The KIA Sorento with larger size V6 engine can pull huge amount of weight. As previously stated 3,500 lbs or 5,000 lbs. This means its engine, transmission, drive system and chassis is rated for this MAX "towing" weight. It doesn't mean its "factory" suspension is made to support 10%-15% (average 13%) of loaded trailer's tongue weight. If it did, a solo driver will have too solid of suspension. Vision vehicle with solid axle and solid tires comfort at 100% of the time. Ouch!
For a vehicle with high towing lbs ratings, you'd think KIA would have optional factory towing package that included Air Bags, Air shocks or some other Rear Leveling systems - like other auto makers. re: Like Dodge and their Nivomat "load leveling" rear shocks.
In a perfect world, one can attach a Weight Distribution System with properly sized tension bars (on the attached trailer's tongue) and the vehicle's "stance" can be manually adjusted to level out. Yes. This is in a perfect world. In a reality world, not all trailers can accept a Weight Distribution System. In this case, install custom sized air bags within its coil springs, "air up" for heavy weight inboard cargo and/or trailer tongue weight and away you go. And if one cannot use a Weight Distribution system, remember NOT to exceed the trailer's hitch's non-WDS numbers. re: See Trailer hitch numbers for more details.
I wish Kia made optional Factory rear air bag systems for their Sorento V6 vehicles as well. But since they don't, one must go 3rd party - to customize the vehicle's rear suspension themselves. re:
"The Air Lift 1000 Universal Air Spring Kit (Part No: 60901) is a perfect fit for the 2016 Sorento LX V6 AWD". This product might fit for your year or Sorento as well....
Hope this helps.
5 out of 4 people have problems with fractions..... LOL!
