Suspension Enhancement Recommendation for 2025 Kia Telluride Towing Keystone Coleman 13B

Question

Question:

I drive a Kia Telluride 2025 EX and tow a 2025 Keystone Coleman 13b dry weight 2400. I am looking for an air bag or easy to install airbag, coil support or something to reduce sag and help with my suspension, as the weight distribution hitch does not work well with my whole body frame. Would this part work well or do you have any other suggestions? I would like something low maintenance, and we do a 2000 mile trip once a year, if that matters.

Hey Amanda, we can definitely help! I would recommend the SumoSprings kit part # CSS-1125R for your 2025 Kia Telluride to get rid of the sag when you are towing. This requires zero maintenance unlike the air bag kit part # AL29PD that fits your vehicle while also providing great support and an easier install. How much sag are you getting now do you think?

Several years ago, I ordered the rear sumo spring for my 2020 Chrysler Pacifica "minivan" specifically for towing similar weight on a trip out west (6,000 miles roundtrip) and to improve sag when it is loaded up pretty heavily. The Pacifica was designed with a softer spring that improves ride, but sagged noticeably under loads - either just camping equipment, trailering or both. I was shocked how well they worked eliminating sag. When not hauling camping equipment or trailering my pacifica's ride height was the same as before the coils were installed. After installation, the pacifica had a very slight increase in ride firmness, but nothing that changed the overall comfort or handling of the pacifica in any way. Actually, I like it better now and the coils are still installed during all my daily driving. The install was straight forward and not complex - don't forget to use plenty of dish soap on the coils so they slide easily onto your coils. I sort of pushed them onto the coils inch by inch in many small motions - not in one large motion. All my best, jb

I get a lot of sag, I haven’t hitched it up in about a year without the weight distribution hitch, but that hitch makes me life the RV in order to put the support bars in place and then it almost feels as though it’s lifting the back frame of my car and I know that is not good. It is my understanding, correct me if I am wrong that the weight bars should slide on when hooked up and you shouldn’t have to rise the RV a great deal to put them on. I want a system where i can just use a normal hitch for safety reasons and so I can turn without feeling like I’m breaking everything because the noise with the weight distribution hitch is awful

@AmandaP is it possible you are trying to use too much spring bar tension and that's why it feels like that? Or maybe is the system rated too high for your tongue weight? That said the noise is pretty crazy with WD systems!

@JamesonC I can’t even get the bars on without lifting the camper, I’m going to look at lowering the ball mount a smidge as well. Would this item work on the back springs? As that’s where the sag is but when I clicked on the link it said it was for the front springs.

@Amanda It's actually pretty common to use the trailer jack to lift the rear of the tow vehicle up to help get the spring bars on the system so that's not necessarily an indicator something is off. I did link wrong part number above. My apologies I should have linked # CSS-1125R.

Hey Rand, we have the Air Lift 10000 kit part #AL60825 that is a fit for your 2023 Jeep Grand Cherokee, is this what you meant by coil supports? These install inside the coils of the rear suspension.

Since the pin weight of your camper is 2.1k, I recommend going with the LoadLifter 5000 opposed to the 7500. While technically there is not reason you couldn't use the 7500 kit, it really is not necessary for a camper like yours. Generally the…
