4" 2019-2026 GMC Sierra 1500 AT4 4WD Fox Performance Elite Coilover Lift Kit by BDS Suspension

The BDS Suspension BDS1805FPE/BDS1807FPE 4-inch premium lift kit for the GMC Sierra 1500 AT4 truck is an excellent suspension upgrade that not only allows for the use of up to 37-inch tires but also significantly improves ride quality and suspension performance. Featuring Fox 2.5 Performance Elite Series Coilovers, engineered to outperform on and off-road as they soak up any terrain thrown at them. These coilovers are equipped with DSC (Dual Speed Compression) adjustment technology. DSC allows for easy adjustment of the vehicle's suspension compression damping so you can dial in the perfect ride performance. The DSC features 12 adjustment points for high-speed compression, as well as 10 adjustment points for low-speed compression, allowing you to make large or small adjustments to further enhance performance. Adjustments can be made by simply twisting the knobs located on the end of the reservoir; no tools or shop adjustments needed, perfect for the trail!

Complementing the Fox Coilovers, BDS utilizes a pair of specially designed 1/4" thick laser cut high clearance crossmembers to maximize clearance and provide a solid mounting point for the OE lower control arms. Paired with a 3-piece heavy-duty front skid plate system, this creates a rigid subframe while adding protection for vital steering and driveline components. Specially designed ductile iron replacement steering knuckles are supplied to maintain proper steering geometry for ESC system compatibility.

The rear of this lift replaces the factory rear block with a tall lift block and longer U-bolts to lift and level the stance. BDS supplies extended brake lines to compensate for the additional lift height. Choose between specially tuned Fox 2.0 IFP Performance Series gas shocks or match the performance in the front with rear Fox 2.5 Performance Elite Series shocks featuring remote DSC reservoirs.
