For your 2008 Toyota Tundra, between the SumoSprings Solo Custom Helper Springs # SSR-610-54 and the RoadActive Suspension (RAS) Custom Leaf Spring Enhancement Kit # RAS4611TD, the better overall system is the RAS # RAS4611TD.

The reason for that is the RAS is an active system which continually reinforces your Tundra's original leaf spring suspension. The force normally put on its leaf springs, either when carrying cargo or towing a trailer like you are, gets transferred to the RAS Enhancement Kit, allowing your original leaf springs to work normally, reducing the additional stress put on those springs and ensuring you are level and stable.

The RAS Enhancement Kit also gives your truck better traction and handling because the RAS springs take the brunt of the weight, ensuring your front wheels stay completely on the ground (instead of being slightly raised due to heavy cargo or a trailer's tongue weight). The SumoSprings are certainly a nice upgrade, and when your Tundra squats they'll give it added support, but they don't give the overall benefit to the entire suspension system like the RoadActive does.

That's a good question, and the 3,000 lb RoadActive Suspension Custom Leaf Spring Enhancement Kit - Heavy Duty # RAS34FR is going to be more than your 2008 Tundra needs for your 8,000 lb camper; the HD kit is generally for larger trucks with heavier loads, or if a lighter truck has severe (3 or so inches) of squat. So for your Tundra, I do recommend going with the 2,000 lb RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS4611TD.

Really good questions. And I understand being a bit skeptical of the RoadActive (RAS) suspension system, and it does have its pros and cons for your 2023 GMC Sierra 1500 when compared to the Firestone Ride-Rite Air Helper Springs #F2609. Will the RAS…

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…
