Conventional Spring 13in x 5in 125LB

The SWIFT SPRINGS Conventional Spring 13in x 5in 125LB is a precision-engineered coil spring designed for vehicles requiring precise ride height control and load support. This spring is ideal for builders looking to enhance their vehicle's suspension, whether for street performance or racing applications.

Built to SWIFT SPRINGS' exacting standards, this 13-inch spring features a linear rate curve that translates driver input directly to suspension response without binding or unpredictable behavior. The spring's 5.5-inch coil diameter and 125-pound spring constant provide a balance between stiffness for minimizing body squat under acceleration and compliance for street comfort when paired with appropriate damping.

This conventional design simplifies tuning suspension geometry and shock valving, making it a preferred choice for performance enthusiasts. With a weight of 4.7 lbs, the spring contributes to reduced unsprung mass, enhancing wheel response and overall vehicle dynamics.
