Conventional Spring 11in x 5in x 175#

The Conventional Spring 11in x 5in x 175# from SWIFT SPRINGS is a precision coil spring designed for custom suspension builds and vehicle modifications. This component is essential for mechanics and enthusiasts who demand consistent ride height, load capacity, and handling characteristics in lifted trucks, lowered street cars, or performance suspension systems.

At a free length of 11 inches and a coil diameter of 5 inches, this conventional coil spring offers balanced stiffness suitable for both street and mild performance applications. The 175 lbs/inch rating means the spring compresses one inch under 175 pounds of load—ideal for supporting moderate suspension modifications without harsh ride quality. Conventional springs like this unit maintain linear compression curves, making them predictable and easier to tune than progressive designs.

Weighing 3.65 pounds, the spring integrates seamlessly into OEM or aftermarket suspension assemblies, and its standardized dimensions ensure reliable fitment across a range of vehicle platforms commonly modified by serious builders. Mechanics and suspension technicians typically pair this spring with matching shocks, struts, and geometry kits to achieve target ride heights and handling balance. The 175 lbs/inch rate works well in both front and rear applications.
