Unity Rear Shock Absorber Kit

The Unity rear shock absorber kit supplies two nitrogen gas charged twin tube units built as direct replacements for the original equipment on 2011-2015 Dodge Durango and Jeep Grand Cherokee models. Installers receive both sides in one package, reducing the chance of mismatched damping on the same axle.

Thermals noise and power draw

Suspension dampers convert kinetic energy into heat through hydraulic fluid and nitrogen gas, so they run at ambient under normal driving and produce no audible noise or electrical load. The sealed twin tube design maintains consistent damping without external reservoirs or adjustment mechanisms.

Vehicle fitment decides suitability

This kit fits only the 2011-2015 Dodge Durango and 2011-2015 Jeep Grand Cherokee listed in the application data. Vehicles outside those model years or different platforms require a separate part number and cannot use these shocks.

Questions about this item

How do I install the twin-tube nitrogen gas charged shocks on my 2011-2015 Dodge Durango?

Remove the old shocks, then bolt the new Unity units to the factory mounting points using the original hardware; the step often missed is torquing the upper and lower bolts to the vehicle manufacturer's specification.

What maintenance or replacement will the nitrogen gas charged shock absorbers need later?

Inspect for oil leaks and worn bushings at each service interval; the gas charge cannot be recharged, so replace the complete shock absorber once damping fades or fluid appears on the body.

What limit appears first under sustained use on these rear shocks?

The nitrogen gas pressure and hydraulic fluid degrade with heat cycling, so fade during repeated heavy loads or towing is the first performance limit you will notice.
