Sumosprings on 1st gen Tundra

Does anybody on here have sumosprings that make continuous contact with the frame? Did it raise the rear up higher when unloaded? I’ve seen a lot of people mention that on the Tacoma forums but I haven’t seen anybody mention that for the Tundras.

 

I bought some, just haven't installed yet.
I'm happy to measure for you before/during install.
I think it will depend on how much sag you already have going on. If your springs are pretty fresh they probably wont make contact much and therefore wont cause any lifts.

I got them because i had airbags and one popped...

 

Lol, I also bought some and haven’t installed yet gotta get new u-bolts.
I too will try to get some before and after measurements.

 

Awesome, I'm looking forward to hear the results from you guys.

 

I just installed mine. much easier than expected.
The yellow sumo springs just barely met the frame, so I did have to jack up the truck a bit to fit them in.
measurements from ground to fender well before and after:
Passenger - 37" went to 37.25
Driver - 36" went to 36.25

So i ended up with approx 1/4 inch lift in the rear. Maybe a tiny bit more than that.

 

I installed my blue sumos last weekend. Did not need to lift the truck drivers side was just touching the frame, passenger side maybe 1/16 off the frame. The blue are the lowest spring rate with 1000 lbs of added support at 50% deflection. I do notice the ride is somewhat firmer but temps have been in the teens. I imagine this affects their stiffness.

 

Just installed black sumosprings on my '03. Felt a little bouncy on the highway yesterday. I had a bit of load with fiberglass topper, camping bed kit and four wheels and tires. When I unloaded the wheels they were still touching with the topper and bed kit. Does help me get back a rake.

 

Hey, I finally installed mine too.

I ended up with blue ones, and I’m glad I did, I would have gone for black but got a good deal on the blue and they seem very adequate for this truck.

My truck is mostly for work, I haul a fair bit of small loads of aggregate, wood, etc, and tow a large dual axle trailer sometimes with various size/weights, and occasionally tow my dad’s boat (an Albin 25, 25’ displacement hull, dual axle trail, I don’t know the overall weight but probably near the limit for this truck).

The Sumosprings made a noticeable difference in regular driving and hauling. I definitely feel the difference unloaded, the rear feels lighter, but not bouncy, I also feel like it reduced my traction, I’ve been spinning the tires more often since installing. The handling seems improved, tightened up cornering.
With weight in the bed and trailer hauling it’s been great, even with a good load of rock, or when towing my dad’s boat the rear barely sagged and the ride was good.

I totally forgot to get measurements of the rear height, but I believe it raised it a little, maybe just enough to make up for sag from age, it’s not dramatic, but as mentioned by hendybop gives a little rake.

I have no comparison to the other densities, but the blue seems just right for my needs and the limits of this truck.
Overall I’m very happy with them and would recommend them.
