Smooth out the ride and keep the rear tires planted with the Monroe OESpectrum Rear Suspension Shock Absorber 37243. This is a rear-position light-truck shock designed to restore the vehicle's original factory drivability and ride control, and it installs as a direct-fit replacement on the 1998-2003 Toyota Sienna. See the Buyer's Guide tab for full application details.
- Full displaced valving: tuned to the vehicle and paired with a larger bore for more efficient damping control, adjusting to road extremes for a smooth, consistent ride.
- PTFE-banded piston: provides consistent sealing between the piston and pressure tube for better control and increased durability.
- Twin Technology Active Control System: delivers control under most driving conditions while isolating impact-related noise, vibration and harshness.
- Nitrogen gas charge: helps maintain tire-to-road contact by reducing aeration and shock fade, while OE all-weather fluid resists breakdown in extreme temperatures.
A self-lubricating fluid seal retains gas and reduces friction against the piston rod to help limit premature wear. Signs your rear shocks may need replacing include excessive bouncing, nose dive, body sway, or fluid leaking from the shock body. Backed by Monroe's Limited Lifetime Warranty.
