Hitch and Weight Distribution System Recommendation for a 2010 Toyota Highlander Towing a Trailer


I have a 2010 Toyota Highlander AWD 500/5000 , Im towing a 16ft hybrid 350/2700. The rear of the vehicle sags about 1 1/2 inches when loaded. I bought the curt class III hitch 500/5000 thats not rated for a WD hitch didnt do my homework on that one. Could I safely put a WD using this hitch or would to be best to use the SuperSprings to just help the suspension from sagging. The tow vehicle drives and steers fine as is, just looking to level everything out. Thanks,

The best possible solution I could recommend for you is probably one you don't really want to hear. I would recommend you install the Hidden Hitch part # 87452 on your 2010 Toyota Highlander after removing the Curt hitch you have since this hitch is rated for weight distribution systems.

Suspension enhancement systems like the Coil SumoSprings part # CSS-1145R are not designed for trailer applications. These systems are designed to provide support for heavy loads in the rear of the vehicle. When used in a trailering setup they actually act as a fulcrum point and unload the front axle of the tow vehicle which affects braking and handling.

The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow, this figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached an FAQ on determining tongue weight for you to check out as well.

If 350 lbs is your loaded tongue weight I would recommend the Reese Weight Distribution System # RP66540 since it has a tongue weight range of 300-600 lbs.
