What is Best Way to Reduce Sag When Towing with 2015 Toyota Tundra
Question:
I’m always one of excess or overkill and don’t want to have the wife upset on her 2015 Tundra. I’m looking at the 2 sumosprings offered 1500lbs and 2800lbs. We tow a single axle trailer with a comp ski boat. It has a lot of tongue weight, when loaded I’m almost to the bump stops. I read one persons similar question on best between these 2. Watched the videos on both. Both videos showed a 1” sag when 1500 lbs installed wondering if same sumos 1500# for that portion of the video as he said they loaded 1500# on both?. I’m leaning towards the 2800lb springs as I don’t want the 1” sag. My question is will the UNLOADED ride change using the 2800# sumo? Also, is the 2800# overkill for my application? Thank You.

I understand what you mean by wanting to go above and beyond with your towing setup so that it's as safe as possible but also you don't want to ruin the ride quality of your wife's Tundra so I have what I feel is your best solution.
So instead of suspension enhancement your best solution is actually a weight distribution system. A WD system reduces sag like suspension enhancement but since it does so by moving some of the tongue weight of the trailer to the front axle of the tow vehicle you actually improve handling and braking quite a bit. Which is very helpful in the event of an emergency situation. And the other great benefit is that it improves the ride quality when towing and doesn't effect ride quality when not towing. So for a weight distribution system for a boat trailer you'd need a pole tongue adapter like # RP58393 so that you can use a system like # RP66542 and you'd be ideally setup. This has a tongue weight range of 600 - 1,200 lbs.
But if you did want suspension enhancement the best solution is the RAS system part # RAS4611TD which will give you adjustable rear suspension support you are wanting while also improving ride quality when towing and not towing. Unlike other options which will make the ride quality harsher when unloaded most report and improvement.
