Rear Suspension Enhancement for 2026 Toyota Tundra that is Sagging When Towing

Question

Question:

Good Morning, I pull a 7200lbs. trailer with a 2026 Tundra and have a bit of squat. I would like the truck level when towing. Will installing Timbrens do this, or should I install airbags. Thanks,

Hey Chuck, I would recommend the SumoSprings helper springs part # SS46PV for your 2026 Toyota Tundra actually. This is similar to the Timbrens but the ride quality is not nearly as harsh but you will get all of the support you'd need to prevent the sag.

Air bags like the # AL84JQ are a solid option too but they require a bit more maintenance since you have to monitor air pressure and there is always risk of them developing a leak. What kind of trailer do you have?

Since the pin weight of your camper is 2.1k, I recommend going with the LoadLifter 5000 opposed to the 7500. While technically there is not reason you couldn't use the 7500 kit, it really is not necessary for a camper like yours. Generally the…
