Restore the factory ride and handling of your Toyota Sienna with the KYB Excel-G Suspension Strut 334430, a nitrogen gas-charged, twin-tube unit engineered to bring back the vehicle's originally designed control, stability, and lane-change response rather than change it. It installs in the front right position as a direct-fit replacement for the 2004-2006 Toyota Sienna (see the Buyer's Guide tab for engine-level detail).
KYB classifies the Excel-G as OEA (Original Equipment for the Aftermarket) — built on the same assembly lines and with the same OE-quality components used for its new-vehicle programs.
- Twin-tube, nitrogen gas-charged design: calibrated to restore original, designed damping performance.
- 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 brackets: minimize flex to help maintain correct alignment.
Worn struts can show up as excessive bounce, nose-dive under braking, poor body control, or reduced stability. The Excel-G also helps keep electronic safety systems performing as the manufacturer intended. Made in the United States. To reduce the chance of noise and vibration, KYB recommends installing new strut mounts, part number SM5180.
