How to keep a TRD Pro from squatting while towing?

Ok. Definitely not relaxed and he asked, “how to keep a PRO from squatting while towing or when loaded down with camping gear etc”

 

What is your tongue weight?

 

@T4RFTMFW is correct though. Air bags while very good to help with sagging, are not really intended to support excessive tongue weight or 6,500lbs worth of a trailer alone. That is not their intended use.

And fancy ass off road adjustable shocks are not a cost effective suggestion.

If the OP does a lot of towing, I would plan on a new leaf pack at some point.

Yes.

The boat in the original post is actually loaded too far forward for the truck or a proper weight distribution hitch is not being used. That truck is sagging from excessive tongue weight (which on these trucks is I think 750lbs?)

That long bass boat is longer than the first boat and that engine is heavy and loaded far away. Which is great as long as its not pulling up on the hitch.
The vast majority of the weight of a trailer needs to be on the axle not on either the front or the back end of the trailer. Both are dangerous for handling.

 

Absolutely correct. More money than adding springs but far more adjustment possible for different loads.

If your plan is to violate the maximum tongue weight or the MCVW then you need a bigger truck not a new suspension.

 

I have airbags with an airlift 72000 controller. It is wonderful for towing. 5psi for commuting, 40-55 for towing boats.

I'm getting an AAL as a lift, I'll keep the airbags in and see how much I actually need them after the AAL.

 

The boat in the OP has a ~200lb guy in the bow that likely won't be there while towing.

 

Then the solution is - arrange your load correctly.

 

I put Firestone RideRites on mine, works great for dealing with a full load of camping gear, just deflate to 5 psi when unloaded. These things are tough, and unless you are lifted, it would be difficult to tear them up when flexing. They are designed to support the full weight of the axle. Sumo Springs are another decent option, but I have no experience with those.

This is just ignorant.

 

Adios.

 

This isn’t the suspension discussion? Sorry, wrong room...

 

Says the guy who modified his Toyota suspension?

If it was perfect without mods why did you add air bags?

I think you read my post incorrectly

 

Ok thanks for all the advice, I was hoping this would go longer than it did without the stupid back and forth childish CRAP that every post on this forum inevitably deteriorates into... but it didn't.

 

I did ask how does it ride unloaded

Good points, I will replace the leafs once I start adding some more permanent weight to the truck.

This will vary, ideally it won't exceed the max but I don't live in a perfect world either stuff happens and loads shift or sometimes you just have to haul more than you had planned or it was just loaded wrong and you have to make it work.

When at all possible this is an OK answer but again I live in an imperfect world and this is not always feasible.

 

Well, to be fair you did assume the pro has exclusive rear leaf springs, so the shit talk was inevitable

 

Well if it matters, I tow and put in a single Deaver AAL and air shocks. To preserve my off-road flexing, Im using Daystar cradles too. If you do install air shocks, don’t T the two lines together- air sloshes between them on corners and makes you lean the wrong way. I made a short equalizer hose with two quick air filler ends on it to perfectly equalize pressure between the two after I fill them up.

 

Actually, to be fair, I never did I assume that, in fact I knew for a fact they shared leaf springs with other models. Not sure where you got this idea. I just said it had "TRD Tuned" suspension soooo...

To be honest I also don't fall into the "Don't ever modify a Pro's suspension" camp, I think that is kind of ignorant honestly. Nothing is ever perfect and people re-engineer stuff all the time and it even works better a lot of the time.

 

I have air bags and think you would be happy with them. Just order up the daystar cradle to go with.
Black Friday and cyber Monday is coming up, wait and save.

 

fair enough, it also appears it does not have a drop hitch which could help in that particular case, I was mainly using that to show the squat I want to avoid. The trailer could have had a giant pink flamingo statue on it or anything else for that matter... Maybe something like this...

 

There is a huge difference between weight in the box vs. pulling a trailer. Weight on the hitch as mentioned above, is a center of gravity thing; i.e., the C/G weight should be over the trailer axle, not sitting on the hitch or over weighted rear of the trailer. No different than loading an aircraft...its CG!!! Out of CG one way or the other is DANGEROUS ! Your stock springs should serve satisfactory as long a recommended tow/tongue weight is not exceeded. The other question is the weight in the box, in which several recommendations above should suffice. Your choice.

 

Seems like air bags and sumo springs are best options. AAL or new leaf springs probably if you tow more consistantly.

It seems like most people use air bags as opposed to sumo springs...any reason why?

Any difference in terms of longevity between 2 and what's easier installation?
