Restore your vehicle's original ride control, stability, and handling with the KYB Excel-G Suspension Strut 234039, a nitrogen gas-charged, twin-tube gas strut that installs as a direct-fit rear right replacement for the 1991-1996 Ford Escort, 1990-1994 Mazda 323, 1992-1995 Mazda MX-3, 1990-1994 Mazda Protege, and 1991-1996 Mercury Tracer. KYB builds the Excel-G on the same OE assembly lines it supplies to new-vehicle manufacturers, calibrated to restore the suspension's designed performance rather than change it — earning it the OEA (Original Equipment for the Aftermarket) classification.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand assembled in-house to manage tire contact, steering response, and body movement.
- Robust strut body and brackets: KYB's thick strut bodies and brackets help minimize flex to maintain correct alignment.
- Supports safety systems: helps keep electronic safety systems performing as designed, since they depend on the suspension, brakes, and tires. Made in the USA.
KYB recommends installing new strut mounts (part number SM5046) and a KYB Strut Boot (part number SB118) to help reduce noise and protect the strut from dirt, debris, and salt. Struts wear as a pair, so replacing both sides together is recommended for balanced handling.
