Refresh your front suspension with the KYB strut cartridge 366004, a nitrogen gas-charged replacement damper that drops into the front struts of the 1988-1996 Buick Regal, 1990-2001 Chevrolet Lumina, 1995-1999 Chevrolet Monte Carlo, 1988-1997 Oldsmobile Cutlass Supreme, and 1988-1996 Pontiac Grand Prix. See the Buyer's Guide tab for engine-level fitment.
Part of KYB's Excel-G line, this is a twin-tube, gas-charged cartridge built to help restore the ride control, stability, and handling the vehicle was engineered with — calibrated to bring back the original designed performance rather than change it. That focus earns Excel-G its OEA (Original Equipment for the Aftermarket) classification.
- Triple-lip fluid seal: designed to reduce the chance of oil and gas leaking out.
- Hand-assembled damping valves: vehicle-specific valving works to manage tire contact, steering response, and body movement.
- Strong strut bodies and brackets: KYB uses thick bodies and brackets to minimize flex and help maintain correct alignment.
- Supports electronic safety systems: helps keep systems that rely on the suspension, brakes, and tires performing as designed.
To reduce the chance of noise and vibration, KYB recommends installing new strut mounts (part number SM5568) and protecting the cartridge with a KYB Strut Boot (part number SB104).
