KYB Suspension Strut Cartridge P/N:363003
Help bring back the ride control, stability, and handling your BMW was built with using the KYB strut cartridge 366005, a nitrogen gas-charged Excel-G front cartridge. It installs as a direct-fit front replacement for many BMW models, among them the 1993-1994 BMW 740iL, 1988-1994 BMW 750iL, and 1989-1990 BMW 525i — see the "Vehicles it fits" section for the full list and engine-level fitment.
Part of KYB's Excel-G line, this gas cartridge is calibrated to restore the vehicle's original designed damping rather than change it, earning the OEA (Original Equipment for the Aftermarket) classification.
KYB recommends installing new strut mounts (part number SM5053) and protecting the strut with a KYB Strut Boot (part number SB105). Sold individually; for even, balanced handling, replace both front sides as a matched pair.
