PROGRESSIVE SUSPENSION 413 Series Shock - Black - Standard - 15" 413-4039B

If you're running stock shocks, you're leaving performance on the table. The Progressive Suspension 413 Series delivers the extended travel and damping control that separates competitive setups from compromised ones. Whether you're chasing lap times or demanding reliability on the street, these shocks provide the fade-resistant performance and stability you need when it matters most.

Progressive engineered these specifically for high-performance applications where stock geometry and damping simply don't cut it. The extended length increases your available wheel travel and ground clearance, giving you more room to work with geometry tuning without sacrificing ride quality or introducing unwanted deflection under load.
