KYB 340042 Excel-G Rear Strut for 2017+ Subaru Impreza AWD

Vehicle Fitment

• 2017+ Subaru Impreza, AWD, Rear - exact upper model-year varies by source (2019 vs. 2023); confirm your specific model year against KYB's official fitment tool

Fitment Notes

• Rear position; one source lists this as usable on either left or right rear, but this symmetry is not independently confirmed elsewhere - verify before assuming single-part coverage for both rear corners
• Sold individually as a bare strut assembly
• Two sources give differing extended/compressed length specifications for this part - confirm exact dimensions with your seller if precise measurements matter for your installation

Features

• Nitrogen gas-charged, twin-tube design for consistent damping performance
• Sintered-iron pistons and guide rods for added strength
• Hard-chrome piston rods for superior durability
• Seamless cylinders and eyerings
• Patented check valve minimizes foaming and aeration to maintain control under demanding conditions
• Vehicle-specific, hand-assembled damping valves, built in a pressurized clean room to avoid contamination
• Ultra-smooth triple chrome-plated piston rod reduces seal wear
• Multi-lip synthetic oil seal with wiper keeps fluid in and contaminants out
• Restores the vehicle's original designed handling and stability

Product Description

The KYB 340042 is a nitrogen gas-charged, twin-tube Excel-G rear strut engineered for the 2017 and newer Subaru Impreza AWD. Built on the same OE assembly lines KYB uses for original-equipment production, this strut uses vehicle-specific, hand-assembled damping valves - built in a pressurized clean room to avoid contamination - to restore the Impreza's factory rear handling and stability.

Constructed with sintered-iron pistons and guide rods, hard-chrome piston rods, and a patented check valve to minimize foaming, this strut is designed to maintain consistent control even under demanding driving conditions. The multi-lip synthetic oil seal and triple chrome-plated piston rod work together to reduce wear and keep the strut performing reliably over the long term.

This strut is a good fit for Impreza AWD owners performing a rear suspension replacement. Given the year-range and dimensional discrepancies found between otherwise reliable sources, confirm your exact model year and required strut dimensions against KYB's official fitment tool before ordering, and verify whether one part number covers both rear positions or if side-specific parts are needed for your particular Impreza configuration.
