Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Rear Axle
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.

Timbren Suspension Enhancement System - Rear Axle
Great product and performed as I had hoped. My 2011 Xterra Pro-4X has weak leaf springs and bottomed out on bigger bumps. I didn't have the capital to put forward on new leaf springs so I added the Timbrens. I gave these 4 stars as Timbren shipped me the incorrect spacers twice (at no cost to me). Their customer service was great, and found an error in their process. After getting the height and spacers correct with a small gap, they do their job very well and I am happy with the performance even after a year. I would definitely consider purchasing again.
I bought these for my Xterra to help eliminate sag when towing. I don't tow a lot and I liked the idea that these units wouldn't affect the ride the rest of the time. First impressions of the quality. The thickness of the steel brackets is great almost look heavier than they need to be. The rubber springs are very solid and seem like they will last a long time. The included hardware seemed to be of good quality as well. My only complaint was the finish on the brackets. At this price point I was hoping they would be powder coated but they are painted. Not a huge deal but right out of the box some of the paint was flaking off like the parts weren't prepped properly. I ended up scuffing them down and spraying two coats of bedliner on them. I am hoping that will help keep them rust free. Installation was very easy and I had no problems getting them pretty centered over the axle. I did have the opportunity to tow since the install and they really did make a huge difference. I gained about 2 inches of height when fully loaded. The ride of the vehicle was very good and the handling was very stable. I drive this vehicle every day and when not towing it is a little stiffer at times, but certainly not enough to be a problem. I am at 60k now and plan on replacing my shocks shortly so I am hoping that will help. Overall, it was a worthwhile upgrade and I would do them again in a minute.

Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Rear Axle
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.
Pretty easy to install. During my first drive with them installed I heard a lot of thumping even over small bumps, but it seemed to work itself out on the second drive. I think it helps level out the slight sag in the rear of the car, and the front wheel drive which used to slip frequently when towing gets better traction. Be aware that for a 2005 Highlander, there are no holes or zip ties, and you can't get the Helpers to stay much higher than the lowest coil. I think them sliding down is what eliminated the thumping.

SumoSprings Solo Custom Helper Springs - Rear Axle
I waited until I could drive the MH to rate this purchase. They were super easy to install. This difference was subtle but noticeable. Less body roll in corners and in windy conditions. This also resulted in better steering and a more relaxed drive. Well worth it!
Good quality, clear instructions and fast shipping

Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Rear Axle
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

RoadActive Suspension Custom Leaf Spring Enhancement Kit
I received this kit in a very timely manner always do from etrailer have some issues with the instructions that come from roadmaster not a trailer the bump stop spacer didn’t say that you need to use the original bolt from the bump stop so it slowed me down greatly on the install however I took it out on a quick run without a load I do feel that this has made the unloaded ride smoother tomorrow I’ll be taking the trailer out for a bit and we’ll see how it works there and I’ll update this rating.
Works great with our fifth wheel

Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Front or Rear Axle
Pretty easy install on a Winnebago Solis, built on the Ram Promaster 3500 chassis, took about an hour to install on all 4 wheels. I only parked on a level surface and used the factory jack, didn’t even lift the van off the ground all the way but enough for clearance to install, no tire removal done. I gained about an inch of clearance which is nice for my onboard generator and hoping for a better ride on windy days. The pictures are before and after of (in order) front, rear, size difference of Sumo vs. oem and the generator.
I added Sumo Springs to my 2019 Winnebago Travato on the Promaster chassis, and it made a huge difference in handling. Better ride, less sway, and surprisingly, not any harsher. Would definitely recommend.

RoadActive Suspension Custom Leaf Spring Enhancement Kit
You van feel the difference right away. Gave my truck a little more height without a load. Truck feels more stable a turn/curve. I still have to put a load on it to check the differences. But, I imagine I won't have any problems based on everyone's else's reviews.
The springs work amazingly, I made the installation a little harder by not reading the instructions completely. But after a phone call and a little guidance I had them on in no time. Thanks to Ashley and Jill for their help and patience.
