Question:

Hi etrailer team. I have my 2023 RAV4 awd and double jet ski trailer. Im ok with the GWT specifications. When Im trailer jet skis and there is some issue in the road it feels like a vertical oscillating movement on the rear RAV4 suspension Average speed is 40MHP The jet ski are well balanced in the trailer. Im wondering if I install Timbren Suspension Enhancement System - Coil Spring Suspension - Rear Axle part no T58GR the vertical oscillating movement will be avoided or minimized? Thank-you

Hey Jose, is the trailer sitting level? Is there possibly not enough tongue weight on the trailer relative to the total weight of it? If the tongue weight isn't 10-15 percent of total trailer weight you will get sway. You will also get sway if the nose of the trailer is too high as well.

Suspension enhancement would not reduce sway so I would not recommend that.

Hey Jose, what ended up helping with the sway on your RAV4 when towing the jet skis? Sharing what you found could really help others trying to smooth out their trailer ride.
