It is a kit for the front, covering the left and right positions, so both front dampers are replaced together.

Which Ram 1500 years does it fit?

Mopar lists it for 2011 through 2018 Ram 1500 trucks. Check your build code against the listed codes before ordering.

Yes. 68040882AE supersedes 68040882AD, 68040882AB and 68040882AC, so it is the current revision of the same part.

It keeps the factory damping and ride height. Aftermarket shocks may be firmer, softer or adjustable, but this kit restores the original setup.
