Restore the designed ride control, stability, and handling on your Asian SUV or Crossover with the KYB Excel-G Suspension Strut (MPN 340085), a nitrogen gas-charged, twin-tube front strut. It installs as an Original Equipment replacement for the front suspension on the 2017-2023 Lexus GX460, 2010-2024 Toyota 4Runner, and 2010-2014 Toyota FJ Cruiser — built on the same KYB OE assembly lines with the same OE-quality components and calibrated to restore original, designed performance rather than change it, earning its OEA (Original Equipment for the Aftermarket) classification.
- Nitrogen gas-charged twin-tube design: includes every quality component found in KYB's global OEM products, and is a choice preferred by professional technicians.
- Triple-lip fluid seal: designed to reduce the chance of oil and gas leaking out.
- Strong, thick strut bodies and brackets: help minimize flex to maintain correct alignment in all conditions.
- Vehicle-specific, hand-assembled damping valves: tuned to manage tire contact, steering response, and body movement.
Because electronic safety systems depend on the suspension, brakes, and tires working as the manufacturer intended, the Excel-G helps keep those systems performing as designed. Sold individually; replacing both sides of the axle as a matched pair is recommended for balanced control.
