It uses nitrogen gas pressure to reduce oil aeration and maintain consistent damping, with loop-type bushings (3/4 inch ID) at both ends for direct bolt-on mounting. This shock helps control suspension movement, improving tire life and ride stability while decreasing excessive vibration. Replace when damping feels weak, the vehicle bounces excessively, or you see visible oil leakage.
