I had previously received a set of these to put on our Ram 2500, these are a spare for later use. The first set works great to help with stability on the rear bed when we put the weight of our 5th wheel on the truck. There are other brands out there. these work great for our 5th wheel application.

Installed these springs on rear of 2018 Ram Promaster 1500. Really improved the handling and raised the rear about an inch. Can now navigate turns at higher rate if speed with less lean.

I installed these on my RAM Promaster 2500. Previously I had an air bag suspension, The air bags after several years developed a leak so I removed them and purchased these SSR-313-54 Helper Springs. The installation was very simple. I watched a lot of videos on Youtube. It took me about half an hour to remove the original air bag suspension and install the new one.Installed these Sumo springs. they raised the back end of my RAM Promaster almost 1"". The riding experience was beyond my imagination, Actually very firm like a stock new. I recently put a 200 pound load in the bed and the rear height of the RAM didn't move. I can easily handle a firmer ride, preventing swaying and do not regret buying these bump stops, Highly recommended!
