Sumo Springs Review

I'm looking at adding a set of these to my '07 Tacoma. When I input my truck into they product finder it pulls the 610 series with all 3 load ratings. What's the difference in the 610 vs 611 and 612? Those #s have nothing to do with the load rating. Can someone elaborate on this?

 

Anyone have experience with these with a Ubolt flip kit on a 17 taco? I want to flip my Ubolts and do this upgrade

 

ordered 610 40s for my 3rd gen last night, i have a camper shell and will be towing my tractor regularly.

 

I ordered and installed the 610-40s on my '07 Tacoma. My frame sits on them with no gap and they raised the rear by exactly 1". The ride isn't bad and tomorrow I'll be pulling my tractor for the first time so I'll be able to evaluate them more after that. I've pulled my boat, and it's heavy, and it didn't squat at all.

 

install went easy, definitely more firm of a ride and bouncy at times but I like my truck to ride like a truck.

 

How do you like them? I think I’ll kill the trigger after getting 2” of squat towing my car

 

Perhaps it's just me, but your trailer looks to be a bit front loaded.

 

I seem to be stuck in the debate of SumoSprings bumperstops or Hellwig EZ-900 helpers. Had my 2020 DCLB loaded up with lumber/tools and noticed the leafs were kinda flat but not touching the bumpstops. Read many articles on this site and still stuck whick way to go. This is a great article because the bumpstops need the space ontop.

 

I got the tundra ones... I take them out when I'm not hauling for camping cus they are stiff as shit unloaded lol

 

Unless you're hauling a shit ton of weight all the time, go with the 500 or 1000 lb model. The 1500 (ihave) tundra model is super stiff unloaded

 

Yeah, looking at the 1000 lb SumoSprings 612-47 for my new Taco. Thanks for the input guys.
(sorry to steal this thread)

 

Thanks guys! This thread made up my mind to get 500lb blue Sumo springs.

 

Possibly an obvious question but I haven't dealt with leaf springs before... When installing these and the u-bolts are loose, is there anything that keeps the axle positioned correctly with respect to the spring? It seems like it would be really easy to get the axle a little mis-aligned. Thanks

 

there is a spring pin keeping it in place.

 

Thread resurrection!

Any insights on how cutting these down impacts load carrying ability? Basically at what point would they be cut such that they could allow the suspension to over-overcompress? No issue cutting them, but don't want to bottom out by cutting them too deep

Recently installed some rear sumos on my '17 - and they are the shorter non-2nd gen springs. However, alongside the Fox 2.5 resy rears, I'm still bumping the heck out of them on normal street driving and the constant "thud" feeling isn't so good on my lower back problems. I do have about 1/4" gap today, but would prefer more like an inch.

 

I cut one wafer off my blue 610-40’s and have ICON RXT leafs in back. It works out well for me, but I have more bump travel/space than stock springs

 

Cool, thanks for the update. I may just end up doing an AAL in the rear or something and leave mine alone. I've just got a set of rebuilt Pro Foxs back there and the rear rides quite plush for the most part, was just trying to get a bit more control driving with some speed on forest roads and reduce the bounce. Need to solve that without feeling a thud in the rear over cracks in the road, manhole covers, etc., But as of now, at stock height, I either need to cut the stop or raise the rear by an inch to essentially restore my factory (OR) rake. Decisions decisions

 

I am trying to make these decisions as well and I'm having a tough time! Hoping someone with some Sumosprings experience can offer some guidance. I have a 2011 DCSB/TRDSport, I did upgrade and put on a Take-off leaf pack from a 2018 OR ( 3-leaf pack) but with my Snugtop topper and camping gear in the rear I get serious sag, and there is nothing worse the the feeling of slamming that bumpstop when I am off-road or getting to a campsite on a FSR. So - I would like to fix the sag and have a good riding truck, but I don't want to put on a big lift or invest a lot of money... The

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

SSR-610-40 seems like a good option, but with the weight I have back there already it seems like the frame will be sitting on the Sumospring. On one hand I will get some small lift and fix my sag, but on the other I will get a "thud" and render my rear suspension/shocks kind of useless since there won't be that 1" gap between frame and Sumospring.... But I really don't want to deal with air bags and hoses/valves... And I don't want to spend 500$+ on new Dakar leaf pack etc...And Toytec told me an AAL would not be a good fit for fixing this sag and they might break... So should I just keep it stock and deal with slamming my bumpstops with full load or should I get the SSR-610-40???

 

Riding with sumo’s hitting the frame constantly is nowhere near as bad as the factory bump stops, but it is still very uncomfortable. You will absolutely be sitting on them and maybe even lifted a bit by them. Your best bet it to pony up the money for airbags or aftermarket springs like the Dakar’s you mentioned or Icon RXTs. I recommend the icons. If you run setup 1 with the shell it shouldn’t lift you much and it’ll ride nice. I ran setup 2 in that config with 1.5 front lift and it kept factory rake and I liked the ride a LOT better than when I was sumos only.

You can’t cheap out on the Tacoma’s rear suspension and still get a nice ride out of it in my experience

 

No experience w/ AALs on my taco unfortunately. I have an aluminum rolling tonneau and a toolbox that is in my bed full-time, but other than that unloaded aside from camping trips a couple weekends per month. This last weekend I had camping gear, propane tanks, full Yeti, kayak, mountain bike, etc., back there driving on rutted out forest roads and the ride was definitely firm, but it did inspire confidence in the amount of control and lack of bottoming out. Back at home, unloaded, the city streets are quite uncomfortable. On the one hand, control is superb with no body roll no matter how fast plus you feel like you can hit nearly anything and not lost control or bottom out. On the other hand, my shocks aren't traveling as much, the rebound on those Sumos is pretty extreme at times. It's never really "harsh" but it's constant pressure given I only have a very small gap (maybe 1/8-1/4") I'm constantly hitting them under normal driving. For me, I'd like to get a mounting plate for them where the mount sits a bit lower if possible. I like them, I just need more space before they engage, or I'll be selling these and going to rubber bumps that leave more of a gap.

Completely different experience on the fronts though. Smooths out a lot and the rebound seems just right IMO. And despite the fact these are both "blue" stops, in my case, the ones in the front do not feel as dense as the rears. I could easily compress the fronts a good bit by hand when installing, not so with the rears....
