Steady the ride out back with the KYB shock absorber, part number 554351 — a High Pressure Monotube Gas-a-just that drops in as a rear replacement for the 2005-2015 Toyota Tacoma, with components and valving designed specifically for Toyota Tacomas.

  • 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 area with a floating piston for a comfortable ride during normal driving and added performance on demand.
  • Fade-free operation: The high-pressure monotube separates the gas and oil, so the shock never experiences fade due to aeration and delivers instant response.
  • 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.
  • Built to work: Adds up to 25% more damping over original equipment shocks, with extra damping over the OE design for vehicles that work, tow, and run larger, heavier tires and wheels.

The higher gas pressure responds quickly to improve steering response and helps keep Electronic Safety Systems performing as designed. Sold individually; replace both rear shocks together as a matched pair for balanced handling.
