Smooth out every mile and keep your rear tires planted with the Monroe OESpectrum Suspension Shock Absorber 37408, a direct-fit 2020-2026 Toyota Highlander shock absorber that installs in the rear position. This OESpectrum light-truck unit is tuned to filter out noise, vibration and harshness while helping restore the vehicle's original factory drivability and ride control.
- Vehicle-tuned valving: Full displaced valving is tuned to the vehicle and adjusts to road extremes, while a larger bore delivers more efficient damping control for a smooth, consistent 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 for improved ride and handling.
- OE all-weather fluid: Contains special additives to help handle extreme temperatures and reduce oil breakdown, and a self-lubricating fluid seal retains gas while reducing friction against the piston rod.
Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee. Sold individually; replacing both rear shocks together as a matched pair is recommended for balanced ride control.
