KYB Suspension Strut P/N:339089

Description

Restore the designed ride control, stability, and handling of your 2004-2008 Pontiac Grand Prix with the KYB Excel-G Front Suspension Strut 339089. It drops in as a direct-fit front replacement, and as an OEA (Original Equipment for the Aftermarket) unit it's built on the same KYB OE assembly lines with the same OE-quality components, calibrated to restore original designed performance rather than change it.

Nitrogen gas-charged, twin-tube design: includes every quality component found in KYB's global OEM products and is a preferred choice among professional technicians.
Triple-lip fluid seal: helps reduce the chance of oil and gas leaking out.
Vehicle-specific damping valves: hand-assembled in-house to help correctly manage tire contact, steering response, and body movement.
Strong, thick strut body and brackets: KYB builds among the thickest in the industry to minimize flex and help maintain correct alignment.

Because electronic safety systems depend on the suspension working as intended, the Excel-G helps keep those systems performing as designed. To reduce the chance of noise and vibration, KYB recommends installing new strut mounts (part number SM5568), and protecting your new struts with a KYB Strut Boot (part number SB127). Made in USA.
