The Belltech coil spring set for C‑10 pickup and Blazer (1963–1987) is engineered to lower truck ride height by roughly 1–3 inches while improving handling with sport‑tuned rates. These application‑specific springs are cold‑wound from chromium alloy steel, shot‑peened and powder‑coated gunmetal for corrosion resistance. They install as a direct replacement using OEM hardware and are backed by Belltech's lifetime warranty where applicable.
