Conventional Rear Spring 14in x 5in x 175lb

The Conventional Rear Spring 14in x 5in x 175lb from SWIFT SPRINGS is a precision coil spring engineered for heavy-duty suspension applications where consistent load support and durability are essential. Designed specifically for rear-axle mounting, this conventional spring delivers reliable performance in trucks, trailers, and utility vehicles that demand predictable spring rate characteristics. Whether you're building a custom suspension setup, restoring a classic vehicle, or maintaining fleet equipment, this 175 lb/in spring provides the controlled ride quality and load capacity that professional installers and serious enthusiasts depend on.

This conventional rear spring features a 5-inch outer diameter and 14-inch length, manufactured from high-grade steel with a durable black powder-coat finish that resists corrosion and extends service life in harsh road conditions. The 175 lb/in spring rate ensures smooth load distribution while maintaining structural integrity under repeated stress cycles—critical for vehicles regularly carrying heavy payloads or towing. The powder-coat application provides both aesthetic appeal and protection against rust, salt, and moisture exposure. At 6.2 pounds, the spring's weight is optimized for performance without adding unnecessary unsprung mass that could compromise ride dynamics.

This rear spring suits vehicle owners, restoration shops, and fleet maintenance technicians working with medium-duty applications requiring a moderate 175 lb/in rate. Installation is straightforward for experienced mechanics familiar with rear suspension geometry and spring mounting procedures. Verify compatibility with your vehicle's existing suspension architecture and axle design before ordering. The conventional design integrates seamlessly into classic and modern suspension systems alike, making it a versatile choice for custom builders and OEM replacement applications.
