2515-4/7 4-Inch Front / 7-Inch Rear Drop Kit

The DJM Suspension DJM2515-4/7 Complete Lowering Kit is engineered to dramatically lower the stance of 2015-2018 Chevy Silverado and GMC Sierra trucks by 4 inches in the front and 7 inches in the rear. In the front, the kit features precision-engineered upper and lower control arms that are built around the factory strut. This design corrects ball joint angles, ensures proper wheel clearance, and allows for the retention of stock alignment specifications. The control arms come pre-assembled with new ball joints, urethane bushings, and twin-tube pivot sleeves for simplified installation. The rear of the truck is lowered by 7 inches using a heavy-duty axle flip system. This system includes pinion-adjustable axle brackets, new U-bolts, spring plates, and all the necessary hardware for proper installation and driveline alignment. Shocks are included to properly control suspension movement at the lowered ride height. For certain 2015 models, including some 2014 4x4 and early 2016 configurations, it is advised to verify compatibility before ordering to ensure correct component selection. Additional recommended or replacement parts include Rear Shock 1800, Upper Ball Joint 6292, Lower Ball Joint 6015, Upper Bushing Kit BK2007U, and Lower Bushing Kit BK2007L.
