Help restore the designed ride control, stability, and handling of your Acura TSX with the KYB Excel-G Suspension Strut 340048. It installs as a direct-fit replacement in the front left position on the 2009-2014 Acura TSX (see the Buyer's Guide tab for engine-level detail). KYB is a leading OE supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is built on the same KYB OE assembly lines using the same OE-quality components — calibrated to restore original, designed performance rather than change it, earning it the OEA (Original Equipment for the Aftermarket) classification.
- Nitrogen gas-charged twin-tube design: includes every quality component found in KYB's global OEM products.
- Triple-lip fluid seal: helps reduce the chance of oil and gas leaking out.
- Vehicle-specific, hand-assembled damping valves: manage tire contact, steering response, and body movement.
- Strong, thick strut body and bracket: minimizes flex to help maintain correct alignment.
Because electronic safety systems depend on the suspension, brakes, and tires working as intended, the Excel-G helps keep those systems performing as designed. Protect your new strut from dirt, debris, and salt with a KYB Strut Boot, part number SB108.
