Sumo Springs For Rear Lift?

There actually are separate 2nd and 3rd gen springs. You can get both load levels for each. What you listed are the 500s for the 3rd gen and the 1000 for the second gen. the SSR612-47 is the 1000 for the third gen. SUMO springs for third gen are shorter than the ones for the second gen due to differences in truck design. 2nd gen SUMO will contact frame when unloaded and make ride stiff. 3rd gen leaves about an inch of space when unloaded so unloaded ride is pretty normal. I have the 612-47 on my 2018

 

Put the 610’s on my 2017 when it was brand new, had the leaves with shim and they barely touched the frame, could wiggle them easily.. no lift. After howling tsb completed, springs rest a bit more firmly on the frame, but not too bad. No lift. Maybe differences in opinion are partially due to how much the springs have sagged and which of the 3 leaf packs folks have?

 

Yeah I'm resurrecting an old thread, because I'm pondering Sumo Springs. I've always used bags but maybe something new this time.
According to their web site there is a difference. They just don't specify 1st and 2nd gen. They specify model years. I've noticed reading past threads many have installed 2nd gen springs on 3rd gens and then claimed they didn't ride right. Duh?
So I have a topper (250lbs?), bed mat and tool box(50lbs?) all the time. Frequently I tow a small travel trailer for thousands of miles with assorted additional cargo in the bed. So I was thinking Wheelers AAL 1.5 to restore factory height because of topper, bedmat and tool box. And Sumo Springs for the travel trailer times.
I haven't seen this tryed yet. Inputs? Thanks.

I haven't but would likely go this route over bags next time I do rear leveling with load.

Bags are great, but I like the idea of not having to change air settings, and it just handles the weight when its there. Plus its not as rigid even when loaded.

It's also dirt cheap and easy to install.

 

I have and use daily the Sumo Spring "

$299 SSR-612-47 | SumoSprings Rear for Toyota Tacoma, Black

SSR-612-47". They are the 1000 lb. capacity at 50% compression for my 2017.
They do not rest on the frame when bed is unloaded or unhitched from my trailer.
Daily I drive with my site job box in the bed and it has 50 to 75lbs of weight in it. Springs do not rest on the frame.
Once the trailer is hitched it will ride on the frame and keeps the truck from squatting. Same as air bag's without the possibility of bag failure. I bought these for towing a 6x12 TA enclosed trailer from CO to FL, they worked great and made the drive very comfortable. Thought I would remove the Sumo Springs after my trip. I never did remove them and I don’t feel the need to remove them due to the fact they don't affect daily driving negatively at all. Yes if I hit a speed bump faster then I should, the spring does what its intended to do. An AAL would add height I did not want and a stiffer daily feel I was not looking for. So I have retained factory ride until enough compression occurs to contact spring to the frame. Also daily driving it helps sway stability and roll. I'm happy, but ride feel is subject to you, you'r ass and you'r truck.
Good luck, just sharing my thoughts and experience with them

 

Mine:
2016 TRD Off-Road Access cab.
Snug top canopy.
Sumos installed as soon as I bought the truck Jan. 2016.
All stock, even kept the original tire size.
With no load; cargo OR hitch weight, truck sits with positive rake. With cargo and/or hitch weight truck levels. Ride is good in all configurations.
Used to have airbags on my 02. Tired of maintaining. Very pleased with Sumos and would do it again.

 

I did the

$289 SSR-610-40 | SumoSprings Rear for Toyota Tundra, Toyota Tacoma, Nissan Frontier, Nissan Titan

SSR-610-40 they were a tight fit with the truck lifted up a bit I gained 1" on the passenger side and 1.5" on the driver side. 34.5-36" and 35-36". I have a leer camper top on and bed stiffeners and a bed mat so 200-235# extra. They ride really nice no more lean and no more ass end drop when you stop and go. I have the sport suspension so it's firmer than the OR guys normally. Way better than the stock ones.

 

I installed the sumo springs the first week after I bought my 2019 Sport. The bump stops are useless, but most are. Without a load the truck just sat flush on top of the sumo springs, and with any weight commenced putting a load on them. I filled the back of the truck with bags of mulch and dirt and was very pleased with the progressive feel of the springs and the control of body roll.

I know it's not supposed to be this way, but I feel that after having several loads in the bed the sumo springs seemed to soften up a bit, especially at the top end when they start having load on them. What I mean is that when I originally didn't have any load and the truck barely rested on them, going over speed bumps was pretty jarring. After a few loads it seemed not so much, but hey, it could just be my mind at work.

After driving a 2014 Ram Ecodiesel(written off in 2019 when I was almost killed by a red light runner) with air suspension, this seemed like a more viable option on a truck that I would need to put aftermarket air bags on to achieve the same result. Don't get me wrong, the Ram suspension was a dream when it worked, but I and many other owners started having problems with failures, especially in the winter with condensation in the lines. For what the sumo's cost, it's worth trying them out instead of an aftermarket air suspension, IMO.

 

Maybe I’m bad with keywords but I can’t seem to find how tall these things are out of the box?

 

Sorry to resurrect an old post but I’m just trying to clarify which springs you went with?

 

I'm wondering that myself, don't want them to touch the frame with no load
