KYB Suspension Strut P/N:551128
Restore the designed ride control and handling of your SUV with the KYB Excel-G Suspension Strut 339211, a nitrogen gas-charged, twin-tube gas strut for the rear left position. It fits the 2006-2007 Lexus RX400H and 2006-2007 Toyota Highlander (see the Buyer's Guide tab for engine-level fitment). Built on the same KYB OE assembly lines with the same OE-quality components, the Excel-G is calibrated to restore original, designed performance rather than change it — earning it KYB's OEA (Original Equipment for the Aftermarket) classification.
Because the suspension, brakes, and tires work together, the Excel-G also helps keep electronic safety systems performing as designed. Struts install as left/right pairs — this listing is for one strut; KYB recommends replacing both sides together for balanced ride control. KYB also suggests new strut mounts (SM5492) and a strut boot (SB104) at installation.

Should I replace any other parts at the same time?
KYB recommends installing new strut mounts (part SM5492) and protecting the struts with a strut boot (part SB104) to reduce the chance of noise, vibration, and contamination.
