Coilover Spring 10in x 2.5in x 350lb

The Coilover Spring 10in x 2.5in x 350lb (SKU: SWI100-250-350B) is a heavy-duty suspension component engineered for tactical vehicles, off-road platforms, and precision firearm builds requiring adjustable load support. Designed for professionals in law enforcement, military, and civilian tactical operations, this coil-over spring provides the tunable suspension geometry necessary for vehicles operating in demanding terrain or carrying substantial tactical loads. The 350-pound-per-inch spring rate delivers predictable, controlled compression across the full stroke, making it ideal for platforms where both performance and reliability are non-negotiable.

This coilover features a 10-inch overall length with a 2.5-inch inside diameter barrel, constructed from high-strength steel and finished in durable black powder coat to resist corrosion and operational wear. The 350lb/in spring rate is precisely calibrated to manage vertical load transfer while maintaining chassis control during dynamic movement—critical when vehicles are loaded with tactical gear, communications equipment, or emergency response systems. The barrel design integrates seamlessly with standard coilover shock assemblies, allowing for field-adjustable ride height and damping characteristics without requiring suspension geometry modifications or secondary components.

Field operators and fleet managers benefit most from this spring's modularity and performance consistency in high-stress environments where suspension failure is operationally unacceptable. The 350lb/in rate suits mid-to-heavy duty applications—from armored personnel carriers and tactical support vehicles to precision precision rifle platforms requiring vibration isolation and repeatable zero retention. Installation pairs directly with compatible coilover shock bodies; verify mounting diameter and shock length before procurement. At 4.25 lbs per unit, weight remains minimal relative to load capacity, making this spring suitable for weight-sensitive platforms without sacrificing structural integrity or dynamic response.
