Coilover Spring 7in x 2.5in 550LB Barrel

The SWIFT SPRINGS Coilover Spring 7in x 2.5in 550LB Barrel is a precision suspension component engineered for vehicles requiring responsive, tunable spring rate performance. This coil-over barrel spring delivers 550 lb/in spring rate across a 7-inch compressed length with a 2.5-inch inner diameter, making it suitable for off-road suspension systems, performance vehicle builds, and tactical mobility platforms that demand predictable load management and consistent ride height control.

Built from high-grade steel with a durable black powder coat finish, this spring resists corrosion and abrasion in harsh field environments. The 550-pound spring rate strikes a balance between supporting moderate payload without excessive preload, while the 2.5-inch bore diameter ensures compatibility with standard coilover shock bodies. At 3.84 lbs per unit, the spring weight remains manageable for installation and adjustment purposes. The barrel-wound design provides consistent force delivery throughout the compression cycle, critical for maintaining vehicle stability during load shifts or uneven terrain.

This coilover spring suits operators and enthusiasts building or upgrading suspension systems for trucks, tactical vehicles, and off-road platforms where spring rate precision matters. Whether tuning a patrol vehicle suspension, constructing an overland rig, or fine-tuning track performance, buyers need springs with exact specifications to match their shock architecture and weight distribution. The SWIFT SPRINGS barrel spring provides the repeatability and structural integrity required for these applications, with the 550-pound rating offering moderate support suitable for mid-weight vehicle configurations.

Coilover springs are sold individually, and correct spring rate selection depends on total vehicle weight, suspension geometry, and desired ride characteristics. Buyers should verify that the 550 lb/in rate matches their platform's requirements before installation. The black powder coat provides rust protection suitable for wet or salt-air environments where corrosion risk is elevated during extended field operations or coastal deployment.
