How to keep a TRD Pro from squatting while towing?

Sumo Springs do not affect the unloaded ride. The frame doesn’t rest on the sumo springs unless you have load or hit massive bumps. They are progressive so very soft on smaller bumps and become stiffer as they get compressed more. They do affect articulation on serious flexing but should not have any detrimental effect on mild off roading.

 

I get that... the picture you posted was just for illustration. But someone suggested that the boat in the OP isn't situated correctly on the trailer due to the level of sag in the 2nd gen pro, and I think that is a bit unknown because there's a dude in the bow of the boat.

I'm sure the poster just missed the guy in the front of the boat before making his assessment (and I wasn't trying to "get him" in anyway). I know shit about how to mod for avoiding sag, but wanted to point that out because this is an interesting discussion that I'm following along with.

 

Part number for Pro leaf springs from 11/17 is different from the "firm" and "standard" spring part numbers.

 

The part number on my 17 Offroad springs were the exact same as the part number On my buddy’s 18 pro.

 

I bought my firestone air bags for about the same price as the sumo springs. Also I know one day the stock springs will start to sag and I believe will begin to ride like chit from the resting on the sumo springs....?

 

Maybe until manufacturing date of 11/17. I think they probably just fixed the squeak, though.

Get a better leaf pack that can handle heavier loads.

 

Just ran across this (it is from 2014) so things may have changed but it makes me want to do a little more research on the Daystar Cradles.

Unless you are lifted, you shouldn't need the cradles. But tons of people use them, and I'm sure the lawyers at Firestone just did that to CYA.

 

That was my thought also, releasing them from liability.

 

This is exactly why I didn't get the cradles. Lots of people doing it with success, but still not worth it to me.

 

Here is the ultimate answer for this post (in no particular order) :

1. New HD leaf springs will support more weight than stock and still sag a little when adding weight

2. Air bags will support more weight than stock and will allow you to adjust ride height.

3. Adjustable resivour shocks will allow you to have a comfortable ride with different weight scenarios.

And don't forget the weight distribution on the entire truck. Even if you add all of these parts, you can only put so much weight on the back of this truck before there isn't enough weight at the front wheels to handle safely.

 

Firestone Ride Rite airbags.....I have had them for 6 years now. work great. Easy to adjust for various loads

 

Ask how many people had an issue with them, vs others who haven’t. I saw one post here, no others.

 

Not a turdPro but I run the Sumosprings and they have been great... this pic was from last weekend, trailer tanks mostly full so probably around 3k lbs and a load of camping/climbing gear and another mtb in the bed. However, even unloaded (with my topper) my sumosprings contact the frame which I don't love. I took the topper off this summer and they don't touch unless there is a load in the bed. There is a slight difference in ride, only noticeable with the topper on since there is some contact but I actually prefer it as it feels like it stiffens the rear up a little bit. I was even tongue heavy here and there is zero squat.

I don't do any crazy offroading but more than the average person, and lots of shitty dirt road travel - handles it all just fine, just a little less articulation I suppose.

I plan on getting better springs eventually, but this has been a must have for me. They are super easy and quick to put on so it's a good starting point I think.

 

No, bro. “Resi” adjusters are to fine tune ride comfort, not to keep a truck from squatting from a heavy load.

 

Thanks for using mudflaps. Yeah, airbags would be my first choice, cheap, easy, and versatile.

I'll mention this just because I like typing Hellwig. https://www.suspensionconnection.co...MIr9-ei8CT3gIVWbbACh2zPg95EAQYASABEgLVfPD_BwE

 

My Firestone Ride Rite Air Bags were first bought and installed by Off Road Warehouse (Escondido, CA) on my 2005 DC Off Road 4x4 to stop the bottoming-out from the weak rear springs (my dealer refused to check with the factory, which later announced the Harsh Ride TSB).

They worked perfectly... I could add or remove air to set the level of my truck and no more bottoming at every speed bump with a load in my truck (two people in the back seat caused it to bottom).

When I traded up to a 2010 (also a DC TRD Off Road 4x4), I had the dealer remove the air bags in case the new Tacoma also bottomed-out. Well, the new springs were better (still a 3-pack) and it didn't bottom with a load, but after a few years the stock Bilstein shocks wore out so I upgraded to 5100s and had my air bags put on. This time Jason @speedfreek did the install and as before the air bags worked perfectly. I recently did some measurements, and that may be of interest to you?

Let me add, that the air bags have been driven thousands of miles in Baja California, Mexico and never any problem with them on either of my Tacomas over the past 11 years. So, they are BAJA PROVEN!

 

Use a weight distribution hitch and don't screw with the suspension you paid for.
