Cognito Front Shock Extender | 2024+ 2500HD AT4X/ZR2

Cognito Front Shock Extender Kit

For 2024–2025 GMC Sierra 2500HD AT4X / Chevrolet Silverado 2500HD ZR2

Unlock the full potential of your truck’s front suspension with the Cognito Front Shock Extender Kit. Designed specifically for 2024+ AT4X and ZR2 HD models equipped with Multimatic DSSV shocks, this precision-engineered billet aluminum spacer increases droop travel by over 50% — transforming ride quality and control both on and off-road.

In factory form, these trucks have just 2" of front droop travel, leading to a harsher ride over uneven terrain. Cognito’s testing determined the exact spacer thickness needed to safely extend droop to just over 3", resulting in noticeably smoother compliance through dips and bumps without bottoming out or topping out the shocks.

Features:

• Precision Billet Aluminum Construction
• Anodized Blue Finish to match factory DSSV shocks
• Precisely engineered to maximize droop travel
• Increases front suspension droop from 2" to just over 3"
• Improves ride comfort and suspension performance
• DIY-friendly 1-hour install time
• Made in the USA

Vehicle Fitment:

• 2024–2025 GMC Sierra 2500HD AT4X
• 2024–2025 Chevrolet Silverado 2500HD ZR2
