KYB Gas-a-just Front Right Monotube Strut for 2015-2017 Subaru WRX STI (5510021)
$287.79
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2017 Subaru WRX STI models including Base, Launch Edition, Limited, and Series.HyperBlue.
The KYB Gas-a-just monotube strut is engineered as a high-performance OE replacement to restore and enhance your vehicle's handling stability. Unlike standard twin-tube designs, this monotube construction eliminates aeration and foaming for more consistent damping during aggressive driving or over rough surfaces.
This strut features two distinct working chambers: an air-free hydraulic piston and valve area for immediate responsiveness, and a separate high-pressure nitrogen gas area with a floating piston. The floating piston keeps the gas and oil separated, preventing performance fade and ensuring the strut provides a comfortable ride during cruising while adding instant control on demand.
- Manufacturer Part Number: 5510021
- Position: Front Right
- Design: High-pressure nitrogen monotube with floating piston
- Construction: Seamless cylinders and heavy-duty seals for longevity
- Benefit: Replaces worn factory struts to restore original steering response and brake dive control
Protect the polished piston rod from dirt, debris, and road salt by installing a new KYB strut boot (sold separately as part number SB123) during replacement.
