The KYB Excel-G front strut for Buick LeSabre, Park Avenue and Riviera (1990s) is a nitrogen gas‑charged twin‑tube replacement calibrated to restore original ride control, stopping and handling characteristics. Built on KYB OE lines with OE-quality parts and classified OEA, it’s intended to return factory behavior rather than change it. KYB recommends strut boot SB104 to guard against dirt and corrosion.
