Question:

Hello there, I have an all aluminum 6x10 cargo trailer that weighs 1,000 lbs dry. Loaded up with a motorcycle 2 spare tires and very minimal gear I am conservatively 1650 lbs loaded. I have a 2015 Santa Fe Sport 2.0T that is my tow vehicle. It squats my car about 3/4inch to an 1inch and I want to level the car for expressway driving. Do you have a light duty setup that may work for my application ? Tongue weight on the vehicle is about 220 lbs. Thank you

Expert Reply:

I have a couple options for your 2015 Hyundai Santa Fe Sport. First is the Coil SumoSprings Custom Helper Springs # CSS-1125R which will increase the stiffness of your springs by 30%. This will help to reduce the sag you are experiencing both with trailers and if you load heavy objects into your Hyundai.

For a more adjustable system you can look at the Firestone Coil-Rite Air Helper Springs # F4170. These will allow you to adjust the air pressure in your springs so you can dial in your ride height as well as ride quality. Since they are adjustable you will not lose your unloaded ride quality. You can also add a Compressor System # F2610 to be able to adjust the air pressure from your smart phone while you drive.

A weight distribution hitch like the Fastway e2 Weight Distribution # FA92-00-0450 will help to level your suspension but you will likely not need the sway control since there is not a large surface area on your trailer for winds to cause it to sway. If you feel this is still the best route you will need a 2" Ball # 40038 and 1-1/2" Socket # ALL643210.
