KYB 555060 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Nissan Xterra

The KYB Gas-a-just 555060 is a rear suspension shock absorber built for 2005-2015 Nissan Xterra applications. It uses a monotube design with separate gas and oil chambers for quick response, consistent damping, and reduced fade during demanding driving.

Key Features

• Fits 2005-2015 Nissan Xterra, rear
• Up to 25% more damping performance than original equipment shocks
• Monotube construction separates gas and oil for fade-resistant operation
• Higher gas pressure improves steering response and suspension control
• Designed specifically for the Nissan Xterra platform
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Dust cover included
• Part number: 555060

Product Details

KYB Gas-a-just shocks are engineered for vehicles that work harder than a standard commuter setup. On the Nissan Xterra, the added damping helps manage towing loads, heavier wheels and tires, and uneven road conditions while maintaining a controlled ride. The monotube layout allows the shock to react quickly to suspension movement, and the high-pressure nitrogen gas chamber supports consistent performance under repeated use. If you are replacing a worn rear shock on a Nissan Xterra, KYB 555060 provides a direct-fit suspension solution with application-specific valving.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear-end bounce or excessive oscillation over bumps
• Reduced control when carrying cargo or towing
• Soft or delayed shock response on rough pavement
• Suspension fade during repeated compression and rebound cycles
• Steering response that feels less precise after shock wear

Installation Notes and Tips

Compatible with 2005-2015 Nissan Xterra rear suspension applications. Verify compressed length, extended length, and mount style before installation: compressed length 12.63 in, extended length 19.09 in, stroke length 6.46 in, lower mount E2(14X42), upper mount E1. Inspect related suspension components, mounting points, and tire condition during replacement to help restore proper ride control.

Quality Assurance

KYB designs the Gas-a-just line with monotube construction, high-pressure gas separation, and a chrome piston rod to support consistent damping and reduced seal wear. The 555060 is built around the Nissan Xterra application and follows KYB’s performance-focused shock absorber design standards.
