Monroe Shocks & Struts Suspension Shock Absorber P/N:5637

Smooth out the ride and keep your tires planted with the Monroe OESpectrum Shock Absorber 5637, a rear-position damper that drops in as a direct-fit replacement for the 2007-2018 Nissan Altima (see the Buyer's Guide tab for engine-level applications). Designed to help restore the vehicle's original factory drivability and handling feel, it works to control body motion while filtering out noise, vibration and harshness.

• Twin Technology Active Control System: delivers control under most driving conditions while isolating impact-related noise, vibration and harshness.
• Full displaced valving: tuned to the vehicle and paired with a larger bore for more efficient, consistent damping 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 & all-weather fluid: helps maintain tire-to-road contact by reducing aeration and shock fade, with additives that assist in extreme temperatures.

A self-lubricating fluid seal retains gas and reduces friction against the piston rod to help limit premature wear. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee. Sold individually — this listing is for one unit; replacing both rear shocks together as a matched pair is recommended for balanced ride control.
