I install this on my 2010 Ram 2500 very simple and quick installation took 5 minutes with minimum tools used it over the weekend and hauled a 10000 pound load with about 3,500 pounds of tonge weight I had minimal sag in the truck rode very well... I went with this over airbags because my truck has a gooseneck hitch and it's also my daily driver so I did not want to compensate on my daily ride quality

I had high hopes for these little stops, but I'm having a hard time telling the difference. I regularly haul about 3,000 pounds of water (350 gal plus tank weight) in the bed of my RAM 2500 and was concerned about leaf spring compaction and handling. So instead of going the full pneumatic route I opted to replace the factory bump stops with these. Strangley, the passenger side unit seems to sit just a bit forward of the rear axle, while the driver's side one sits nearly top dead center (not exact, either). They were very easy to install (I didn't even need to jack up the truck), and overall I'm sure they will help out. The price was a little hard to understand, but after researching what was out there I landed on these as the best option.

I put an 11ft x 8ft bed on my long bed Ram and it has been squatting pretty bad when I pull a trailer. Now it doesn’t squat as bad and looks cool ðŸ‘ðŸ½Worth the money!And it was plug and play. Super easy to install!

The product itself good quality. This pic is my 2013 Ram 2500 with my 2021 Springdale travel on it. There is also a 1.5 inch sag in the suspension. With this said this Sumospring would never done anything to help the sag. I did contact the manufacturer and confirmed the part number.

Made my 1 ton dodge ride so much nicer pulling our 38ft 5th wheel camper

They work good. Put these on my one ton Dodge to help with my large horse trailer. Put some quality should on at the same time. Beats having to work about air pressure. Little pricey for what they are.

They were easy to install and worked as advertised. I'm constantly overloading the truck and this gives better handling under heavy loads

Easy to install and made a big difference in heavy load stability.

Old bolts for factory bump stops were seized. I had to cut the bolt heads off to remove the OEM bump stop. Unfortunately, the factory setup has anchor bolts welded in place with no way to remove them. I had to grind off the studs that were left, flush with the mounting pad and then drill new holes in the mounting pad and sumo spring pad in order to mount the sumo spring. I should say my dodge is a 2004 so there was a fair amount of surface rust that seized both bolts on each side. Nothing wrong with the Sumo spring although I have yet to load up my truck to see if the springs work as advertised.
