KYB Gas-a-Just Rear Monotube Shock Absorber for 2014-2021 Lexus IS200t/IS250/IS300/IS350 (5540004)
$111.22
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2014-2021 Lexus IS200t, IS250, IS300, and IS350. The KYB Gas-a-Just 5540004 is a high-pressure monotube shock absorber engineered as an OE-style replacement to restore the original damping performance and handling characteristics of your Lexus IS. Unlike standard twin-tube designs, this monotube shock eliminates aeration and foaming for more consistent, fade-free responsiveness.
The Gas-a-Just features two distinct working chambers: an air-free hydraulic piston and valve area for precise control, and a separate high-pressure nitrogen gas chamber with a floating piston. This design allows for a smooth, compliant ride during normal driving while providing instant performance and stability when the suspension is pushed. By maintaining consistent tire-to-road contact, these shocks ensure that vehicle electronic safety systems, such as ABS and stability control, function as intended.
- Manufacturer Part Number: 5540004
- Position: Rear
- Design: Monotube High-Pressure Gas
- Body Construction: Seamless cylinder for increased strength and durability
- Hardware: Includes necessary mounting bushings and sleeves where applicable
