Sway Prevention for Jayco Jay Flight SX7 Towed By 2020 Ford F150

Question:

When I tow my 1-year old Jayco Jayflight SLX7 travel trailer with my 2020 Ford F150, I have a bad sway problem. What can I do? I'm afraid to tow it. Would helper springs or Timbren springs help?

As kind of a rule of thumb, suspension enhancement like helper springs or Timbren Aeon springs are most effectively used to suspend loads carried in the truck bed, but they're not the best choice for suspending a trailer's tongue weight.

For instability caused by a trailer (or more specifically, crosswinds and turbulence from oncoming or passing traffic acting on the trailer), a weight distribution system that's been properly tailored to the as-towed tongue weight of your Jay Flight SLX7 will do a much better job of combating trailer sway than a suspension enhancement product.

According to my research, the GVWR of your Jay Flight SLX7 is around 3750 lbs, so your maximum tongue weight will be 10-15 percent of that figure, at the heaviest. Given that, you'll need a system rated for around 550 lbs of tongue weight at the most.

I really like the Equal-i-zer system which combines reliable weight distribution with proven trailer sway control. The system is manufactured in the US and is backed by a lifetime warranty. Given the estimated tongue weight you'll have, I'd recommend the Equal-i-zer # EQ37061ET system which is rated for trailers with tongue weighs ranging from 200-600 pounds.
