KYB Suspension Strut P/N:551104

Description

Firm up front-end control and resist damping fade with the KYB Gas-a-just High Pressure Monotube Gas Strut (MPN 551104). This front suspension strut is a direct-fit replacement for the 2003-2009 Toyota 4Runner, 2007-2009 Toyota FJ Cruiser, and 2005-2015 Toyota Tacoma. KYB notes its components and valving are designed specifically for Toyota Tacomas, and the Gas-a-just adds up to 25% more damping performance over original equipment shocks.

Monotube gas design: Two separate working chambers — an air-free hydraulic piston and valve area for responsiveness, plus a high-pressure nitrogen gas area with a floating piston that separates gas and oil for fade-free operation and instant response.
Quick steering response: The higher gas pressure of the Gas-a-just responds quickly to help improve steering response.
Built for hard use: Monotubes include additional damping over the OE design for vehicles that work, tow, and run larger, heavier tires and wheels.
Reduced seal wear: An ultra-smooth triple chrome plated piston rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.

KYB also notes the Gas-a-just helps keep Electronic Safety Systems performing as designed, since those systems depend on the suspension, brakes, and tires operating as the vehicle manufacturer intended.

What is the position of this strut?

This is a front suspension strut for the listed Toyota applications.

How is a monotube strut different from a twin-tube design?

The Gas-a-just uses two separate chambers — an air-free hydraulic piston/valve area and a high-pressure nitrogen gas area with a floating piston — separating gas and oil for fade-free operation.

Does this strut add damping over the factory shocks?

KYB states the Gas-a-just adds up to 25% more damping performance over original equipment shocks, with extra damping for vehicles that work, tow, or run larger, heavier tires and wheels.

What are signs my strut may need replacing?

Common signs include fluid leaking from the unit, reduced ride control, excessive bounce, or poor steering response. Have the suspension inspected to confirm the cause before replacing.
