2019-2024 GM 1500 6" MAX 3.3 Suspension System w/ Falcon 3.3 Adj Shocks (42-39640)

The ReadyLIFT 6-inch MAX3.3 Premium Suspension System for the 2019-2024 Chevy Silverado and GMC Sierra 1500 4WD is engineered for truck owners who refuse to compromise on performance. At its core are the Falcon 3.3 Fast Adjust Front Remote Reservoir Coilovers and Rear Piggyback Shocks, offering independent dual-knob tuning for precise damping control. This complete suspension upgrade utilizes heavy-duty DOM tubular steel upper control arms and boxed steel crossmembers to maintain factory ride quality and turning radius while providing the clearance needed for oversized tires and a commanding off-road presence.
