Product Overview
The ReadyLIFT 4" Big Lift Kit is engineered specifically for 2022–2025 Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4X 4WD trucks seeking improved ground clearance, aggressive lifted styling, and oversized tire fitment while retaining factory Multimatic DSSV suspension performance. Designed exclusively for GM’s premium off-road platforms, the system combines ReadyLIFT’s suspension geometry correction with the factory-installed 2-inch ZR2/AT4X lift to deliver approximately 6 inches of total lift height.
These premium lift systems are engineered specifically around the factory DSSV suspension package and include heavy-duty fabricated crossmembers, differential drop brackets, steering correction components, rear lift hardware, and skid plate protection designed to maintain OEM ride quality and steering characteristics. ReadyLIFT designed the system to preserve factory suspension functionality while improving tire clearance and overall off-road capability.
The system supports up to 35x12.50-inch tires on compatible wheel setups while maintaining daily drivability and premium ride comfort. Designed for both trail use and aggressive street presence, the ReadyLIFT 4" Big Lift Kit delivers improved capability without sacrificing factory refinement. Now Available at LEER!
