Suspension Enhancement Availability for a 2012 Toyota Highlander Using Weight Distribution

Question

Question:

Hello, I am looking for something to help balance out my 2012 Highlander. I pull a 4400 lb travel trailer and notice some rear end sag even with weight distribution bars on. The handling of the Highlander is fine, Im just looking for something to level it out a bit more. Would you recommend the CSS-1145R, or should I look at something more substantial? Thank you for your help!

A properly setup weight distribution system should all but totally eliminate the rear end sag of a vehicle when towing. I would first make sure you have a setup that is properly rated for the tongue weight of your trailer and that it is also properly setup. With those two things check out you should see the trailer setting as level as possible.

If you still need some suspension support the part # CSS-1145R has been confirmed as a fit for your vehicle and would help prevent rear end sag.

I attached a help article on determining tongue weight for you to check out as well.

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…
