Bring back factory ride control with the KYB Gas-a-just Suspension Strut 5510014, a high-pressure monotube gas strut that drops in as a direct-fit replacement for the front right (passenger-side) corner of the 2014-2015 Lexus IS250 and 2014-2016 Lexus IS350. KYB struts like this Gas-a-just serve as an OE monotube replacement to help restore your vehicle's original capabilities.

  • Two 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 instant performance on demand.
  • Monotube design: the high-pressure monotube separates the gas and oil for fade-free operation and instant response.
  • Triple chrome plated piston rod: an ultra-smooth triple chrome plated chrome piston rod reduces seal wear (fluid leaking can be a cause of shock failure).
  • Steering response: higher gas pressure responds quickly to help improve steering response and helps keep electronic safety systems performing as designed.

This correct, monotube-designed OEM replacement helps restore the designed control and handling of the Lexus IS Sedan, and the Gas-a-just line is built for vehicles that work, tow, and run larger, heavier tires and wheels. Sold individually; replacing both sides of the axle together is recommended for balanced handling.

Frequently Asked Questions

Does this KYB strut fit my Lexus?

It's a direct-fit front right replacement for the 2014-2015 Lexus IS250 and the 2014-2016 Lexus IS350. Check the Buyer's Guide tab to confirm your exact vehicle.

What is a Gas-a-just monotube strut?

It's a high-pressure monotube gas strut with two separate chambers — an air-free hydraulic piston and valve area for control, and a high-pressure nitrogen gas area with a floating piston for a comfortable ride.

Why choose a monotube design?

Separating the gas and oil in the high-pressure monotube gives fade-free operation and instant response compared with designs where the two mix.

Should I replace both sides at once?

KYB sells this strut individually. Replacing both struts on the same axle together is recommended for balanced, even handling.

What are signs this strut may need replacing?

Excessive bouncing, nose dive under braking, poor steering response, uneven tire wear, or fluid leaking from the strut can be signs this strut may need replacing.
