SSR-610-47 | SumoSprings Rear for Toyota Tundra, Toyota Tacoma, Nissan Frontier, Nissan Titan

If you happen to own a Toyota Tundra, you probably know that they squat like crazy. Oddly enough, they’re rated for up to 11,000 towing capacity (check for your model), but if you have anything more than 200lbs on the hitch you’ve burnt through 70% of your suspension travel. Not any more.My 2008 Tundra rides like a new truck. I consistently tow a cargo trailer that is usually loaded around 6,000lbs, and due to the design, it’s a bit heavy on the tongue. This is why I went with the medium level sumo has to offer. The truck basically feels like a 3/4 ton pickup in the back. That be also means it’s a bit stiff, so be ready for that. If you’re not towing anything super heavy, or very often, maybe look into the light duty version. Visit the website-they have great video resources to help you pick what’s right for your vehicle. I will say they also have great customer service. They answered the phone right away and answered my questions nice and concise. I will likely get some light duty for the springs. Oh and install was a breeze even for someone who’s not super mechanical. Made in the USA.

Soon I'll be doing the 2nd part of a move from Washington state to Maine (see review of Sumo Springs for Xterra under https://www.amazon.com/gp/product/B00ZRWG910), so I've had black Sumo Springs installed on my 2016 Nissan Frontier 4x4 pickup.Was originally looking at airbags, but after my experience with Sumo Springs on the XTerra, it was clear to me that Sumo Springs deliver comparable results at a much lower cost. Even paying the dealership to install them ($70), they were still less than half the cost than airbags without installation. Shocks should also last longer as Sumo Springs will reduce the stress and load on the rest of the suspension system.After installing a fiberglass SnugTop canopy, a Dee Zee heavy weight bed mat (https://www.amazon.com/gp/product/B000VUATBE) , and Tyger hitch (https://www.amazon.com/gp/product/B01MY6IQXX), my truck's rear end lowered by about 1/2". The Sumo Springs brought it right back where it was before.Once the Sumo Springs were installed, I took my truck out for a spin, pushing it a bit, to see how it handles without a load. So far the result is exactly the same as on the XTerra, it handles better, particularly when cornering, and severe bumps are softened in the rear.I'm so sold by these that, once I've completed my move, I will look into the version for coil springs to hopefully give the front end the same kind of improvements.Note: I will update this review after I've completed my cross country journey with a 6'x12' U-Haul trailer, with both the trailer and the pickup fully loaded. But for now, the Sumo Springs definitely get 5 stars...

This is my second time installing Sumo springs. I love how simple and effective they are in keeping my Tundra level pulling 8K pounds and minimizing bounce. I think they are a bit overpriced but you do get a quality piece so I will keep using them.

Tacomas have a very soft stock rear suspension so even a little bit of weight in the bed is noticeable. These Sumosprings drastically improve the handling, ride quality, and squat in the rear with weight in the bed. Currently I have 240 pounds of sandbags in the bed to help with wheel slippage in these Alaskan winters and it makes a huge difference in the way my Tacoma handles. It's also noticeable that it picks up the rear end some even without measuring it before and after because my headlights are clearly pointing more downwards now(which is fine because I'll eventually get a bed cap). Install is super easy, I have no doubts about longevity or durability, and will probably buy these for my next truck whenever that may be.

Actually ended up exchanging for the 610-40 1,000 lb helpers. Don’t need 1,500 lb in a truck designed for 1,000 lbs. (1/2 ton). I lifted the front of 18 Tundra 2” & didn’t want the headlights in the trees with a load or towing. Work great for that & they help with side lean stability. My only issue now is the left (fuel tank side) is touching all the time & right is almost touching which puts them in play all the time & makes for a harsher ride, ( no fault of the sumos). Think I’m going to put 3/4” solid spacer under left spring &1/2” under right for a little space to improve the ride unloaded. Height of the sumos are about 6 1/8-6 3/16” with the mounts. You can also jack the truck up about an inch & just spin them off once you install the mounts if you only want to use them occasionally.

Easy Install…smooth ride!

These Sumo Springs worked great on my 2007 Tacoma 4x4! It helped to stiffen the suspension and it drastically improved towing.

I have a 2016 Toyota Tundra and bought the black springs. I tow a 7800 lbs camper. I must say that it really helped out the ride while towing. If I had to do it over again however,I would probably go with the lighter sumo spring as when not towing the ride is a bit more stiff. I resolved this issue by cutting down the top 3/8 inch of the spring. This did two things. First it allowed my regular springs to work as intended. Second it lowered the front of the camper back into normal parameters so there was no need to adjust the load distribution system. Worked out great
