Swift Springs 120-250-500V2 Barrel Progressive Spring 12in x 2.5in

The Swift Springs 120-250-500V2 is a high-performance barrel spring designed for progressive suspension tuning. This 12-inch length spring features a 2.5-inch diameter with progressive rate characteristics, making it ideal for racing and high-performance applications where variable spring rates are needed.

Key Features:

• Progressive spring rate design for improved handling and ride quality
• Barrel shape construction optimizes space utilization and weight distribution
• 12-inch free length with 2.5-inch outside diameter
• Manufactured from high-tensile strength spring steel
• Proprietary H.A.S.T. (High Advanced Spring Technology) material for superior durability
• Precision wound to exacting tolerances for consistent performance
• Shot-peened surface treatment for extended fatigue life

Swift Springs are engineered using advanced metallurgy and manufacturing processes to deliver linear response characteristics and exceptional resistance to sag and settling. The progressive rate design provides a softer initial spring rate for improved comfort and compliance, transitioning to a firmer rate under higher loads for better control and bottoming resistance.
