Perfect fit. No changes required. Drives smoothly. Changed left and right side. It is recommended to switch both at the same time for a smooth, balanced ride. These airbags were expensive compared to other products on the market, but felt solid. Hope it lasts longer. The time will show. Created by Dorman and sold to Revain. Arrived on time with first class delivery. Buyers make sure to buy the correct part - driver side and/or passenger side as one of them will not work on the other side with these airbags and also if you want to replace front or rear. So far, so good. Course changed!
