NAPA Coil Spring

We Know Quality

Coil springs are routinely exposed to weathering elements due to their open fitting positions and their role in absorbing shocks. The importance of installing springs capable of enduring against exposure can make or break a suspension system. NAPA Coil Springs are designed and tested to provide only the best performance for a range of parts that stay stronger longer.

We Know Our Products

NAPA Coil Springs are part of a market-wide expansion of coil spring products across the automotive aftermarket. Where our springs distinguish themselves is through a comprehensive production process that locks in quality right out of the box.

The Complete Coil

At NAPA, we manufacture our coil springs using mechanical innovations and materials specifically chosen for durability. In addition to being shot-peened for added fatigue strength, we enhance our coils with constant wire and cold coiling technology for superior structural reliability. Parallel and tapered wire construction processes pair with surface strengthening coating for a fit that is as tailored to your vehicle application as it is to resisting harsh environmental conditions.

Quality Assured

Produced in a cutting-edge facility that consistently adheres to the exacting standards of the automotive industry, NAPA Coil Springs are subject to production and testing procedures that ensure no part falls short of excellence. In addition to general end-of-line evaluation, our coil springs must pass:

  • Durability and material testing to verify the thickness of the coating, load loss and fatigue through 300,000 cycles of cyclic fatigue testing.
  • Corrosion resistance testing via 480 hours of salt spraying to ensure rust does not form.
  • Packaging checks to meet NAPA standards of product quality and presentation.

NAPA Coil Springs are only dispatched from our ISO-accredited production facility after meeting the criteria laid out by these tests. Adhering to this practice ensure that every coil spring we produce guarantees superior performance with every purchase.

We Know How

At NAPA, Know How is everything. Coil springs may be built to withstand pressure, but we like to lessen the load where we can. All our coil springs are supported by a 3 year/36,000-mile warranty, which protects you in the unlikely event of a faulty product.

Our team of technical experts are on hand to provide support and guidance on our range of coil spring products. This can cover anything from installation best practices to regular content releases addressing frequently asked questions regarding our other product ranges. Quality may begin with the product, but there is never an end to our Know How.
