Bilstein B6 4600 Series Front Shock Absorber – 24-196437

Upgrade your heavy-duty Duramax with the Bilstein B6 4600 Series front shock absorber (part #24-196437). This direct-fit monotube gas-pressure shock is engineered specifically for stock-height 2011–2023 Silverado and Sierra 2500HD/3500HD trucks, delivering a noticeable improvement in ride quality, control, and durability over worn factory shocks.

Key Features & Benefits

• 46mm monotube gas-pressure design – Superior heat dissipation and consistent, fade-free damping even under heavy loads, towing, or repeated impacts
• Velocity-sensitive digressive valving – Instantly reacts to changing road conditions for a smooth, controlled ride on highway, gravel, or work sites
• Application-specific tuning – Optimized for stock-height GM ¾- and 1-ton trucks to reduce body roll, nose dive, and harshness while maintaining comfort
• Direct bolt-on installation – Uses factory mounting points (upper bar pin / lower clevis); no modifications required
• Durable construction – Yellow powder-coated finish with protective blue boot for corrosion resistance and long service life
• Limited lifetime warranty from Bilstein

Perfect For

Daily driving, towing trailers or goosenecks, hauling, and light off-road use. Ideal upgrade when replacing sagging or faded OE shocks on your Duramax without changing ride height.

Sold individually (two required for the front axle). Pair with matching rear Bilstein 4600 shocks for a complete balanced upgrade.

Fitment Notes
Compatible with 2011–2023 4WD Chevrolet Silverado 2500HD / 3500HD and GMC Sierra 2500HD / 3500HD (stock height suspension).
