It restores original ride height, auto‑leveling function and smooth driving comfort after original air bag leaking, collapse or damage. Plug‑and‑play, matches original mounting points without modification. Solves common air suspension problems: rear axle sitting low, air suspension warning light on dashboard, uneven rear height, hissing air leak noise. Every air spring is strictly pressure‑leak tested before shipment. Suitable for repair shops, garages and wholesale buyers. Please verify your original OE number, chassis code C7‑4G and PR‑1BK suspension option before ordering.
