Everyone knows the E53 has been notorious for the air ride system to fail. Even BMW technicians will tell you it's not if your air bags will fail, its when. Repairs can become fairly costly as well, with each bag plus labor potential costing you hundreds and hundreds of dollars. Not only that, but the repairs never seem to be permanent, whether its a sensor going off a leaky air bag or the compressor. Get rid of these problems for good, with this Coil Spring conversion kit. Using OEM springs will give you similar ride height as the air ride without compromising handling or comfort.

**Note: Installing this kit will trigger a Self-Leveling Suspension Inactive Light**
