The Conventional Spring 16in x 5in x 200# is a heavy-duty coil spring engineered for rear suspension applications requiring precise load control and consistent deflection characteristics. With a 200 pounds-per-inch spring rate and 16-inch length, this component delivers the stiffness needed for vehicles carrying payload or operating under demanding terrain conditions. The black powder-coat finish provides corrosion resistance in harsh environments, making it suitable for off-road platforms, utility vehicles, and tactical transport systems.
Key specifications define this spring's real-world performance. The 5-inch outer diameter (OD) determines mounting compatibility and clearance envelope, while the 200 lb/in rate controls how much the suspension compresses under load—critical for maintaining ride height and handling predictability when carrying gear, ammunition, or personnel. The 16-inch working length balances extended travel capability with compact installation in confined rear suspension bays. Steel construction with powder coating ensures long-term durability against salt spray, mud, and temperature cycling. At 8.59 pounds, the spring's weight contributes minimally to unsprung mass, preserving suspension responsiveness.
This rear spring addresses the needs of vehicle operators and technicians upgrading or restoring suspension systems on trucks, trailers, and off-road equipment. Users managing payload-heavy operations—whether hauling recovery gear, tactical equipment, or field supplies—depend on correctly-rated springs to maintain proper ride height and prevent bottoming under compression. The 200 lb/in rate positions this spring in the medium-heavy range, suitable for vehicles requiring enhanced load support without excessive stiffness that would degrade comfort on unimproved terrain.
Conventional coil springs remain the industry standard for rear suspension because of their reliability, predictable performance curve, and ease of replacement. Unlike air suspensions or complex multi-link systems, a conventional spring isolates its function—supporting load and controlling deflection—without integrated electronic components. This makes it ideal for tactical vehicles, work trucks, and systems prioritizing field-serviceability and minimal maintenance overhead.
