Monroe Shocks & Struts Suspension Shock Absorber P/N:37158
$68.99
Smooth out the ride and tighten up rear-axle control with the Monroe OESpectrum Rear Suspension Shock Absorber 37158. This OESpectrum light-truck shock is a direct-fit rear damper for the 1997-1999 Infiniti QX4 and 1996-1999 Nissan Pathfinder, designed to restore the vehicle's original factory drivability while filtering out impact-related noise, vibration, and harshness.
- Full displaced valving: tuned to the vehicle and paired with a larger bore for more efficient damping control, delivering a consistent, smooth ride over road extremes.
- PTFE-banded piston: provides consistent sealing between the piston and pressure tube for better control and increased durability.
- Twin Technology Active Control System: works to isolate impact-related noise, vibration, and harshness under most driving conditions.
- Nitrogen gas-charge: helps maintain tire-to-road contact by reducing aeration and shock fade, while OE all-weather fluid additives help resist oil breakdown in extreme temperatures.
A self-lubricating fluid seal retains gas and reduces friction against the piston rod to help limit premature wear. Sold individually; for balanced ride control, replace both rear shocks as a pair. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
