    While I was doing a little bit of research about these, I came across a few posts from other people who were interested in these. Some asked how well they worked, others asked how easy/difficult they are to install. I purchased a set and installed these myself in my driveway. It was pretty straight forward and easy to do. I figured I'd post a quick thread for others to see and be able to search for if needed to possibly help someone else out.

    Maybe others can chime in that have these as well and post their experience with them. This is the first set I've purchased myself and will be using these for our weekend camping trip. If this thread helps you install these yourself then awesome. If you don't like the thread, well then I guess that's just too bad.

    Tools that are needed:
    Sumosprings (I hope you have these before trying to install them)
    Jack to lift rear of truck
    1/2" drive socket wrench
    1/2" drive torque wrench
    19mm deep socket

    Nice to have as well:
    Jack stands (for extra safety)
    Wheel chocks to stop the front end from rolling backwards/forwards once you lift the rear end
    Beverage of choice
    Radio

    Sumosprings are designed to replace your factory bump stops to avoid your rear end from sagging while towing. What these things look like in case anybody isn't familiar with them.


    -First thing you want to do is to crawl under the rear end of the truck and locate the two brackets that your u-bolts are connected too. These will be on the underside of the rear axle, one on passenger side and one on drivers side.


    -Once you find these brackets. Use your 19mm socket and 1/2" drive wrench to loosen the nuts on all of the u-bolts. You don't have to completely remove the nuts, but you can loosen them as closely to the end as possible. Doing this will allow you to remove the old bump stops and install the new springs without actually taking the u-bolts and plates completely off.

    -Now that these are loose, you then can jack up the rear of the truck. You don't want to raise it by the axle or pumpkin. It's better to raise it by a point on the frame such as the bottom of the hitch. Doing this will release the tension of the leaf springs from the axle and create a little more room between the axle and frame. If you lift by the axle it will actually compress the space between the two a little more making it difficult to add the new springs in.

    -Once it is lifted up, place your jack stands if you are using them.

    -Crawl back under the truck and you can push the bottom of the bracket to lift the u-bolts from around the old bump stop. Once the old is removed, simply place the new sumospring where the old bump stop was. Make sure that the u-bolts are actually holding down the spring and not beside the bracket.


    -Tighten the u-bolt nuts in a star like pattern snugly at first. Once they are snug, finish them off with your torque wrench to the proper torque setting.

    -Repeat the same process for the other side.

    Comparing what the factory looks like to sumosprings.


    -Once both sides have been replaced, remove jack stands and lower the truck.

    -Drink your beverage of choice and admire your handy work.



    Disclaimer: I'm not responsible for anything that you may do to your truck. Perform this at your own will and accept anything you do as your own fault. These may give you a slightly stiffer ride, but if you tow regularly then these may help you out. Plenty of people use these on their daily rides. I used helper springs on my last Tacoma and decided to try these out on this one.

    No problem. I've used my share of walkthroughs from up here that others wrote out. Figured I would try and take a few minutes to return the favor. I tow an a-frame popup that weights around 3k after my gear is loaded. It is tongue heavy so these should help. I'll be trying it out this weekend.

    I just got my Sumo Springs in the mail today. I will be installing next week. Thanks for a great and simple write up with pictures. Your write up differs slightly from the included installation instructions, but yours is looks easier and faster.

    Thanks for the great write up! I'm considering these as a drop in replacement for my factory bumpstops. I sometimes carry loads which causes sagging. I have dakars which gave me 2 1/2 inches of lift in the rear. Does that mean that the sumosprings will not add to my lift? Also does anyone know the compressed height of the sumos? I need a taller bumpstop because of my lift and was thinking these might solve both issues I have.

    I believe they make sumo springs with a taller spring for other trucks. My spring measures 5 inches tall. Contact manufacture and ask what model is taller and by how much. You will solve your question.

    Sumo springs only manufactures 2 models specifically for the tacoma, SSR-610-40,
    SSR-610-47,
    The. 2nd being for heavier loads, same physical dimensions.
    any other option would be using one of their products that is designated for a different vehicle. Not something I'm against, another member on here had luck using GM bumpstops mounted to the frame above the leafsprings and it would contact his u bolt flip kit on compression.

    Yep with factory springs I gained a little over half an inch in the rear like another user posted. With aftermarket springs, you may have to do some research and see what other springs are out there. These said they were made for the factory leafs packs but the installation wil be the same.

    When I was reading the included instructions it did differ just a tad. It seemed like they had pictures of the Tacoma but the instructions seemed pretty generic. They also included a tube of loc tite to be used on the u-bolts. I didn't use this as I will be replacing my suspension eventually and didn't want to deal with struggling to remove the u-bolts.

    The loctite is not for the u bolts. It is for the threads that mount the sumo spring to the base.
    The sumo spring is threaded on the base and by using the loctite it can't vibrate loose from the base bracket.

    Go with 1000 or 1500lb rating? How does it affect the ride and loads in the bed and towing? Where did you buy and how much?

    I put them on my 2007 and swear by them. They'll be on my yet-to-be-bought 2017. $200 or so on Amazon.

    It's an easy install. Youtube it.
