Unity Rear Air Spring 15-512800

This rear air spring replaces the original air suspension unit on select Mercedes-Benz R-Class models from 2006 through 2013. It restores ride height and load-leveling function for daily driving or towing use.

Replaces worn or leaking factory air springs

The jump is worth it when the original air spring develops cracks, loses pressure or triggers suspension warning lights. Unity manufactures this unit to match OE fitment for the R320, R350 and R500 across the listed model years.

Direct bolt-on installation with basic tools

No modifications to the chassis or air lines are required. Common issues include reusing old mounting hardware that may be corroded and failing to bleed the air system properly after fitting the new spring.
