Best leaf spring set up for towing?

So I have a 2015 tacoma with bilstein 5100 set at 2.5" lift and a 1.5" AAL. My truck was pretty leveled when first installed but I am pretty frequently towing my 18ft boat with it and now sags even when nothing is in the bed. I want to install a whole new leaf pack to get my truck to sit level or have a little bit of rake when nothing in bed or towing, but still have the durability to tow. I though about just going for heavy duty springs but it seems like most of the heavy duty springs will give me closer to a 2.75-3 inch lift which I feel like is too much for having a 2.5" lift in the front. Any suggestions on what I should do?

 

I’d look at air bags for towing. Firestone ride rite. I used them when I towed a trailer and they are great because you can adjust them when needed. I’m sure others will chime in on the lead pack

 

Airbags with Daystar cradles or a fullsize truck.

 

OME Dakars would be an improvement

 

Does the airbags add any ride height when not inflated?

 

No it won’t

 

After doing some research, I am thinking about maybe trying out the dobinsons leaf springs and maybe air bags with that. Any thoughts?

 

Sump Springs, maintenance and worry free once installed.

 

I think the key word is "now sags," implying it didn't before. If your unloaded,unhitched height changed, fix that first. Then look into trailer aids afterward. Don't use trailer aids to fix sagging springs.

 

I missed that point. Definitely time for some new leaf springs.

Then get a set of Sumo Springs.

 

What's the tongue weight on your trailer?

I'd recommend a new leaf pack and using a WD hitch when towing. Airbags are a payload solution and not the best option for towing (they don't shift any load off the rear axle of the tow vehicle).

 

Get some sumo springs and call it a day.

 

Okay so I think I will start by upgrading leaf pack. I think I’m gonna go with dobinsons. Should I get the lightest duty one rated for 0-200 constant weight because when I’m not towing I don’t really have anything heavier than that in the bed?

 

Sounds like that's the right pack for you @wolfwertheimer

 

This.
I have been running airbags for years and wheel with them deflated. Super flexy and never had a problem with them.

 

I'd go with whatever spring pack you think will get you the ride height you want with your most common bed load weight. Then get the airbags for trailering.
