Help smooth out every mile in your truck with the Monroe OESpectrum Rear Suspension Shock Absorber (37251), engineered to help restore original factory drivability and ride control. It installs as a direct-fit rear replacement for the 2004-2015 Nissan Titan and the 2016-2024 Nissan Titan XD.
- Exceptional handling: Full displaced valving, tuned specifically to each vehicle, adjusts to road extremes, while a larger bore provides more efficient damping control for a consistent, smooth ride.
- Control and durability: A PTFE-banded piston maintains consistent sealing between the piston and pressure tube for better control and added durability.
- Reduced noise, vibration and harshness: The Twin Technology Active Control System is designed 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 for improved ride and handling.
OE all-weather fluid carries special additives to assist with temperature extremes and help reduce oil breakdown, and a self-lubricating fluid seal retains gas while reducing friction against the piston rod. This is a rear shock; replacing both rear shocks as a matched pair is best practice for balanced ride and handling. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.

Frequently Asked Questions
Is this the right Titan absorber for a 2004-2015 Nissan Titan or 2016-2024 Nissan Titan XD?
Yes. This rear shock absorber is a direct-fit replacement for the 2004-2015 Nissan Titan and the 2016-2024 Nissan Titan XD. Check the "Vehicles it fits" section to confirm your exact vehicle.
Is this a front or rear shock?
It is a rear suspension shock absorber.
Should I replace both rear shocks at the same time?
Replacing both rear shocks as a matched pair is best practice for even, balanced ride and handling. This listing is for one shock, sold individually.
What are the signs a shock may need replacing?
Excessive bouncing after bumps, nose-diving, a harsh or unstable ride, uneven tire wear, or fluid on the shock body can be signs. Diagnose the cause before replacing, since other parts can produce similar symptoms.
Is this shock gas-charged?
Yes. It uses a nitrogen gas charge that helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
