Coilover Spring 10in x 2.5in x 425lb

The SWIFT SPRINGS Coilover Spring 10in x 2.5in x 425lb is a precision-engineered suspension component built for vehicles requiring reliable, consistent spring rates in high-demand applications. Designed for tactical and military operators who depend on stable platform geometry, this coil-over spring delivers the progressive load handling necessary for off-road performance, law enforcement vehicle modifications, and specialized transport platforms. Whether upgrading a duty vehicle's suspension or fine-tuning a tactical platform, this 425-pound-per-inch spring rate provides measurable improvements in ride quality and load distribution under operational conditions.

Manufactured from hardened steel with a black powder-coat finish, the coilover spring resists corrosion and maintains structural integrity in harsh field environments where exposure to moisture, salt spray, and extreme temperatures is routine. The 2.5-inch inner diameter and 10-inch barrel length are standard coil-over dimensions, allowing drop-in compatibility with most aftermarket suspension kits and OEM setups designed for medium-duty vehicle platforms. At 4.95 pounds per unit, this spring maintains a balanced weight profile while the 425-pound spring rate—neither too stiff nor too soft—enables operators to maintain vehicle control without sacrificing occupant comfort during extended patrol or transport operations. The black powder coat ensures longevity in corrosive environments while providing a professional, uniform appearance.

Law enforcement fleet managers, tactical vehicle builders, and military logistics personnel benefit most from this spring's predictable performance and durability standards. Installation requires removal of the existing coil-over assembly and proper alignment of the new spring within the shock body or suspension tube—a straightforward procedure for technicians familiar with suspension work. Always verify compatibility with your specific vehicle platform and existing shock absorber specifications before ordering; spring rate selection directly impacts handling characteristics and load-carrying capacity. Sold individually; most applications require a complete set of four springs for balanced suspension geometry.
