Most Popular Towing/Load Leveling for 2023 Toyota Sienna

2017 Toyota Sienna van, very helpful for heavy loads and load balancing when pulling 13’ fiberglass and 19’ popup campers. Have used these for years on several different vehicles and have never been disappointed.

Both air bags leaked where the seam is, clearly not heat welded properly, also the air fittings always seep air, so constantly adding air while traveling, I had to order another set from (another site) with one day delivery so as not to miss our trip and then returned the original set from etrailer back to (another site), a fiasco.

I have purchased 3 sets of Coil-Right. The product is very good but the installation instructions were terrible. The first set (2023) I installed per video instructions and it failed. The puck that is placed at the top of the bladder fell of and caused a catastrophic failure. The bladder was punctured and was basically destroyed. The second set (2023) I installed per the video but I enlarged the hole in the puck to help is stay on top of the bladder It failed also. The third set (2024) installed per the new installation instructions which removed the bump stop at the top of the tower. So far they seem to be working better but I think eventually the puck will diappere because there is nothing to hold it inside the spring. Time will tell. This is the only product for my vehicle I can use. 2021 Toyota Sienne LE.

I put these on two Toyota Siennas ('06 and '09). Installation was "easy" without any special tools to speak of. I didn't have to remove the bottom bolt of the shock. If you collapse the rubber and use the red plugs to hold them without air, they will fit between the spring coils with a little coaxing. So far very happy with both. Have had the vehicles loaded heavily multiple times and the difference in load capacity and handling while full is impressive. Ride can be a little stiff if you leave the air pressure at 35lbs without a load. I find around 25lbs is perfect for average use. Anyone with a Sienna knows that loaded down and the trailer hitch will drag in and out of parking lots etc. No longer with these on! Drilled through the bottom of the plastic bumper on one for the valves. The other one I attached an angle bracket to the plate where you would mount a larger trailer power plug. Would absolutely recommend these to anyone with a Sienna. JL in SC.

I did not encounter any issues with the install on my 2011 Sienna awd. However, in order to do the install you need a spring compressor, which I did not feel comfortable with so I ended up taking my van to a 4x4 shop. I like the do nothing/maintenance free aspect of the kit over airbags.

Put this on our Sienna van to help tow our pop-up camper and it worked great. The rear of the vehicle did not go down over the wheel like it did before, and it feels more confident when towing too.

Our 2010 toyota sienna def doesn't sag as much with our full load of 2 parents, 5 teens, and our luggage. No more scraping of our attached hitch on the driveway apron. Since they have progressive resistance, the ride is still comfortable when not under load, but well-supported when loaded. Install was a damn wrestling match - def NOT as easy as the video. Ultimately I'm glad I chose these over the airbags bc now that they're in, they are maintenance free. One note, the version I got did not have holes for zip ties like a preview video had. I'm not concerned about that though bc of the tight fit, there's no way they're falling out.

My pathfinder sagged in the rear There was only 40,000 km on it I bout these Couldn’t get them on, took it to muffler man They had to remove and stretch the spring to get it on They installed it for 500 The rear is about 1,5 inches higher

Great as always, this is my second Firestone Coil-Rite. I had one on my crown vic before and they work great, pretty straight forward install. If you’re lazy like me and didn’t want to remove the shocks then use wd40 to help slip it in between

Exactly what I needed, work great, Thank You etrailer.com!

TOP OF RATING IN ALL MAIN POINTS. QUALITY. SERVICE. EXECUTION OF ORDER.

Great! Keeps our 2001 Sienna from being too squashed. A little rough when there's no trailer though, but I still wouldn't be without them.

I purchased this product for some additional support for our Hummer H2 when we are towing our travel trailer. I removed the springs for easier installation of each bag. I am 66 years old and total time from start to completion was 3 1/2 hours from set up to clean up !

Put these on 07 tahoe. I pull a camper and put 400lbs of tools in back of tahoe. With just the tools I noticed it help put more weight on front wheels. I have not pulled camper yet but with just the minimum 5lbs of pressure it helped with the tools. It took me about 4 hrs to install by myself on the ground. The hardest part was getting it pushed into the coil springs. I ended up using a ratchet strap to help push it in. It was fun trying to get the hose connected afterward, could not see, had to feel and take a picture to make sure it was fully seated.

