Product Details

Unity Automotive has focused on aftermarket suspension for decades, and the Gas Charged Shock Absorber line is built to OEM specifications for direct replacement use. This rear shock absorber for Nissan Altima models from 2002 through 2006 is engineered to help maintain ride stability, body control, and predictable damping response. The nitrogen gas charge supports more consistent performance under changing road conditions, while the painted finish adds a durable exterior coating. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive rear bounce after bumps
• Reduced stability over uneven pavement
• Loose or unsettled rear suspension feel
• Uneven damping response during daily driving
• Worn rear shock performance on a Nissan Altima

Installation Notes

Verify rear fitment by matching the vehicle year, make, and model before installation. Compare compressed length, extended length, and travel length to the original shock absorber to confirm proper suspension geometry. For best results, inspect related rear suspension components for wear before replacing the shock.
