KYB Suspension Shock Absorber P/N:343487
Keep your Tacoma's rear suspension planted and fade-free with the KYB Gas-a-just High Pressure Monotube Gas Shock (MPN 554351), a rear-position shock absorber that drops in as a direct-fit replacement for the 2005-2015 Toyota Tacoma. KYB built its components and valving specifically for Toyota Tacomas, so it damps the way this truck's rear suspension is meant to.
Higher gas pressure responds quickly to improve steering response, and KYB designed the Gas-a-just to help keep Electronic Safety Systems performing as intended. Signs your rear shocks may need replacing include excessive bouncing, fluid leaks, and reduced ride control.

This part cross-references / interchanges with the following part numbers:
What vehicle does this KYB shock fit?
It is a direct-fit rear shock absorber for the 2005-2015 Toyota Tacoma, with components and valving KYB designed specifically for Toyota Tacomas. See the Buyer's Guide tab to confirm your truck.
Is this a front or rear shock?
This is a rear-position shock absorber. It is sold individually; replacing both rear shocks together as a matched pair is recommended for balanced ride control.
What makes the Gas-a-just monotube different from a twin-tube shock?
It uses two separate chambers — an air-free hydraulic piston and valve area, plus a high-pressure nitrogen gas area with a floating piston — and separates gas from oil for fade-free operation and instant response.
Why does the piston rod have a triple chrome-plated finish?
The ultra-smooth triple chrome-plated rod helps reduce seal wear. Since fluid leaking can be a cause of shock failure, reducing seal wear supports longer service.
What are signs my rear shocks may need replacing?
Common signs include excessive bouncing over bumps, reduced ride control, uneven tire wear, and visible fluid leaking from the shock. Diagnose the cause before replacing.
