Cognito 2.5" Standard Lift Kit

 

The Cognito 2.5" Standard Lift Kit is designed specifically for 2024+ Silverado and Sierra 2500HD AT4X and ZR2 models, addressing factory suspension limitations while delivering a true lift and improved performance. It delivers increased ride height while correcting geometry issues introduced by the factory “leveling-style” setup.

Built from heavy-duty components engineered in the USA, this system offers durability and long-term reliability. The design focuses on restoring proper suspension function by increasing droop travel and maintaining correct CV axle angles, making it ideal for off-road use, towing, and everyday driving.

Additional features include a front subframe, taller steering knuckles, differential drop brackets, and billet shock clevis mounts. These components work together to eliminate front-end top-out issues and improve ride quality over uneven terrain.

Engineered with vehicle-specific fitment, it integrates seamlessly with AT4X and ZR2 factory suspension systems while retaining OEM Multimatic DSSV shocks for cost-effective performance.

Installation is typically a bolt-on process with no major cutting required, though moderate to advanced mechanical experience is recommended due to suspension component replacement.

Whether you're upgrading for improved off-road capability, larger tire fitment, or correcting factory suspension limitations, this product delivers a well-balanced lift solution. Now Available at LEER!
