Keep the rear end of your work van, SUV or Suburban planted with the KYB shock absorber KG54100, a High Pressure Monotube Gas Shock (Gas-a-just) that installs as a direct-fit rear replacement for the 1992-1999 Chevrolet and GMC C1500/C2500 Suburban, 1995-2000 Chevrolet Tahoe, 1995-1999 GMC Yukon, and the 1996-2007 Chevrolet Express 2500 and GMC Savana 2500 vans and more — see the Buyer's Guide tab for the full list.
Monotube Gas-a-just design: two separate working chambers — an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas chamber with a floating piston that separates the gas and oil for fade-free operation and instant response.
Up to 25% more damping: adds up to 25% more damping performance over original equipment shocks, with components and valving designed specifically for GM Vans.
Built to work and tow: includes additional damping over the OE design for vehicles that work, tow, and run larger, heavier tires and wheels.
Triple chrome-plated rod: an ultra-smooth triple chrome plated piston rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
The higher gas pressure responds quickly to improve steering response and helps keep Electronic Safety Systems performing as designed. Sold individually; replacing both rear shocks together as a matched pair is recommended for balanced ride control.
