About this kit
7.5-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 25330 is the N3 shock configuration of the 7.5-inch lift kit for 2011-2019 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD trucks. Two N3 shock pairs cover front and rear. Factory wheels will not clear, and dually or Magnetic Ride Control trucks are excluded.
Ordered as the N3 configuration, this 7.5-inch lift kit for the 2011-2019 Silverado and Sierra 2500 HD and 3500 HD (the fitment list also shows a 2015 Silverado 3500 RWD WT) arrives as boxed subassemblies: crossmember box, main and rear kit boxes, a no-torsion-drop bracket box, driver and passenger knuckles, and two N3 shock pairs. Factory wheels do not clear; trucks built with 17-inch wheels need aftermarket wheels of 17 inches or larger for caliper and rotor clearance. Plan on minor cutting and drilling. Gas trucks may need exhaust work for driveshaft clearance, and rear overload springs call for u-bolt kit 7664.
