Smooth out rear-axle impacts and help keep your Lexus planted with the Monroe OESpectrum Suspension Shock Absorber 37398. This rear shock is a direct-fit replacement for the 2012-2023 Lexus GX460 (see the Buyer's Guide tab for engine-level fitment). Designed to help restore the vehicle's original factory drivability and handling, it dampens suspension movement while filtering out impact-related noise, vibration and harshness.

  • OE all-weather fluid: contains special additives to assist with extreme temperatures and help reduce oil breakdown for a consistent ride.
  • Full displaced valving: tuned specifically to each vehicle and paired with a larger bore for more efficient damping control and a smooth ride.
  • PTFE-banded piston: provides consistent sealing between the piston and pressure tube for better control and increased durability.
  • Nitrogen gas-charge: helps maintain tire-to-road contact by reducing aeration and shock fade, while a self-lubricating fluid seal retains gas and reduces friction against the piston rod to help limit premature wear.

Twin Technology Active Control System works to isolate impact-related noise, vibration and harshness under most driving conditions. Backed by Monroe's Limited Lifetime Warranty and exclusive Feel the Difference Guarantee. Shocks work as a pair — replacing both rear units together is recommended for balanced, even damping.
