Smooth out the ride on your Mercedes-Benz and control body motion with the KYB Gas-a-just shock absorber KG4743, a rear high-pressure monotube unit that installs as a direct-fit replacement for the 1996-1999 Mercedes-Benz E300, 1996-2002 Mercedes-Benz E320, 1997 Mercedes-Benz E420, and 1998-2002 Mercedes-Benz E430. This KYB gas shock absorber is offered as an OE monotube replacement designed to restore your vehicle's original ride and handling capabilities.

  • Two working chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving and instant performance on demand.
  • Up to 25% more damping over original-equipment shocks, with valving designed specifically for the Mercedes-Benz E-Class — added damping for vehicles that work, tow, or run larger, heavier tires and wheels.
  • High-pressure monotube design separates the gas and oil for fade-free operation and instant response.
  • Triple chrome-plated piston rod: since leaking fluid can cause shock failure, this ultra-smooth rod is built to reduce seal wear.

Higher gas pressure responds quickly to help improve steering response, and the Gas-a-just helps keep Electronic Safety Systems performing as the manufacturer intended.

Frequently Asked Questions

What vehicles does the KYB KG4743 shock absorber fit?

Is this a front or rear shock?

This is a rear shock absorber. It is sold individually; for even, balanced ride control it's best practice to replace both sides on the same axle together as a matched pair.

What is a KYB Gas-a-just monotube gas shock?

It's a high-pressure monotube design with an air-free hydraulic piston/valve area for control and a high-pressure nitrogen gas chamber with a floating piston, separating gas and oil for fade-free operation.

What are signs my shocks may need replacing?

Common signs include excessive bouncing over bumps, nose-dive under braking, a floaty or unstable ride, and uneven tire wear. Diagnose the cause before replacing.

What interchange numbers does the KG4743 replace?

This KYB gas shock absorber cross-references to interchange numbers 69966 and 39021. Verify the number against your original part before ordering.
