Updated 12/03/2025 | Published 12/02/2025

Question:

Im looking to beef up my rear suspension. I use my KIA Sorento as a work vehicle and travel up and down the east coast. When loaded it has a bit of sag. Any suggestions ?

Hi Matt, welcome back! The Coil SumoSprings # CSS-1125F are only for the front axle on your 2022 Kia Sorento. However, that doesn't mean SuperSprings doesn't have one that will fit. If you can measure the gap between the middle of the coil on your rear coil springs I can find the right size. You do not need to lift it, just measure the gap as it sits.

The drivers side is 3/10 of an inch under 1 inch and the passenger side is 3/10 of an inch over 1 inch

@MattH is that on a level surface with nothing in it? They should be roughly the same unless something wore out one side over the other. A 0.6875" - 0.875" coil gap would be # CSS-1094 and a 1.25" - 1.375" coil gap would be # CSS-1145. The # CSS-1125 falls in between for a .9375" - 1.1875" coil gap, these are the same ones confirmed to fit the front coil springs on your Sorento.

It is sitting on a slight incline and nothing is in the Sorento. Do you think the CSS-1125 will work?

@Matt I would try to measure it as level as possible but yes, the # CSS-1125 will likely work.
