Conventional Spring 16in x 5in 80lb Bullet Proof

The SWIFT SPRINGS Conventional Spring 16in x 5in 80lb Bullet Proof rear suspension spring is engineered for heavy-duty applications requiring precise load management and consistent ride control. This 80 pound-per-inch spring rate component delivers the predictable compression characteristics necessary for vehicles operating under sustained load, from commercial fleet operations to tactical vehicle setups where suspension performance directly impacts payload capacity and handling stability.

With a 16-inch length and 5-inch outer diameter, this conventional coil spring is designed to fit standard rear suspension mounting points on compatible platforms. The copper powder coat finish provides corrosion resistance in harsh environments—essential for vehicles exposed to salt spray, high humidity, or aggressive chemical road treatments. The 80 lb/in spring rate positions this component in the medium-duty range, suitable for applications balancing payload support with ride comfort on varied terrain. Each spring is manufactured to consistent specifications to ensure paired performance when replacing suspension components.

This SWIFT SPRINGS model serves fleet managers, vehicle maintenance specialists, and owners of trucks or utility vehicles requiring replacement or upgrade suspension components. The bulletproof designation indicates enhanced durability and impact resistance, relevant for vehicles operating in demanding conditions. Buyers should verify fitment against their vehicle's make, model, and year before purchase, as suspension geometry varies significantly across platforms.

Conventional coil springs remain the standard for rear suspension across most truck and SUV platforms due to their reliability, predictable behavior, and cost-effectiveness. The 80 lb/in rate is common in medium-duty applications; stiffer rates (100+ lb/in) target heavier payloads, while softer springs (60–70 lb/in) prioritize ride compliance. Proper installation requires appropriate suspension tools and may necessitate alignment verification after replacement.
