Spring Conv Rear 12in x 5in 275lb

The SWIFT SPRINGS Spring Conv Rear 12in x 5in 275lb coil spring is a conventional-design helical spring engineered for suspension systems requiring precise load support and consistent deflection characteristics. With a 12-inch length, 5-inch outer diameter, and 275 lb/in spring rate, this component delivers predictable compression under load across a wide range of vehicle and equipment applications. The black powder-coat finish provides baseline corrosion resistance, making it suitable for both on-road and off-road environments where durability against environmental exposure is essential.

The 275 lb/in spring rate defines how much force is required to compress the spring one inch—a moderate rate that balances load capacity with ride compliance. This specification matters in real-world application: a heavier spring rate maintains ride height under load but increases suspension stiffness, while a lighter rate absorbs bumps more softly. At 5 inches OD and 12 inches in overall length, this conventional coil design fits standard suspension packages found in light-duty to mid-range applications. The individual spring weighs 6 lbs and ships as a single unit, allowing buyers to replace one spring or upgrade matching pairs as needed.

This spring is ideal for owners and technicians managing suspension maintenance on trucks, trailers, industrial equipment, and recovery vehicles where stock or aged springs require replacement. Conventional coil springs remain the industry standard for cost-effective, reliable load support—they are easier to source than progressive-rate alternatives and work seamlessly with existing mounting hardware. Whether addressing sagging suspension, preparing a vehicle for heavier payload, or performing routine maintenance, the 275 lb/in rate provides a versatile middle ground suitable for many light-duty applications.

SKU SWI120-500-275 identifies this specific model from SWIFT SPRINGS' product line. When shopping for replacement springs, verifying outer diameter, length, and spring rate against your vehicle's factory or modified suspension design ensures proper fit and performance. TacticalSurplusUSA stocks this single spring for customers requiring individual replacement units or who prefer to source components separately for custom builds.
