Questions about this item

How often should the front left air spring on my 2013-2016 GL450 be inspected for replacement?

Unity recommends inspection during regular suspension service intervals; the rubber bladder and piston seal typically require replacement after extended exposure to road salt and temperature cycles.

What is the first limitation that appears when this air spring runs continuously under heavy load?

The rubber bladder reaches its maximum safe extension before the internal bump stop engages, limiting further axle travel.

Does the compressor run hotter or louder after installing this front left air spring on a 2015 ML350?

A properly sealed Unity air spring restores original system pressure, so compressor duty cycle and noise return to factory levels.