Having been in the auto/truck repair business for over 50 years, I thought this would be a good Idea so I tried it. I could have made my own but it would be a lot of cutting and drilling because it is so many pieces. I used it to add capacity so I could haul my camper that I purchased three states away and had to pick up. I used 2 of the 3 plates because there wasn’t enough room for three. It did very well like that but after I got back I added the 3rd plate figuring I could use the third one by just jacking the truck slightly before engaging. I thought all three woul be needed once the camper was full of water and gear. I am enclosing a picture of how ti drill the springs with using the vehicles own drill press (screw jack) for changing tires. I still need to test fully loaded and with all three plates in place.

The front brackets did not fit my stock 2005 F3 15 the down rods for the anti-sway bar were too close to the leaves springs to allow clearance for these stable load additions. Customer Service told me that they have never seen this problem before, that is hard to believe with all of the F350s on the road. However, I was told that I could use the rear plates on their own.

Straight-forward installation on a 2007 Pleasure way Excel RV (I did it myself in a few hours) although I did have to modify the air bag mounting bracket with a slot to allow RAS hardware to fit. Great installation instructions. Vehicle height is now correct and could be made level by tension adjustment during install. Handing is improved, I was able to remove aftermarket sway bar which improved ride. I have been considering installation of stiffer rear shocks to soften rebound now that the rear spring rate is increased.

I own a 2020 F150 raptor, it lacks spring rate in the rear to hold up a lot of weight, other than that it’s a beast Pulling trailers. Investigated air ride and I discovered It didn’t have the articulation that I needed. The springs are the fastest way to have additional lift. I can install them and uninstall them in minutes . Great product.

Ok installed outside january 27th. Temp 10 degree windchill -5. I used canola oil since it stays slippery when cold. I recommend taking off the tires. Also wirebrush the coil spring to get rust and debris off. Coat coil spring in canola oil. Also 1997 crv rear will require about 3/4"-1" off of the helper spring before hand. The driver side took 15-20 mins the passenger less than 5. My car rear was sagging it sits level or slightly above level now in the rear. Mileage of vehicle is 73k shocks struts and springs are original. Curt class 3 hitch is also installed on vehicle. I am curious to see how it does while pulling a 5x8 trailer. Overall seems good only time will tell. Wondering how installing two on a side would do?

Working well to help us deal with a heavy trailer.

OEM springs not strong enough. After installed feels a lot stiffer and raised the back 2". Material looks really good. Installation done in 40 min using a nut driver, a flat head screw driver and hand soap. I did have to take wheel off it just makes like easier.

2005 Honda Cr-V, they went on pretty easy, it was a tight fit but no trimming required. I jacked the car up on some stands, had both sides installed and zip tied in 45 minutes..

I installed a set of 1125 Sumo Springs in the rear coils of my Toyota RAV4 Limited Hybrid AWD to increase the spring rate ahead of a cross-country road trip. My RAV4 really sags with a rearward rake when passengers + rear cargo are loaded in the vehicle. This impacts the handling of the vehicle and throws off the aim of my headlights, which leads to other drivers flashing their high beams at me as my headlamps are shining in their eyes. Hopefully these Sumo Springs solve that problem. I’ve driven about 50 miles post install and can tell the ride is much more firm and stiffened up in the rear of the vehicle. The RAV4 feels much more sporty and planted. The install was much more difficult compared to my Sienna. In our van, the Sumo Springs slid right into place - it was a 10 minute job and I didn’t need to remove the wheels. On the RAV4, this was not the case. I had to remove the rear wheels to gain enough space to work the Sumo Springs into position between the coils. The fit was also much more tight; I had to really jam the Sumos into place and slide them into the center of the coil (it was a real arm workout). The Sumo Springs also overlapped about 2”, so I removed and trimmed each down with a razor knife to achieve a ~.5” overlap (per the supplied instructions). Install time was about 90 minutes as I had to remove the Sumos and trim them - which doubled my labor time. Time will tell to see if these work, but I’ve had a set of Sumos in my Sienna for about 15k miles / 1-year and they have done just fine, so I suspect these will too.

Very easy to install (approximately 2hrs.) On a 2002 Ford F150 4x4 Supercrew. I intend on getting a slide in camper so I think they will work perfectly for that application

This product is great! It definitely support the load when towing a trailer. Also, there were several times my truck lost pressure from my hydraulic shocks which the Air lift 1000 saved from bottoming out. Not a solution but definitely save me at the time. I have a 99 Lexus LX 470.

