KYB 5530014 Suspension Shock Absorber - Rear

KYB Gas-a-Just Rear Shock for QX30

The KYB Gas-a-just 5530014 is a rear suspension shock absorber built as an OE monotube replacement for the 2017-2019 INFINITI QX30. It restores original ride control with a design that separates hydraulic response from high-pressure nitrogen gas support for consistent damping in everyday driving.

Gas-a-Just Product Line

KYB Gas-a-just shocks use a monotube layout with two working chambers: an air-free hydraulic piston and valve area for quick response, plus a high-pressure nitrogen gas chamber with a floating piston. That setup helps maintain controlled ride quality while adding firmer performance when the suspension is working harder. The KYB 5530014 follows that OE-style approach for rear suspension service on the INFINITI QX30.

Key Features

• OE replacement for the original rear shock application
• Compressed length: 17.32 in.
• Extended length: 25.24 in.
• Stroke length: 7.92 in.
• Lower mount type: E2 (10.2 x 48)
• Upper mount type: S1 (10MM)
• Dust cover included

Detailed Description

Built for rear suspension service, KYB part number 5530014 is engineered for 2017-2019 INFINITI QX30 models with a rear shock application. Its monotube construction supports stable damping performance, while the separate gas and hydraulic chambers help maintain control and ride comfort during normal road use. 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 rear-end stability over uneven pavement
• Harsh or inconsistent rear ride quality
• Worn original rear shock performance
• Loss of controlled damping in daily driving

Installation Notes

Fits 2017-2019 INFINITI QX30, rear. Verify compressed length, extended length, stroke length, and mount types before installation to confirm proper suspension travel and fitment. KYB 5530014 is a rear shock absorber, so it should be matched to the rear position only.

Quality Assurance

KYB is known for OE-style suspension replacement parts, and the Gas-a-just line is built to restore original vehicle capability with a monotube design and controlled gas pressure support. Part number 5530014 is specified for the rear suspension application on the INFINITI QX30.
