NAPA Coil Spring Rear (NCS1729)

As one of the most central and dynamic components of a vehicle’s suspension system, coil springs from NAPA are rigorously tested as part of the manufacturing process to ensure driver safety and comfort as well as the lifespan of the vehicle.

All coil springs from NAPA undergo testing for durability including material testing to assess the strength of material used as well as the thickness of coating. They are also tested for load loss and fatigue through 200,000 cycles of cyclic fatigue testing, and corrosion resistance testing to show no rust during a 480 hour salt spray test, as well as final packaging checks to ensure product quality meets that of the exacting NAPA standards.
