Rear Helper Spring Question

Looking for information on a rear helper spring kit for my 2010 Tacoma DCSB Sport model. I am pleased with the way it rides now, but when I hook my 18ft bass boat to the truck the ass-end sits lower tan I'd like.

Dips and bumps cause the rear to drop quite a bit more. Sometimes even feeling like its almost hitting the bump stops.

Any recommendations on a spring kit to alleviate this issue?

TIA

What year is your Tacoma? There is a TSB (Technical Service Bulletin) for the weak leaf springs in the Tacoma. It's covered under the 3 yr 36k mile warranty. If you're out of that, you might want to consider either air bags or Timbrens. Timbrens are basically a taller bump stop that has some give to it and acts as a support spring without the air hoses associated with air bags.
