The knuckle-driven geometry preserves steering feel, while the three-piece sub-frame reduces installation complexity—so you can complete the upgrade with confidence. Pair this kit with extended shocks and the right wheels to unlock room for a rugged, 33"-tire setup, enhanced ground clearance, and improved approach/departure angles for off-road adventures or a bolder street-ready stance.
