Unity Rear Shock Kit for Nissan Armada

The Unity 255040 kit supplies two nitrogen gas-charged rear shock absorbers designed as direct OE replacements for 2005-2014 Nissan Armada and 2004 Nissan Pathfinder models. It is intended for owners restoring ride control on vehicles without automatic rear air leveling suspension. The twin-tube design targets drivers who want a straightforward, bolt-in solution for worn factory dampers.

Sustained load behaviour

The nitrogen gas charge helps reduce aeration and fade during extended driving, keeping damping force more consistent than non-gassed units under repeated compression cycles. The twin-tube construction dissipates heat through the outer reservoir, so performance remains stable on long descents or when carrying passengers and cargo. It is not suited for vehicles equipped with automatic rear air leveling suspension.

Installation notes and common fitment issues

The kit includes two shocks packaged together, simplifying a complete axle refresh with matched components. Installers should verify the vehicle lacks automatic rear air leveling before starting, as that system requires different hardware. No specialised tools beyond standard suspension sockets are mentioned, but seized lower bolts on high-mileage examples often add time to the job.

Questions about this item

How much power does the nitrogen gas charge add to the rear suspension on a 2005 Nissan Armada?

The twin-tube nitrogen gas charge restores factory damping control without drawing electrical power from the vehicle.

What tools or parts must I already have to install the 255040 kit on a 2004 Pathfinder?

Standard suspension hand tools and the vehicle’s original upper and lower shock mounts are required for a direct replacement.

Will these shocks work alongside the original front struts on a 2014 Armada without air leveling?

Yes, the kit is designed as a direct OE replacement for non-air-leveling models and pairs with existing front suspension components.
