How To Install SumoSprings

My result exactly.

 

After reading this thread daily I ordered the Sumo from Amazon. They came today and it took me 45 minutes that included me rounding up the tools from the barn and garage as well as reading and printing off the instructions given here. I test drove it without the trailer, when I hook it up next time I will take pictures. Thanks for all the info.

So are these the best solution for trying to keep my rear end from sagging with a topper and hitch rack?

 

Opinion: they are a 'good' solution. One of many. I like them.

 

Did you have a chance to hook up the trailer yet? Did you get any lift with these as some people do?

 

interesting question here... i purchased a Hellwig rear swaybar kit for my Pro... we don't have one from the factory. i wonder how well these two will get along. i haven't installed either yet, but i wonder if the Sumos could make the RSB redundant. i want the Sumos for load sag and the RSB for on-road handling, rear body roll specifically.

how much do the Sumos help with rear body roll in an unloaded truck? i'll probably have to play with these two to get the real answer, but if anyone has anything to say about rear roll & handling changes from the Sumos then please speak up.

 

A sway bar will allow the rear axle to travel vertically but limit the difference in travel between the two sides. The Sumosprings will limit the vertical travel for both wheels but will not limit the difference between the two.

 

i know that, i'm asking if anyone has any experience to share. doesn't really matter as i'm installing both at different times and will play around with the combo.

 

Mine seemed to limit body roll in the back a bit. Since they are contacted even when unloaded they do offer some additional stiffness to compression during turns.

 

exactly why I'm asking. the only difference is that it's a Pro, and the rear may sit a tick higher than other stock Tacomas. all good, bar goes in tomorrow and sumos are on the way.

 

The pros should be the same height in the rear as the OR and Sports. At stock height the sumos should reduce some roll. Mine rear has a Deaver AAL and it lifted the rear by about 1.5" and there is a gap between the sumo and the frame of about the same distance. I noticed no difference in handling when I put them on, but thats because they dont contact at all on the road.

 

yeah that's the assumption I've made to justify the bar going in first. it requires a little drilling so i had to make that choice. thanks for the reply.

 

For the price, yes. I've had mine installed for coming up on a year now with no issues. Before installing, the canopy + hitch bike rack + bikes + gear in bed resulted in quite a bit of sagging. After the truck rides nice and level and any harsh bottoming is gone. This is a good solution if you don't want to go the route of new springs, shocks, etc.

 

Anyone got any updates on their overall opinions after having them on for awhile? Thanks

 

Had mine on a few months, no towing but I've loaded the bed with around 300 lbs on 2 or 3 occasions. I notice no difference in the ride quality except for when I hit pot holes or rough road and the rear of the truck can feel like a stage coach, but honestly it felt that way stock too.

Mine are installed with a deaver leaf though, so stock apps may be different.

 

If your rear is lifted, they make spacers. You have to call sumosprings direct, I don't think they advertise these. You need longer hardware. These are 1" thick and I think they have other options. I am running Icon AAL and I wanted to close up the space to contact point to make up for the taller leafs. Of course, I can't say how I like them since I haven't installed them yet!

Hope this information helps someone.

 

Thanks for sharing!

 

Excellent. Yes, most definitely useful information.

 

I have the medium/blue sumo's on my stock TRD OR DCSB 4x4. They've been in for about 3000 miles. I have a bed mat, stock tonneau and AllPro sliders to give an idea of weight in the truck.

The good:
-Truck no longer nose dives. Basically acts like it has a rear sway bar, cornering amazingly better than stock.
-Handles an 800lb 4x4 atv in the bed comfortably and with little squat. Maybe stock height or a little less.
-lifts the back about 5/8 when empty

The bad:
-very harsh ride when bed is empty/not towing. It's worse the slower that you go. Highway is fine. Otherwise feels like a superduty.

I would recommend no spacer on lifted apps. That way you have an inch or 2 of suspension for the small bumps. When you load up, these don't squat much for those who don't like the desert truck look. This way your ride will be enjoyable in both scenarios.

 

Are these better than the firestone airbags? I'm about to purchase the airbags but I came accross this thread. I like these springs because they dont need air to work, seems to be a much simpler setup.
