Smooth out worn-out handling with the Monroe OESpectrum Suspension Shock Absorber 37301, a rear shock absorber for the 2004-2020 Toyota Sienna. This OESpectrum unit is a direct-fit rear replacement for the 2004-2020 Toyota Sienna, designed to restore the vehicle's original factory drivability while filtering out impact-related noise, vibration and harshness.
A self-lubricating fluid seal retains gas and reduces friction against the piston rod to help limit premature wear. If a worn rear shock is the cause of your vehicle's bouncy, unsettled ride, this unit replaces it. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee. Shocks work best replaced as a matched pair; this listing is for one.

This part cross-references / interchanges with the following part numbers:
Will this shock absorber fit a 2004-2020 Toyota Sienna?
Yes. The Monroe OESpectrum 37301 is a rear shock absorber cataloged as a direct-fit replacement for the 2004-2020 Toyota Sienna. See the "Vehicles it fits" section to confirm your exact vehicle.
Is the 37301 a front or rear shock absorber?
It is a rear suspension shock absorber.
How many do I need?
This listing is for one shock absorber. Shocks are best replaced as a matched pair, so ordering two for the rear axle is recommended for balanced, even ride control.
What does the PTFE-banded piston do?
The PTFE-banded piston provides consistent sealing between the piston and pressure tube, which Monroe states delivers better control and increased durability.
Why is it nitrogen gas-charged?
The nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade, which supports a more consistent ride and handling.
