Frequently Asked Questions
Should KYB struts be replaced in pairs?
Replacing both struts on the same axle is generally recommended so damping and handling remain balanced. Follow KYB and vehicle service guidance.
Does this strut include the spring and upper mount?
Only when those components are expressly listed for the exact part number. A bare strut does not automatically include the spring, mount, bearing, boot, bump stop, or hardware.
Is an alignment required after replacing a strut?
Yes. A strut replacement can change suspension geometry. Complete installation and ride-height checks, then perform a professional alignment.
Installation Instructions
Follow the current KYB instructions and vehicle service manual for part number 551131. Support the vehicle safely, use approved spring-compression equipment when required, follow position-specific torque procedures, and verify brake lines, sensors, steering movement, suspension travel, and wheel and tire clearance. Complete an alignment whenever the repair affects suspension geometry.

Compare Lexus IS200T intake and brake options using the exact 2.0L turbo application. The displayed Injen intake references cover 2016–2017 IS200T vehicles; verify the exact part number and installation requirements. Intake Connections and Finish Compare the sensor housing, hose connections, brackets and supplied hardware before choosing polished or black finish. Confirm application coverage and emissions restrictions for the selected intake. The shared RC200T reference does not extend coverage to every RC or IS engine. Keep the actual IS200T engine and production details with the manufacturer part number. Brakes, Dampers and Pedal Devices For rear brake kits, identify calipers, pad shape, rotor dimensions and complete axle contents. Match suspension dampers by actual production, drivetrain and position, especially where the title references earlier IS250/350 vehicles. For pedal-response devices, verify vehicle electronics and connector. A displayed RC F axle-back exhaust title does...

Intake and Exterior Accessory Fit The displayed Injen intake versions reference 2006–2020 IS350 3.5L V6 applications. Confirm exact year coverage, sensor provisions, hoses, brackets and emissions requirements. For the listed 2006–2013 tape-on window deflectors, compare body and door configuration, outside-mount pattern and four-piece contents. The intake year range does not establish deflector body coverage. Brake Kits and Pedal Devices Match rear pads and rotors to calipers, backing-plate shape and rotor dimensions. Review F Sport or other brake-package requirements and distinguish supporting hardware from complete friction kits. For a pedal-response device, verify the IS350 connector and supported application.
