Conventional Spring 16in x 5in x 175#

The Conventional Spring 16in x 5in x 175# from SWIFT SPRINGS is a purpose-built coil spring designed for chassis-level vehicle modifications and suspension tuning. This linear-rate spring is ideal for builders looking for precise load control in custom suspensions, lowering kits, or performance setups where consistent spring rate and predictable ride characteristics are essential.

With a spring rate of 175 pounds per inch, this spring provides controlled load response across its full length, optimized for compatibility with various vehicle platforms. The conventional (linear) design allows for proportional load increases with compression, enabling accurate suspension geometry calculations while avoiding the complexities of progressive springs. At a verified weight of 6.8 lbs, the spring's modest mass minimizes unsprung weight transfer, which is critical for maintaining tire contact patch consistency during dynamic driving conditions.

This spring is particularly beneficial for builders developing custom double-wishbone or MacPherson strut applications, ensuring that matched pairs perform identically for symmetrical suspension balance. SWIFT SPRINGS' manufacturing tolerances guarantee rate consistency across the production run, making this spring an excellent choice for both track-focused platforms and street-driven builds.
