ReadyLIFT 6” Big Lift Kit (4” + 2”) – Chevrolet Silverado 1500 ZR2 / GMC Sierra 1500 AT4X (2025)

The ReadyLIFT Big Lift Kit (4” + 2”) is designed specifically for the Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4X (2025), combining the factory 2” lift with an extra 4” for a total lift of up to 6”.
