Keep your Toyota Tundra's rear suspension planted and composed with the KYB Gas-a-just Suspension Shock Absorber 554367, a high-pressure monotube gas shock that installs as a direct-fit rear replacement for the 2007-2021 Toyota Tundra. The Gas-a-just uses two separate 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 — so it can automatically adjust to your driving and never fades due to aeration.

  • Monotube gas design: 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.
  • Tundra-specific tuning: components and valving designed specifically for Toyota Tundras, with added damping for trucks that work, tow, and run larger, heavier tires and wheels.
  • Triple chrome-plated piston rod: an ultra-smooth triple chrome plated 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 KYB designed it to help keep Electronic Safety Systems performing as intended. If worn rear shocks are behind a bouncy, floaty ride or poor body control, this is the replacement.
