Question:
I have a 2021 toyota highlander xle. when I tow my trailer, the back sags about 2 inches. I wouldnt want to install a towing bar kit, because my trailer weighs only 3000lbs once loaded, the antiswing does the job well. I was wondering if Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Front or Rear Axle CS1145 would do the job and it wouldnt damage my vehicle for toyota warranty.

Expert Reply:
Yes, the Coil SumoSprings Custom Helper Springs # CSS-1145 will help prevent the sag you are experiencing. These will provide additional support and use progressive load control so they get stiffer as you add more weight. The # CSS-1145 will work for the AWD model. If you have the FWD model then you can use the # CSS-1125 instead. Proper installation of the SumoSprings will not damage your vehicle or void the warranty.
