KYB KG5553 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Volvo 240

The KYB Gas-a-just KG5553 is a rear suspension shock absorber for 1990-1993 Volvo 240 models. Built as a monotube design, it separates gas and oil for consistent damping response and reduced fade during repeated suspension movement.

For Volvo 240 rear shock replacement, KG5553 is engineered to deliver firmer control than a conventional twin-tube design while maintaining a controlled ride in normal driving.

Key Features

• Monotube construction with separate gas and hydraulic working chambers
• Up to 25% more damping performance than original equipment shocks
• High-pressure nitrogen gas for quick response and fade-resistant operation
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Designed specifically for Volvo applications
• Supports vehicles used for towing, heavier tires, and added load demands
• Dust cover included

Product Details

KYB Gas-a-just shocks are built for drivers who want more immediate steering response and better body control from the suspension. The KG5553 uses a high-pressure monotube layout that keeps the gas and oil separated, helping the shock maintain performance as conditions change. For 1990-1993 Volvo 240 rear suspension service, this design is a direct fitment-focused option for restoring control and consistency.

This part cross-references Monroe Shocks & Struts (e.g., 5868) for the same application.

What It Helps Address

• Excessive rear bounce after bumps or dips
• Reduced damping control from worn shock absorbers
• Fluid leakage caused by seal wear
• Delayed steering and chassis response
• Fade during repeated suspension movement

Installation Notes and Tips

Fits 1990-1993 Volvo 240, rear. Verify compressed length, extended length, and mount style before installation: compressed length 11.57 in, extended length 17.36 in, stroke length 5.79 in, lower mount E2 (12.8 x 48), upper mount E2 (12.8 x 41.3). Confirm the existing rear shock matches these dimensions and mounting points before replacement. KG5553 is also referenced by part number KG5553 for catalog lookup and fitment verification.

Quality Assurance

KYB designs the Gas-a-just line with performance-oriented valving and a monotube layout to maintain consistent damping response. The KG5553 is built for Volvo-specific application tuning and is intended to support the suspension behavior expected by the vehicle manufacturer’s original systems.
