I put the "inside coil spring" type on my 16 Ram 1500 4wd thinking I could save some money and still get okay capacity. They do okay for lighter trailers/loads. Have the full axle to frame bellow style airbags on my 71 Chev K20 and they are much better for towing heavier trailers/loads. I will likely replace the ones on my Ram next summer with the regular bellows style airbag.
