Sierra 1500 2025-2026 GMC - Leaf Spring Top Plate Conversion by Cognito

The Cognito Leaf Spring Top Plate Conversion Kit (110-91316) is designed for 2025-up GMC Sierra 1500 trucks equipped with the updated factory rounded leaf spring top plate and U-bolt configuration.

Beginning in the 2025 model year, GM introduced a rounded top plate design that uses a different U-bolt style than previous generations. This change can create compatibility issues when installing lift or leveling kits that utilize traditional lift blocks and square-style GM U-bolts.

This conversion kit allows the rear suspension to be converted back to a flat top plate configuration, making it compatible with traditional GM square U-bolts used in many aftermarket lift and leveling kits. It provides a simple solution for properly installing suspension upgrades that include lift blocks and standard U-bolt hardware.

Engineered for proper fitment on the 2025-up GM 1500 platform, this kit ensures compatibility with common aftermarket suspension setups while maintaining a secure and reliable rear suspension mounting configuration.
