Smooth out a heavy-working rear end with the KYB Gas-a-just Shock Absorber 551140, a high-pressure monotube gas shock. This KYB shock absorber installs at the rear position on the 2010-2012 Hyundai Santa Fe and 2011-2013 Kia Sorento, with valving and components designed specifically for Asian SUVs.

  • Monotube gas design: Two separate working chambers — an air-free hydraulic piston/valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving.
  • Fade-free operation: Separating the gas and oil helps the shock resist aeration fade and respond quickly, improving steering response through higher gas pressure.
  • Extra damping: Adds up to 25% more damping performance over original-equipment shocks, built for vehicles that work, tow, and run larger, heavier tires and wheels.
  • Triple chrome-plated rod: Since leaking fluid can cause shock failure, the ultra-smooth triple chrome-plated piston rod is designed to reduce seal wear.

KYB notes the Gas-a-just also helps keep electronic safety systems performing as the vehicle manufacturer intended. Sold individually — replace both rear shocks as a matched pair for balanced ride control.

Frequently Asked Questions

What vehicles does the KYB 551140 shock absorber fit?

It fits the rear position on the 2010-2012 Hyundai Santa Fe and 2011-2013 Kia Sorento. Check the Buyer's Guide tab to confirm the fit for your vehicle.

Is this a KYB gas shock absorber or a twin-tube?

It is a high-pressure monotube gas shock — the KYB Gas-a-just design that separates the gas and oil in two chambers for fade-free operation, rather than a traditional twin-tube.

How is this KYB gas shock absorber different from a standard OE shock?

KYB states it adds up to 25% more damping over original-equipment shocks, with valving and components designed specifically for Asian SUVs that work, tow, or run larger tires and wheels.

Do I need to replace both rear shocks?

The 551140 is sold individually. Replacing both rear shocks together as a matched pair is recommended for even, balanced ride control.

What does the triple chrome-plated piston rod do?

Fluid leaking can cause shock failure, so the ultra-smooth triple chrome-plated piston rod is designed to reduce seal wear over time.
