I bought the SumoSprings because my truck has a harsh unloaded ride, but mostly because I have a truck box camper and the rear sag and tipsy feeling didnt make it a very confident drive. Researching options (air bag vs overload springs vs SumoSprings) for improvement led me here. Its a lot of money for rubber – doesnt appear to be anything special. Its not adjustable like air bags and frankly, i’ve never tried air bags to be able to make a comparison. The SumoSprings came with incorrect hardware for my truck – the Ubolts were not big enough to go around my axle. A quick run to HomeDepot for proper hardware and I was off to the races with a 30minute install. I was surprised to find that the two halves of the springs do not touch at all unloaded. Like – not even close – maybe an inch or so apart and so they do nothing until you load the truck. Dropping the camper into the box was much better, but there was still a noticeable sag – likely because they start so far apart to begin with. The ride improvement was now acceptable. So were they worth it? Final verdict – yes. My frustration is more with Ram than SumoSprings. The truck should be capable of hauling my camper without shelling out this kind of money. But after spending as much as I did for something so unimposing, to have it perform under expectations and to have to supply pieces of my own hardware only added to the frustration.
