These were replacements for the one that failed at the groove above the spring after ten years of rough use. Easy to install, just spray with some alcohol to make slippery and press in place where the original bump stop was.

Springs are easy to install & work very well compared to my OEM bumpers I had on a 2022 Thor Vegas RV.You Notice the difference when encountering rough roads.Overall a good purchase N they work as advertised.

Great for beaches and washboards. These take the sting out of the bumpstops. If you often drove on the sand or bottom out your bump stops at speed, these are ell worth the money

Took those before going with hydraulic bumps, they are better on soft offroad driving than stock bumb stops.. but on harsh bottoming the act almost still the same way as stock ones, but for the price they are good

Seriously, super easy replacement. You literally reach up and pop the old bump stock out. To install the sumo springs, use a little soapy water in a spray bottle and coat the top of the spring and the inside of the cavity where you’re going to put it in. It can take a little bit of strength to get it popped in, but it really is not too bad. Just got back from the Uwharrie National Forest Jeep trails. I’d like to think that it made a difference. :-) See pictures for reference.

These were a little expensive for what they are, but they're made well and do a good job. Much less of an investment than the King hydraulic bump stops I have up front, although those are a whole different technology and are fantastic.

I loaded a pallet of concrete on my trailer and had minimal squat in the rear of my jeep. Like everyone has said, these do not make up for incorrect spring rates, they are simply helpers.
