ReadyLIFT Suspension 44-39420 4-Inch Lift Kit for GM 1500 Trail Boss and AT4

The ReadyLIFT Suspension 44-39420 4-Inch Lift Kit is designed for select GM 1500 Trail Boss and AT4 applications, providing increased ground clearance and a more aggressive stance while maintaining practical on-road drivability. This suspension lift solution is engineered for enthusiasts who want improved off-road capability without relying on a body lift or an overly complex suspension conversion.

ReadyLIFT Suspension components are developed to work with the factory suspension architecture and support proper vehicle geometry when installed as directed. The kit is suitable for improving approach, breakover, and departure clearance, while also creating room for larger tires on compatible configurations. Final tire, wheel, and clearance compatibility should be verified before installation, particularly on vehicles with aftermarket wheels, tires, or suspension components.
