Sway bars for towing travel trailer????

I just got a 2020 trd pro and debating if I will need to install the rear sway bars. Trailer is 7000 lbs and I have a weight distribution hi

 

How much does the trailer weigh? Looks like you upgraded tires, e rated? Those will help with sway a little

 

The trailer is 7000 pounds 26 feet

 

That trailer has to be close to the upper limit of your Tundra. (My 4.6L SR5 DC TWR is 6800 lbs, similar 5.7L 8300 lbs) If you haven't done it yet, you need to review ALL the truck's tow ratings against the trailer.

Start by checking the TWR (trailer weight rating), loaded truck GVWR (gross vehicle weight rating), GCWR (gross combined weight rating), and truck tongue weight capacity for your truck using the door jamb stickers and Owner Manual to verify that your trailer doesn't exceed Tundra's tow ratings. White and yellow labels are on the driver side door jamb. Payload is a big issue for these trucks. Any option weight you've added subtracts from the payload/tongue weight capacity. (Search. Many good threads.)

If you've already done the homework, then an anti-roll bar couldn't hurt if the truck doesn't already have a rear roll bar. There have been previous threads on the need for which anti-roll bars. (Search)

This anti-roll bar is a little heavier than the Toyota rear bar, and would be my choice for regular heavy towing (shop for best price/vendor):

Edit: @Sgasp90 Actually, Hellwig 7889 for truck with 2"- 4" lift. No lift truck uses Hellwig 7692.

 

The TRD or helwig sway bars do help. Plenty of positive reviews here- folks say it helps a ton with towing and body roll in general driving.

One thing to note- that PRO may squat a good bit. They are "level" vs the 2 inch rake on a standard Tundra, so the squat when towing is more noticeable.

 

I would leave the truck sway bar stock and make sure my weight distribution hitch had sway control built in. You are going to be maxing your truck out if not slightly over with that trailer. I just towed a 6,600 lbs trailer and my GVW was right at 7,200 lbs with the passengers and tongue weight. As others mentioned you will run out of payload before towing capacity

 

Sell and get a 3/4 ton, jk keep it slow! Towing may feel ok until you may need to do an emergency driving maneuver with such a heavy load and youll feel it!

 

Be honest, I didn’t notice whole lot of differences during towing before and after installing the TRD rear sway bar. My trailer is about the same weight/size and I am using weight distribution hitch.
The truck handles the trailer well and, as many fellow members mentioned, payload is THE concern.

 

I’m towing a 32ft Rockwood and no issues. Keep it at 55-60 mph, and you’ll be fine, as the 5th wheelers fly right by you.
