A JK that has outgrown its stock suspension needs more than taller springs. Bigger tires bring steering angle, axle position and sway bar geometry problems that show up on the first rocky climb.
This BDS 4.5 in lift kit addresses them as a system. Front and rear Pro-Ride coil springs, bump stop extensions, a drop pitman arm, track bar relocation brackets and fixed length control arms reposition the axles and correct steering, while NX2 Nitro gas shocks handle damping. It clears tires up to 37 in.
Install the kit, align the front end, and the Jeep sits level with room for bigger rubber.
