Keep the rear of your truck planted and filter out impact harshness with the Monroe OESpectrum Suspension Shock Absorber 37251, a rear-position light-truck shock. It installs as a direct-fit replacement for the 2004-2015 Nissan Titan and the 2016-2024 Nissan Titan XD — see the Buyer's Guide tab for engine-level fitment. Monroe OESpectrum shocks are designed to restore a vehicle's original factory drivability and control while isolating impact-related noise, vibration and harshness.
A self-lubricating fluid seal retains gas and reduces friction against the piston rod. Sold individually — replace the rear pair together for balanced ride control. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.

What vehicles does the Monroe 37251 shock fit?
It's a direct-fit rear shock absorber for the 2004-2015 Nissan Titan and the 2016-2024 Nissan Titan XD. Check the Buyer's Guide tab to confirm engine-level fitment for your vehicle.
Is this a front or rear shock?
It is a rear-position suspension shock absorber, as listed in the catalog.
Does one listing cover both sides?
No. This shock is sold individually. For balanced ride control, it's best to replace the rear pair together as a matched set.
What are signs my shock may need replacing?
Common signs include excessive bouncing over bumps, nose-diving when braking, uneven tire wear, or fluid leaking from the shock body. Have the suspension diagnosed to confirm the cause.
What does the nitrogen gas-charge do?
The nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade, which supports more consistent ride and handling.
