Conventional Spring 13in x 5in 275LB

The SWIFT SPRINGS Conventional Spring 13in x 5in 275LB (SKU: SWI130-500-275) is a precision coil spring engineered for demanding mechanical and suspension applications. This conventional helical spring delivers a spring rate of 275 pounds per inch, making it suitable for load-bearing, vibration isolation, and dynamic force management in equipment ranging from industrial machinery to automotive suspensions and tactical gear systems. The 13-inch length and 5-inch outer diameter provide optimal geometry for mid-to-heavy-duty applications where consistent force return and durability are non-negotiable.

Constructed from high-grade steel with a black powder coat finish, this spring resists corrosion and surface degradation in field environments. The 275 lb/in spring rate indicates moderate stiffness—stiffer than light-duty springs but more compliant than heavy industrial designs—making it a versatile choice for applications requiring balanced deflection and load capacity. At 7.04 lbs, the spring maintains structural integrity under repeated cycling while remaining manageable for installation and replacement. The powder coat protects against rust in humid conditions and extends the operational lifespan of the assembly.

This spring suits mechanical engineers, equipment manufacturers, restoration specialists, and field operators who need reliable force control in suspension systems, shock absorption rigs, and load-distribution mechanisms. Whether supporting vehicle suspension geometry, managing recoil in mechanical platforms, or providing consistent tension in industrial assemblies, the 275-pound spring rate offers the performance sweet spot between responsiveness and durability. Users in tactical, automotive, and manufacturing sectors rely on conventional springs like this one for their predictable performance and proven long-term reliability across temperature and load variations.
