• Heavy-duty radius arms with rubber bushings — maintain factory suspension angles for balanced on- and off-road ride quality while absorbing vibration and impact.
• Adjustable alignment cam — allows caster adjustment at the axle so your truck handles straight and true after install.
• N3 series shock absorbers — application-valved for balanced performance on pavement and rough terrain, tuned specifically for this kit.
• Add-a-leaf kit — reinforces the rear suspension to handle the lift and maintain proper geometry.
