Unbeatable Performance: This 4.75-inch combo kit delivers enhanced ground clearance and ride quality, combining our premium N3 series shocks with a dual-lift system. The Nitrogen-charged N3 shocks feature 10-stage velocity-sensitive valving, custom-tuned for this specific application, ensuring a perfect balance of on-road comfort and off-road control in any driving condition.
