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 the 1989-1990 BMW 525I, 1988-1990 BMW 535I, 1988-1990 BMW 735I, 1988-1990 BMW 735IL, 1993-1994 BMW 740IL, and 1988-1994 BMW 750IL — see the Buyer's Guide tab for 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.
- Nitrogen gas-charged, twin-tube design: built with the same OE-quality components KYB supplies to its global OEM products.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific, hand-assembled damping valves: manage tire contact, steering response, and body movement.
- Helps keep Electronic Safety Systems performing as designed: those systems depend on suspension, brakes, and tires working as the manufacturer intended.
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.
