KYB KG54101 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for GM Vans and SUVs

The KYB Gas-a-just KG54101 is a monotube suspension shock absorber built for rear applications on select Chevrolet and GMC vans and SUVs. It uses separate gas and oil chambers for quicker response, consistent damping, and reduced fade during demanding driving.

For drivers of Chevrolet Express 3500, GMC Savana 3500, and related GM rear suspension applications, the KYB Gas-a-just KG54101 adds controlled damping for towing, hauling, and vehicles running larger wheels and tires.

Key Features

• Up to 25% more damping performance than original equipment shocks
• Monotube design separates gas and oil for fade-resistant operation
• High-pressure nitrogen gas supports fast steering response and stable control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Components and valving are tuned for GM van applications
• Dust cover included

Product Details

The Gas-a-just line from KYB is designed around a monotube shock architecture that reacts quickly to suspension movement. Unlike a traditional twin-tube design, the KG54101 uses an air-free hydraulic working area for control and a separate high-pressure gas chamber for immediate performance when load or road conditions change. That makes it a practical choice for rear suspension service on Chevrolet Express 3500, GMC Savana 3500, and other listed GM applications.

Part number KG54101 is also cross-referenced to Monroe Shocks & Struts 911526 for the same application. This shock absorber is a direct-fit rear suspension component for select 1992-2002 Chevrolet and GMC trucks, vans, and SUVs listed below.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced control when towing or carrying heavy loads
• Shock fade from heat and aeration
• Loose steering feel caused by worn rear damping
• Ride instability on vehicles with larger, heavier tires and wheels

Installation Notes

• Fits rear position only on the listed applications.
• Verify compressed length, extended length, and mount style before installation.
• Lower mount type: E2 (14.6 x 41); upper mount type: E3 (61.6 x 87 x 0).
• Dust cover is included; internal rebound spring and B-stop are not included.
• Follow the manufacturer’s instructions for vehicles that require suspension strut and coil spring assembly service.

Quality Assurance

KYB designs the Gas-a-just line for controlled damping and consistent response in demanding rear suspension use. The KG54101 is engineered to maintain performance under load and to support the suspension behavior expected by the vehicle manufacturer.
