KYB Suspension Shock Absorber P/N:343158
Restore the designed control and handling of your Toyota SUV with the KYB Excel-G Rear Shock Absorber 344410. This nitrogen gas-charged, twin-tube gas shock drops in as a direct-fit replacement for the 2003-2009 Toyota 4Runner and 2007-2009 Toyota FJ Cruiser (see the Buyer's Guide tab for engine-level fitment). KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is built on the same 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.
Shocks wear as a set — replace both sides on the same axle together for balanced ride control.
