Bring back controlled damping at the rear axle with the KYB shock absorber, MPN 344455 — a rear-position, direct-fit replacement for the 2003-2006 INFINITI G35 and 2003-2005 NISSAN 350Z. Part of the KYB Excel-G line, this is a nitrogen gas-charged, twin-tube unit calibrated to restore the vehicle's original, designed performance rather than change it, earning KYB's OEA (Original Equipment for the Aftermarket) classification.
Excel-G (OEA): Built on the same KYB OE assembly lines using OE-quality components; the #1 recommended Original Equipment replacement choice for Asian performance vehicles.
Twin-tube gas design: Nitrogen gas-charged, twin-tube construction that includes every quality component found in KYB's global OEM products.
Triple lip fluid seal: Uses a triple lip fluid seal to reduce the chance of oil and gas leaking out.
Supports electronic safety systems: Helps keep electronic safety systems performing as designed, since they depend on suspension, brakes and tires operating as the manufacturer intended.
To reduce the chance of noise and vibration, KYB recommends installing new strut mounts, part number SM5482. Sold individually; replace shocks as a matched pair per axle for balanced ride control.
