I do have a solution, but your typical air bags and jounce-style springs for your lowered 2015 Ram 1500 will not work. I recommend using the Air Lift 1000 Universal Air Spring Kit - Rear like the # AL60917. In order to find the correct fit you will need to measure your rear coil springs.

First, unload your vehicle to make sure it's at normal ride height. Then, measure the inside height of your coil spring, which will be from the upper spring seat to the lower spring seat. Lastly, measure the inside diameter of the spring at its widest point. Once you have these measurements, use the table below to find the correct kit by matching up your diameter and height values.

Since the air spring cylinder will inflate, it's okay if the cylinder is slightly undersized compared to the size of the coil spring. The spring pitch will also indicate the total air pressure the bag should hold. This measurement is the distance between the coils. The bag can hold 50 psi if it is less than 1" and 35 psi if it is greater than 1". Additionally, some kits include spacers to make up for any height differences.

I have attached a helpful diagram which shows the measurements you need.
