Heavy trailers or bed loads can make the rear of your truck squat and throw off your steering and braking. These SumoSprings Solo Custom Helper Springs add up to 1,500 lbs of rear suspension support at 50-percent compression to keep your ride level and steady. The microcellular urethane design cushions bumps and controls sway, helping your factory suspension handle extra weight without bottoming out or affecting steering feel.
These helper springs use progressive load control so the ride stays soft when lightly loaded and firms up automatically as weight increases. Lighter loads compress the springs easily for a comfortable ride, while heavier loads can compress them by as much as 80 percent for solid rear-end support. There’s no tubing, air pressure, or valves to fuss with—just a maintenance-free setup that’s always ready to go.

Each spring works independently to support its side of the vehicle. That means when you hit a dip or a sharp turn, the springs help reduce body roll and keep things balanced. Off-center loads are no problem either—each spring adjusts on its own to keep one side from sagging lower than the other.
The closed-cell urethane material resists abrasion, oils, road salts, and UV rays while performing in temperatures from -25 F to 200 F. The springs compress vertically with minimal side expansion, so they fit tight spaces without getting damaged by nearby parts. With simple, no-drill installation and tough construction, these helper springs deliver consistent performance through heavy work, towing, or long drives.

After a year Im still really liking this product. On my tow vehicle 2015 Nissan Frontier I ended up removing the very top section of the spring so that unloaded there was an inch gap between the spring and the frame. Before as stated the ride was stiff but not harsh because the springs made constant contact but werent compressed. That 1 inch airgap allowed for stock ride while unloaded but when a slight load when I stand on the bed for example it would make contact and provide all the benefits. For the Frontier Sumo could shorten it by one pillow and it would be perfect. Still highly suggest these for any mid size Frontier, Tacoma, Colorado, Ford Freaking Ranger or 12 ton truck you are towing with.

I am sorry but I no longer own the Tundra, but I did purchase a Timbren Suspension Enhancement System from Etrailer just over a year for my Tundra replacement.

Thank you for your review. To me, it sounds like you need a weight distribution system. This system will distribute the tongue weight of your trailer. To learn more read below: https:www.etrailer.comfaq-weightdistribution.aspx

After a year or so the sumos are working fine under all of the trailers and loads I have been able to haul or pull

They are working great in my 12 tundra still would recommend them. I tow 8000lbs camper handles great at times I probably wished I got the next step up but might be to hard when not towing. Will see next time I need to get some for next truck. Wish they have measurements to know how high they are from the lighter ones to the heavier ones.
