About this kit
2-Inch Front / 4-Inch Rear Lowering Kit, fitment-checked
Rough Country 71630 is a 2-inch front, 4-inch rear lowering kit for 2WD Chevrolet Silverado 1500 and GMC Sierra 1500 models. Rear drop can be set between 4 and 4.5 inches, and the kit works only with aluminum or stamped steel control arms. Wheels must be 18 inches or larger, and the install calls for a rear axle flip plus minor cutting and drilling.
This 2-inch front, 4-inch rear lowering kit for 2014-2018 Silverado 1500 and Sierra 1500 2WD trucks also covers the 2019 Silverado 1500 LD in RWD form, spanning WT and Custom through LTZ, High Country, and Denali as shown in the fitment section. Two boxes ship: the aluminum lower-control-arm lowering knuckles and the lowering kit hardware. Plan on a rear axle flip and some cutting and drilling, and confirm your truck has aluminum or stamped steel arms first. Alignment returns to factory specification, and the setup can be reversed to stock height later.
