4.5" 2014-2018 GMC Sierra 1500 4WD Lift Kit by BDS Suspension

This BDS Suspension BDS903FS/BDS903H 4.5-inch lift kit for the GMC Sierra 1500 4WD is a great way to give your truck additional fender clearance to fit larger diameter tires (up to 33 inches) and achieve a great new look. Included in this lift kit are the ductile cast iron replacement steering knuckles and high-clearance, full-width lower control arm crossmembers. These components maintain the factory geometry, allowing for excellent performance on and off-road, and are compatible with the factory traction control systems. The front differential is relocated for proper angles at the CV axles, allowing for the use of the stock front driveshaft. A 3-piece differential drop system keeps the differential secure, and the 3-piece front skid plate system protects the underside during off-road excursions. BDS front strut spacers provide the front lift.

The rear of the truck is lifted using an axle block and U-bolt kit, or you can upgrade to Glide-Ride rear leaf springs for improved traction control and performance.
