Refresh the front damping on your classic BMW with the KYB strut cartridge (P/N 365043), a nitrogen gas-charged Excel-G unit that drops into the front strut housings. It fits the 1982-1988 BMW 528E, 1983-1984 BMW 533I, 1985-1988 BMW 535I, 1988 BMW 535IS, and 1985-1989 BMW 635CSI — see the Buyer's Guide tab for engine-level details.
KYB's Excel-G line is built as Original Equipment for the Aftermarket (OEA), calibrated to restore the vehicle's designed control and handling rather than change it.
- Gas cartridge design: nitrogen gas-charged, twin-tube construction using OE-quality components.
- Triple lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific damping: hand-assembled valving intended to manage tire contact, steering response, and body movement.
- OEM-replacement: a KYB-recommended replacement gas cartridge that helps restore designed control and handling.
To reduce the chance of noise and vibration, KYB recommends installing new strut mounts (part number SM5053), and protecting the struts from dirt, debris, and salt with a KYB Strut Boot (part number SB105).
