About this kit
6-Inch Vertex 2.5 Lift Kit with V2 Rear Shocks, fitment-checked
Rough Country 88357 is a 6-inch lift kit for the 2025 Ram 1500 4WD, pairing adjustable Vertex 2.5 front struts with a V2 monotube rear shock pair and 6-inch dual-rate rear springs. Hub sizing rules this version out on trucks that left the factory with 22-inch wheels. Wheels of 20 inches or larger are required.
This 6-inch lift kit for the 2025 Ram 1500 4WD runs adjustable Vertex 2.5 front struts, left and right, over a V2 monotube rear shock pair and 6-inch dual-rate rear springs, with a crossmember box kit and driver and passenger knuckles completing the package. Check the truck first: hub sizing means it does not work with factory 22-inch wheels, and 20-inch or larger wheels are required. Trucks with 4-Corner Air-Suspension, standard on Limited and Limited Longhorn, are out, as are Warlock models carrying a 1-inch factory lift. It is not recommended for AWD. A downloadable installation guide is available.
