Monroe 73048 OESpectrum Rear Strut Nissan Armada Infiniti QX80 14-19 QX56

• Monroe is the most recognized name in replacement shocks and struts for a reason — consistent quality, OE-grade engineering, and parts designed to the vehicle specification rather than a generic fit. The OESpectrum 73048 isn't a budget strut with Monroe branding; it's Monroe's direct OE-replacement tier.
• Acceleration Sensitive Damping means this strut automatically adjusts between soft (for comfort) and firm (for control) based on how fast the suspension is moving. You get a smooth highway ride AND confident handling in corners and emergency situations — without choosing between them.
• A worn rear strut on a QX80 or Armada means excessive body roll, longer stopping distances, uneven tire wear, and a ride that feels nothing like the truck you bought. The 73048 restores the factory behavior. Don't keep driving on worn suspension — especially in a full-size SUV.

Monroe's OESpectrum line. Part number 73048. Factory ride quality restored for your Armada, QX80, or QX56.

The Monroe OESpectrum 73048 rear suspension strut is engineered as a direct-replacement for the Nissan Armada (2017–2019), Infiniti QX80 (2014–2019), and Infiniti QX56 (2011–2013). Monroe's OESpectrum line is designed to match or exceed the original equipment performance specification — not just approximate it. Acceleration Sensitive Damping (ASD) technology adjusts the damping force in real time based on the speed of suspension movement, providing a smooth response over gentle bumps while controlling excessive body motion during hard cornering or emergency maneuvers. The chrome-plated piston rod and bronze-reinforced rod guide extend service life beyond standard replacement struts, and OE all-weather fluid maintains consistent performance across extreme temperature ranges. This listing is for a single rear strut (fits either left or right position).

KEY FEATURES:

•       Acceleration Sensitive Damping (ASD) — Monroe's ASD technology uses a hydraulic pathway that responds differently based on how fast the suspension is moving. Slow, gentle inputs (highway cruising) produce a soft, comfortable ride. Fast, harsh inputs (potholes, emergency swerving) trigger firmer damping for maximum vehicle control. The system operates passively — no electronics, no sensors, no programming required.

•       Tuned Rod-Displaced Valving — The internal valving is calibrated specifically to the Armada/QX80/QX56 platform weight and suspension geometry. This isn't a universal strut adapted to fit — it's tuned for these vehicles specifically, filtering out road noise and vibration transmission into the cabin that worn struts allow to pass through.

•       Chrome-Plated Piston Rod — The piston rod surface is hard chrome plated, creating a wear-resistant barrier that extends the working life of the seal and rod guide beyond what standard mild-steel rods provide. The result is a longer service interval before the strut begins to leak or lose damping effectiveness.

•       Bronze-Reinforced Rod Guide — The rod guide — the component that the piston rod slides through — is reinforced with bronze for lower friction and better alignment retention over the strut's service life. Reduced friction means more precise damping response throughout the stroke.

•       Nitrogen Gas Charge — A pressurized nitrogen charge keeps the oil aerated and the damping consistent across rapid successive compressions (washboard roads, speed bumps in sequence). Nitrogen prevents oil foaming that causes temporary damping fade in non-gas-charged units.
