Suspension Enhancement Recommendation for 2025 Toyota Tundra

Question:

Can you please advise which sumo springs to order for my 2025 Tundra, towing a 26’ travel trailer on occasion. My truck is equipped with a 3” TRD lift from the factory. Trailer specs are: Dry Weight UVW: 5,673 lbs. Gross Vehicle Weight Rating GVWR: 7,173 lbs Hitch Weight: ~730 lbs Cargo Carrying Capacity CCC: ~1,500 lbs Thank you for your help!

Hey Greg, thanks for all of the details on your towing setup! I can tell you're very thorough. So while I do have a similar solution that will work for you SumoSprings does not have any kits that will work for your since your truck has the TRD lift. Instead you'd want the Timbren kit part # T45MR which is a similar jounce spring style kit and the adapter part # T33AV which will take up the extra space created by the lift kit. Have you towed with it already and do you have a weight distribution system?

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…

Hello Barry, Since you already have a weight distribution (WD) hitch and are only experiencing a little rear sag, I recommend going with SumoSprings. I typically only suggest Timbrens for those who are towing heavy loads regularly, as they can create…

Hello again Monty; I would get the black SumoSprings Custom Helper Springs #SS66PV. These have a capacity of 1,800 lbs so it gives you a bit over the blue without overdoing it. SumoSprings are a great choice if you don't want to go with the air…
