Yet another post about SumoSprings

Hi all,

I figure I'd give a review of a few things.

SSR-610-40: This kit was the originally spec'd kit for the 3rd gen tacoma. This was the kit with the blue spring the size of a coffee can. The spring always touches the frame. It is a great kit if you have a lot of weight on the back of your truck. It worked great when I was towing my boat, fully loaded, with 5 people in the truck. Daily commutes were rough though. The ride was harsh and bumps on roads were not fun.

SSR-612-40: This kit came out with smaller springs. The spring is about 1" shorter in length and 2" smaller in diameter. The spring barely touches the frame with a full tank of gas and me in the drivers seat. It was much better than the 610 kit, but still left something to be desired. It felt great when I was towing my boat, but still a little harsh on the daily highway commute. THIS KIT IS MUCH BETTER THAN THE 610 IF YOU DON'T HAVE 500+ LBS IN THE BED AT ALL TIMES.

Firestone W217602407: I've only had it on for a day now but I don't even notice it's there inflated to 5PSI. It feels like the truck did when it was stock which is what I wanted. I'll tow my boat tomorrow and see what pressure feels good and how it drives. Now that I know I like these the best I'll be looking into an onboard compressor and controller. I opted to control the bags individually so I wouldn't run into any issues around corners. I'll probably go with the

$703 Air Lift 72000 Wireless Air Leveling Compressor

AirLift 72000 next time it's on sale.

I did replace my U-Bolts after I replaced the sumosprings with the firestone airbags. You shouldn't use u-bolts more than once when it comes to suspension parts. The threads stretch, so replace them! With a stock leaf-pack you're going to need a 1/2" x 2-1/2" x 6-3/4" set. I found the cheapest ones on Autoandtrucksprings.com. Kit BT5-0074S, $21.75 for a pair with nuts and washers.

If you have any questions feel free to ask!

 

Little confused about your post. So you liked the SumoSprings but took them off for air bags? I just installed the SSR-612-47s due to pulling a boat. Only had them on a day but haven't noticed anything different. Am hoping they will stop the rear of the truck dropping almost 2" when boat trailer is hooked up.

 

I took them off because of my highway commute every day. Big bumps without a load on the back were sometimes harsh and I just got tired of it. They were great for pulling a boat but still harsh over the several bridges I hit on my way to work. They will work great in reducing squat under load.

 

I'm going to add some more fun to the pot about these Springs. Although I know the OP is no longer running these, I feel his post is the most complete in terms of accurate information, all while being very very quick to read!

I ordered a set of SSR-612-40s, and they showed up today. The moment I saw them out the box I knew I had the wrong parts. Keep in mind,

$285 SSR-612-40 | SumoSprings Rear for Toyota Tacoma, blue

SSR-612-40 is in fact the CORRECT PART for our 3rd gens - they should measure about 4" tall without their mounting bracket. Mine are well over 5" in the box, so I can only assume they are 610s in a mislabeled box! SuperSprings has been made aware of the situation and is working on swapping them out for me.

That being said, you may use the taller 610s if you like but you will experience the rough ride quality all of the time since there will be no gaps and the OEM leafs will not be allowed to do what they do. The 612s should give you a bit of gap when the bed/hitch is unloaded making your car drive pretty much the same as if they weren't there in the first place.

Moral of the story - as of this writing SS still is working this out! Measure your new springs!

 

+1 on this. I've got the taller ones for my 2nd gen with Dakar heavies and I have a 1"(or so) gap. I still might cut off another 3/4".

 

I installed these on my 18 Sport about a month after purchase. When installed I only had about an 1/8" inch gap to the springs. I purchased the 612-47's. Is that what your talking about with being no gap between?

 

No, these 610 springs have ZERO gap. they touch the body under normal load. No good for ride quality.

 

Air bags are the way to go. I love them.
Controlling the bags individually is for uneven loads not corners, no ?

 

If you have the bags linked together, around a turn the outside one will compress forcing air into the inside one. I didn't want that so I did separate control. I tow a boat with around 300 lbs tongue weight (when the coolers are full) so I wanted all the stability and support I could get.

 

I didn't know you could link them as one, I have always seen separate controls/ports for both sides.
