The Firestone 6025 Coil-Rite air helper spring is engineered to enhance the ride quality and load-carrying capability of vehicles equipped with coil spring suspension systems. This replacement air spring fits inside your existing coil springs to create a variable spring rate, allowing you to adjust support based on your current load and driving conditions.

Key Features:

• Dimensions: 4 inches x 11 inches, designed to fit within factory coil springs
• Load capacity: Supports 500-1,000 lbs. per set (not to exceed vehicle GVWR)
