Direct-Fit Replacement

This Unity rear air spring carries part number 15-517700 and is engineered as a direct replacement for the 2011-2018 Jeep Grand Cherokee. It restores the factory air suspension system to provide a safe and comfortable ride. The component is manufactured by Unity, a brand with over 50 years of aftermarket experience.

Upgrade From Failed Units

The spring replaces an original unit that has developed leaks, cracking or compressor over-cycling. The jump is worth it when the vehicle sits unevenly, rides harshly or the dashboard suspension warning illuminates. Unity’s Elite Suspension Line is designed for trouble-free installation and long-lasting reliability.

Sustained Load Behaviour

Under continuous loading the air spring maintains consistent ride height and damping characteristics without fading. The design withstands repeated compression cycles and road-induced heat buildup during extended journeys. Unity’s manufacturing focus aims to keep the suspension performing reliably over the vehicle’s remaining service life.
