Trailer makes my pro squat ridiculous....

@xj2202009, I have Toytec 1.5” shackles, they’re the gold colored things at the end of each leaf beside the spare tire. It physically raised the back and improved the ride due to the new and greased poly bushings, but I have a slight rake unloaded, level when pulling our 33TT.

The part that helps a lot is the Blue Ox WDH because it’ll squat if I lower the TT without the Ox bars in place. I don’t have Firestone bags or Sumos, I might get the latter as insurance, they’d mainly act as giant bump stops in my case.

I also have a TRD sway bar you can DIY install (the red bar across the back). I bought it to improve cornering in day-to-day driving, less roll in corners and bumpiness. The added benefit is reduced wind sway when towing.

My Tundra got Ass Implants today

 

It seems the easiest, guaranteed and most cost effective is the air bags. Sumo springs looks promising but not 100% sag proof.

I will put air bags and report back.

 

Works great if thats all that you can do.

Dont know where you live but when you getting under freezing temps expect airlines to start breaking and the little China made compressor to fail. System will start having issues due to freezing moisture (besides them failing because they are cheap lines and fittings) and I don't think that the bags themselves will hold up. Even Semi trucks pop bags when its cold.

We get sub-zero and stay below 32 here in Alaska for at least 5 months straight and so the bags are out of the question. Whole system will bust and fail at the temps that we have up here.

My steel leafs have had no issue with that. As far as sagging, Ive had zero issues with that as well.

 

Agree...that’s what holding me back from adding the air bags.

Went to a place to add a leaf so I can avoid the truck squatting while loaded. Was told it will stiffen the ride while the truck is empty. Unless I try the shop in Dallas that you mentioned in your other post and see if that works.

 

I thought the truck would buck like a Bronco too. I went to the shop in Fort Worth and wanted to order the add-a-leaf and have them put it in. I told them what I needed to do with the truck and my ride concerns.

The owner looked the truck over for about 2 mins and told his guy what to do. Didn't even say
"Trust me", just told him what to do and told me the price. I said ok lets do it and was thinking the whole time if this thing sucks Would turn right around and take if back to them on the drive home when I left.

I was very cautions and put it through some slow speed tests and then got it up on the highway. Did some pretty sharp / simulated high speed "obstacle avoidance" maneuvers and quick stops at high speed and I swear that the truck feels like a Bullet Train on rails and will handle anything I could throw at it as far as the ride goes.

I had a friend ride with me down to Homer just yesterday that owns a 2014 and he was blown away about how nice the truck rode and how well the rear suspension handled everything perfectly.

Ive said it before, no one gets it unless they ride in the truck. Its totally bad ass.

 

I m sold.
I probably will drive to Dallas this winter and have your guy do it. I have asked several contacts here and everyone warned me that it will stiffen the ride quality...
I just read and they are in business since 1928 sure knows their shit very well...

 

Son of the dad who started it still runs the place. Grew up there working with the dad. He's probably in his mid 70's. Every guy that works there had over 20 years there. Only one guy who had 12 years working there. They work on everything, trucks trailers, you name it if its got leafs, springs, and axels.

 

I'm in Central Florida.. How do they hold Up in hell heat? I Ordered them yesterday. They are suppose to have a lifetime limited warranty which probably means if they fail is not covered. Went with the firestone over air lift due to the dual filling valve. Will mount the valve around the hitch and use a ryobi 18 volt compressor that I bring with me every time I tow anyway.

 

You’ll find that the Pro has a softer suspension than the regular Tundra. The firestone bags or a good weight distribution hitch will fix the problem. I use a 550# tongue weight WDH.

 

Have been running Sumo Spring for over a year on my Pro. I was skeptical but thought I would give them a shot for the price . They work as advertised. Slight squat but nothing ugly, I have a bout 2 1/2 inch clearance with coach builder shackles befor engaging. They will slightly compress with a 6k trailer. I did not want the hassle of airbags which tend to fail when you need them most.

 

I installed the air bags today. With ten psi and no load it raised the back about two inches. Drove around the back seems tighter..not as bouncey going over speed bumps. Side to side swing while turning seems better.. Loaded about five hundred pounds on the bed..did not even fudge...Will drop down to five will not towing..Will see tomorrow when I have to hitch up the 6k lbs 30ft trailer
