recovery platforms, and specialized vehicle modifications.

The 225-pound-per-inch rate positions this spring in the firm-to-stiff range, making it suitable for vehicles carrying heavy payloads, towing equipment, or deployed gear. The barrel design—with its varying coil diameter—distributes load more progressively than linear coils, reducing bottoming-out risk under compression spikes and extending suspension cycle life. Black powder coat finish provides corrosion resistance in harsh environments, from coastal salt-air exposure to desert dust and mud. At 4.6 lbs and measuring 4.7 x 4.7 x 15.3 inches, the spring integrates into compact coil-over assemblies without excessive weight penalty.

This spring is specified by suspension technicians, off-road builders, and vehicle recovery specialists who require a single unit (sold individually) that can be paired with compatible shock absorbers and mounting hardware. The 2.5-inch ID accommodates standard coil-over shock bodies, making this spring a direct replacement or upgrade component in established suspension systems. Whether supporting auxiliary battery systems on expedition rigs, reinforcing load capacity on duty vehicles, or tuning ride rate on competition platforms, the SWIFT SPRINGS barrel spring delivers the rate consistency and durability operators depend on.
