  • Higher gas pressure responds quickly to improve steering response
  • Gas and oil are separated for fade-free operation and instant response
  • Designed for vehicles that work, tow and carry larger, heavier tires and wheels

Quick facts

  • Part: KYB 5540013 shock absorber
  • Also called: suspension shock absorber
  • Fits: 2013-2020 Lexus GS350 and other vehicles
  • Position: Rear
  • Condition: New

A worn suspension shock absorber can show up as fluid leaking from the body, a bouncy ride or slower steering response. Those signs alone do not prove the shock is at fault, since worn tires can feel similar. The rear takes two, one on each side of the axle, so order two and fit them together.

Fits

The vehicles it fits include the 2013-2020 Lexus GS350, the 2018-2019 Lexus GS300 and the 2015-2018 Lexus RC350.

What gas is in this KYB gas shock absorber?

Does the KYB Gas-a-just shock absorber have a chrome piston rod?

Yes, the piston rod is triple chrome plated and ultra-smooth. It is meant to reduce seal wear, because fluid leaking can be a cause of shock failure.

How do I spot a leaking rear shock absorber on this monotube?

With the engine off and the car cool, look for an oily film on the shock absorber body. A bouncy ride or slower steering response can also point to a worn shock absorber.

Is this monotube rear shock absorber designed for towing and larger wheels?

Yes, Gas-a-just monotubes like this one are designed for vehicles that work, tow and run larger, heavier tires and wheels.
