    I have a 2007 Tacoma TRD DCSB and was looking for information and opinions on Sumo springs? I have done some searching and can't really find a definite answer on whether these would be my answer? I have filled the truck with firewood many times this winter and noticed the sag is ridiculous with the full load. I have the upgraded springs from the recall and they are a sad excuse for a truck spring IMO. Anyone want to give me their opinion would be appreciated.

    I have an 07 AC, and I could swear the TSB springs are weaker than the old ones. I get some crazy bump steer when I have to ride all the way back home with the rear on the bump stops just for a load of oak. And I have a tool box that takes away from the wood space too. These things are a joke. Thanks Toyota. I didn't even think about the sumos till now but that would probably be worth it...

    I installed them on my 16 TRD OR with PRO shocks. The ride quality is really quite good, even hitting bumps and RR tracks. Have yet to tow my boat with the Sumo's but will find out soon. I did hook the boat trailer up, and while hooked the Sumo's are in contact with the frame. While not hooked to boat trailer there's a good 1/2 inch gap between the Sumo and frame. Will update after towing on the road.
    This photo shows much more gap due to the truck being on jack stands.

    Thanks for the replies. I still haven't purchased anything yet for these weak springs. Was also looking at the helwig helper springs. Finally warming up a little here, so installation wouldn't be to bad.

    dont bother with a single AAL ... you are only going to make axle wrap even worse.

    i use sumo springs + HS progressive AAL w/ stupid latest recall leaf pack (5100's). I have a camper and when i load up for road trips, my rear do not sag at all. The frame touches the SS bumpstops but the ride IMO isn't harsh. On a regular basis when it's not too loaded and with just a camper, i have about a quarter of an inch to half an inch of gap between the frame and SS bumpstop. For now it works for me but I'll probably go full leaf pack upgrade when the time comes to upgrade my suspension.

    I went with the ones specific to my year model, 2016 3rd Gen. Part # SSR-612-40. These have 4 rolls, where the SSR-610-40 has 5 rolls. The 40 is the load capacity or density rating. With 40 BLUE being the softest, then 47 BLACK being more firm, then 54 YELLOW being the most firm. I didn't want my truck to feel harsh when the frame makes contact with them, so I went with the 40's. Very pleased with them so far, can't say anything bad about them. Honestly I don't even know they are there until I hook up the boat, then they go to work holding the rear end from sagging so much. Hit this link and read up on them. https://www.supersprings.com/products/sumosprings/

    good to know, I know there was some different models of sumo springs that fit 2nd n 3rd gen. I think they came out with the 612's which are a lil shorter and labeled them for the 3rd gen, but thats probably what id use on my 2nd gen.

    Either ones will work on your truck. It's just depends on what you want them to do for you. The 612-40's I went with have about a 1/2 inch gap between the Sumo and the frame without any load. The 610's would more than likely be in contact with the frame all the time. Can't imagine your 2013 frame being much different from my 2016. Maybe they changed the frames from 2nd Gen to 3rd Gen, I have no idea about that.

    Naw no difference in suspension geometry between 2nd and 3rd, i just think it was when the 3rd gens came out people started to complain about the 610's being in constant contact with the frame and ride being harsh. so they made the 612s an inch shorter.

    If you could do me a favor whats the measurement from the top of the leaf spring pack to the bottom of the bump stop pad on the frame that you have right now?

    And whats the total height of the 612-40 (blue foam + mount)

    I put sumo springs on my 2016 DCSB a few years ago and they have been great! I really don't need them anymore because I replaced my leaf springs with a full set of Dakars. That said, they work great to minimize/eliminate sag. The one drawback is if you do a lot of rock crawling they do limit the amount of up-travel on your rear suspension. If you don't do any rock crawling you should be fine. They are a great solution to your problem, in my opinion.

    Maybe so. Like I said, it's all about what you want them to do for you. But they do work, very good product.