Everything worked as it should. Towing is much more stable especially when you are pulling around 5,000 lbs. I would recommend this to anyone towing with a 100 series Toyota.

These Sumo Springs were easy to install, even for a 70 year old guy. I tow a 7,000lb camper and even tho I have a nice WDH I still had som sag on my Tundra. These helped level it out when towing and got rid of “some” of the bounce. They were really a godsend when I overloaded the bed with about 2,000lbs of pavers. That weight squished the Sumos significantly but the truck drove and rode great. Better and less expensive than air bags.

Pros: Easy install Drastically helps with sag when towing trailers Cons: Things feel more bouncy in the back when not loaded They get hard as a rock in freezing temperatures (i.e. 15*F = no rear suspension) No option to unscrew the spring and replace with bump stop for the winter (at least that I can find, tell me if they make one).

Just installed my new set of air bags (AL60815 Air Lift AirLift 1000 Air Helper Springs for Coil Springs) on my 2008 Odyssey. I purchased this model as a replacement to the previous air bags (F4179 Firestone Coil-Rite Air Helper Springs) that I purchased from etrailer four years ago. I had to replace them because this winter one of the push on fittings broke off one of the air bags. I have been using those air bags for four years towing my 2200 lbs tent trailer. The only complaint I had was that sometimes air would seep out after towing for a few hours. I suspected it was from the push on fittings. That was the reason I choose this model as they have barb fittings and spring clamps. Very positive connections and tight fits. Installation was very easy as all the holes in the tables were already done from the last install. 1. Somethings to keep in mind, if your shocks are a few years old consider changing them at the same time. 2. Remember to support the table with a jack while removing and installing the retaining bolt for the table. Failure to do that will damage the threads on the bolt and rapidly decompress the spring. 3. When drilling the hole in the table don’t rush. Centering the hole so the valve on the air bag does not force against the edge is very important. Luckily there is a template in the instructions booklet. 4. Running the air line to the passenger side bag can be done through the center cross member. I mounted my valve inside the van to keep it clean and out of the way. Using the tee to connect both bags to a single valve will facilitate inflation and ensure they are both at the same pressure. I will be ordering another set of these air bags when I replace this Odyssey with a newer model in a few years. Kit is very complete. All the parts I needed and did not have to run to the auto parts store. Didn't use the heat shield because where I ran the line it is protected from the exhaust pipe.

Great bang for the buck and I had no problems installing myself along with new rear shocks. I had my doubts, but we just completed a 2 week trip fully loaded and towing our popup camper, and they still held 22 psi after all that (started with just under 30 psi so no real leaks!). Definitely improved the ride height and overall handing in all conditions.

It did exactly what we wanted. It helped to cushion the ride and added stability when towing. Very happy with the purchase. It did take a few extra tools to get them to fit properly to my Dodge Ram 2500, but I did get it to fit and it works well.

I had a problem with the Firestone fitment. I own a 2020 ram 2500 Laramie Longhorn. On my truck the distances from the bump stop mount to the strike plate is 6.25”. The mounting hardware for the firestones is right at 2” and the manual states that the minimum height of the bag is 5.5”. So you need 7.5” clearance which means I would have to raise the rear of my truck by 1.25”. I had my truck leveled by 1.5” which makes it perfect and would be wasted by raiding the rear. Other than that they would have been fine. I don’t know if this situation was specific to my truck but if it’s not Firestone should make this clear to ram owners. Etrailer was willing to take a return, minus freight so I only lost $46 to discover the issue. I think the air ride 5000 will be a better fit.

Very impressed with the SumoSprings. Was hesitant at first, but purchased a set for my 2017 Hyundai Santa Fe limited ultimate that had a squishy feeling ride and looked like it sat a bit lower in the back. Installed these on the rear springs and raised the ride height 1" in the rear and the ride is much better already. I'll have to see how they do with a loaded down vehicle but without the SumoSprings, 2 adult rear passengers and 2 dogs in the very back, suspension bottomed out over decent bumps and was not a good experience at all!

Fast delivery and easy to put on. Haven't put the trailer on yet, but rides nice with no weight

I'm not sure if this picture does it justice, but the before pictire with the boat covered, there is noticeable sag in the rear. Dealt woth that for a year. Installed the coil sumosprings helper yesterday and she's level now. Tip, when installing on an older vehicle with rusted springs, take some extra time to sand the springs until the feel smooth. Do that and the dish soap and they go on pretty easy.
