Sumo Springs for lifted applications

I updated the first post after riding around with the Sumo springs with 1.5" spacers inserted.

 

nice update. i was thinking of doing the same set up with the spacer but i found it unnecessary ATM with the SS Bumpstop + HS 3leaf AAL. I kept the overload on mine though. With the camper on, i can barely fit my finger between the frame and top of SS bumpstop. I have loaded up the back but haven't found the ride too bumpy ATM. Maybe this is due to the fact i have new 5100's in the rear as well.

 

Do you have the updated TSB Toyota Leafs? I was unable to keep the overloads as it interferes with the progressive AAL brackets.

 

yes i did get the latest tsb pack and at times i wish i didn't get it..lol anyways i had no issues with the headstrong AAL and this latest TSB leaf pack.

 

Thanks for all the trial/error OP. I have a 3rd gen with a set of SumoSprings in the rear paired with a set of Bilstein 5160's. Have had this setup for over 6 months now. And the frame does rest on the SumoSprings with the stock leaf pack, and provides relatively 5/8" of lift in the rear.

Lately I've been thinking about getting/adding a set of the Headstrong Progressive AAL to the mix, to try and accomplish two things:
1) Add a bit more rake, as I have a set of Bilstein 6112's in the front (3rd setting)... So the truck sits more or less level now.
2) soften up the ride a bit in the rear. The 6112 are great on the front, but since the frame is resting on the SumoSprings in the rear all the time, it can be a tad rough.

Adding a progressive 3 leaf pack seems like it would accomplish this. However I'm a little worried about removing the overload and I don't want to decrease my weight capacity, but at the same time I'm worried if I keep the overload, the ride would be just as rough as with the SumoSprings ridding in contact with the frame....
But this tread kind of had me thinking, if I do remove the overload and get a 1.5" lift in the rear, and there is a gap between the SumoSprings and frame (like the last couple pics in the OP), will the SumoSprings act like a overload more or less when adding weight and/or towing a trailer? That is to say, when weight is added, will the SumoSprings compensate (as much as they can) for not having a overload leaf? Would it be better to keep the overload in?

I know I have a 3rd gen, but the rear end leafs aren't to different I don't think... Not like we're comparing apples to oranges, more like red apples to green apples.

Worth noting that I don't have a topper or carry much weight. But during hunting season I do tow my Ranger often, load down the bed with corn, etc. So like I said I'm not real keen on scarfing carrying capicity.

Sorry for the long post.

 

Honestly I would keep the overload in. The sumo springs would help your rear not to squat too much when you load up during hunting season. I remember loading up my rear bed before and hitting the OEM bump stops pretty good when I would hit a bump, did not feel good at all..lol

 

You have a Headstrong Progressive Leaf set, with overload in, you still have space between the SumoSprings and the frame you said, right? Just not a lot. But you have a topper causing some squat... Wonder how much more of a gap you'd have with out the topper and additional weight?? Huummm.

Thanks for the input

 

Removing the overloads and replacing with the multi-leafs will give your ride a softer feel. However with the Sumo Springs, You should have about a 1/2" gap between the frame the Sumo which should provide a less rougher ride. The Sumo has 1000 lbs additional carrying capacity which would compensate for the overload's being taken out. I have not towed with the Sumo's at my current set up yet but I suppose it would make your frame sit at the Sumo's when loaded. The issues with the Sumo's is that on stock rear, it's always sitting on the frame acting like bump stops so the ride is harsh.

If I had to do it again and tow a few times a year, I'd go airbags. If no towing, full leaf pack. Even with a full leaf pack, airbags can be added if you decide to tow. It will just cost you more money up front. I'm really never done with my set up so it's always evolving.

Now with the TSB leaf and Wheelers multi-leaf AAL, the brackets line up on both so I decided to leave the overload's off. I hardly tow or load the bed so I decided to try the Sumos. Per above, there shouldn't be an issue with Headstrong multi-leafs.

With overload's in, they provide an extra 1/2" of lift.

 

Thanks for all the info.

 

So I've been researching the Sumo Springs for a bit now. I have a 16 DCSB 2.5" levle up front and a 1" block in the back. Measuring between the leafs and the upper frame bracket I have about 5 5/8" of space. Sounds like I'll be touching the Sumos full time unloaded, but staying at the same leveled point with a moderate load in the back.
I have to drive from Savannah, GA to West TX and the back of my truck will be full. I want to keep from squating too bad in the back and putting that load on the stock leafs for that long.

 

So after some miles with the Sumo's just barely touching the frame, I can say that I prefer the ride much better. On an empty bed, I can still tell that the Sumo's was back there but was not as stiff. I recently hauled about 500 lbs of stuff in the bed and rear squatted less than an inch and the ride was good on the highway. I also hit some trails and the Sumo's would compress to about 3" (height of OEM bumpstop) during flex. Can't tell that they were back there off-road.

 

I've noticed much better control of body roll.

Thats good to hear. I was worried it's gonna be too jumpy. I'll go ahead and order them up.

 

Did you get ot to work with both spacers??

How can I ordrer them? I have the new recall leaf pack with a 2.5" aal

The distance between my frame and leaf pack is 7"

I think i need these spacers.

Any help will be great!

 

I don't remember who I was working with but I just went to their website and used their "contact us" and someone replied to me within a day. They did say that they were looking to make the spacers available as an option.
