Conventional Spring 16in x 5in 150lb

The SWIFT SPRINGS Conventional Spring 16in x 5in 150lb (part number 160-500-150 BP) is a heavy-duty coil spring engineered for rear suspension applications requiring a 150 lb/in spring rate. This conventional spring delivers predictable load response across a wide range of operational conditions and is constructed from steel with a copper powder coat finish to resist corrosion and environmental degradation.

With a 16-inch length and 5-inch outer diameter, this spring offers a robust spring rate of 150 pounds per inch—a specification that determines how much load the spring can support before compressing one inch. The 150 lb/in rate makes this spring suitable for medium to heavy-duty load-bearing applications where controlled suspension travel and stability are priorities. The copper powder coat provides both aesthetic consistency and functional corrosion resistance, protecting the steel substrate in harsh environments including high-temperature or moisture-exposed settings.

This spring is designed for applications requiring consistent, repeatable performance under sustained load—such as heavy equipment suspension, vehicle lifting systems, industrial machinery, or off-road suspension upgrades. Buyers selecting a 150 lb/in spring rate prioritize stability and load capacity over compliance; this spring maintains its characteristics across extended duty cycles. The individual unit design allows for custom suspension configurations or as a direct replacement in matching systems.

Spring rate selection is critical to suspension performance. A 150 lb/in rate sits in the medium-to-stiff range, suitable for loaded vehicle platforms or equipment needing minimal deflection under working conditions. The SWIFT SPRINGS brand is recognized in the suspension and industrial springs market for straightforward, application-focused design without premium pricing.
