Spring Conv. High Travel 9.5in x 5in x 550lb

The SWIFT SPRINGS Spring Conventional High Travel 9.5in x 5in x 550lb coil spring (MPN 950-500-550 F) is a heavy-duty front suspension component engineered for vehicles requiring high-travel capability and sustained load support. This conventional coil spring delivers a 550 lb/in spring rate in a 9.5-inch length with a 5-inch outer diameter, making it suitable for off-road platforms, lifted suspensions, and recovery-duty vehicles where extended articulation and consistent spring force are critical performance requirements.

The 550 lb/in spring rate balances responsiveness with load-carrying capacity, preventing bottoming-out under dynamic compression while maintaining ride compliance during normal operation. The high-travel design accommodates greater suspension stroke, essential for rough terrain, rock crawling, or vehicles carrying heavy payloads. The black powder-coat finish provides corrosion resistance in harsh environments, extending service life in salt air, mud, and wet conditions. At 6.15 lbs, this spring is manufactured from steel for durability and repeatable performance across temperature extremes and extended duty cycles.

This coil spring is specified for front axle applications on lifted trucks, expedition vehicles, and off-road platforms where factory suspension geometry has been modified for increased ground clearance or articulation. Users working in high-demand environments—overlanding, search and rescue, remote logistics, or competitive off-road racing—rely on quality suspension springs to manage rebound rates and maintain wheel contact during technical terrain. The high-travel specification ensures compatibility with extended suspension systems and provides the spring preload necessary for vehicles operating at or above their rated GVWR.

Conventional coil springs remain the industry standard for light to medium-duty suspension because they offer predictable load-deflection curves, easy replacement, and proven longevity in field conditions. When sourcing OEM or OEM-equivalent springs, verifying the spring rate, free length, and outer diameter against your vehicle's suspension specification sheet ensures correct fitment and optimal handling characteristics. The SWIFT SPRINGS brand is recognized in the aftermarket suspension sector for manufacturing to tight tolerances and delivering springs that maintain their rate specification over thousands of compression cycles.
