KYB 553382 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock for Volvo XC90

KYB Gas-a-Just 553382 is a rear suspension shock absorber built as an OE-style monotube replacement for the Volvo XC90. It is designed for 2003-2014 Volvo XC90 rear applications, excluding rear air leveling models, and restores controlled damping for daily driving, towing, and heavier wheel-and-tire setups.

Gas-a-Just Product Line

The KYB Gas-a-Just line uses a monotube design with separate hydraulic and high-pressure gas chambers. That layout supports quick response, consistent control, and fade-resistant operation when the suspension is working harder than stock.

Key Features

• Adds up to 25% more damping performance over original equipment shocks
• Components and valving are designed specifically for the Volvo XC90
• High-pressure monotube construction separates gas and oil for consistent response
• Higher gas pressure improves steering response and suspension control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Includes dust cover
• R-stop and B-stop features are listed for this application

Detailed Description

KYB 553382 is engineered for rear suspension service on the Volvo XC90, with valving matched to the vehicle’s original behavior while adding additional damping capacity. The monotube design uses an air-free hydraulic working area for control and a separate nitrogen gas chamber with a floating piston for immediate reaction to road inputs. This helps maintain stable ride quality during normal driving and improves control when the vehicle carries extra load or larger tires and wheels. This part cross-references Volvo 306395130 and 312014520 for the same application.

What It Helps Address

• Excessive rear bounce after bumps
• Reduced control when towing or carrying heavier loads
• Soft or delayed suspension response
• Fluid leakage from worn shock seals
• Loss of ride consistency on the Volvo XC90 rear suspension

Installation Notes and Tips

• Fits 2003-2014 Volvo XC90, rear, excluding rear air leveling
• Verify compressed length, extended length, and stroke before installation: 11.38 in compressed, 17.01 in extended, 5.63 in stroke
• Upper mount type is S1 (12MM); lower mount type is E2 (12x74)
• KYB recommends replacing strut mounts, part number SM5165, to reduce noise and vibration
• KYB recommends a strut boot, part number SB103, to help protect the shock from dirt, debris, and salt

Quality Assurance

KYB is a suspension manufacturer known for OE replacement engineering, and Gas-a-Just shocks are built to restore original vehicle capability with monotube construction and application-specific valving for the Volvo XC90.
