Coil SumoSprings Custom Helper Springs for Coil Spring Suspension - Rear Axle
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
Works well. But I had to go to my mecanical shop to install. Impossible to install by myself.

Timbren Rear Suspension Enhancement System
Bought the TNRARM for my 2008 Nissan Pathfinder V6 4WD. The actual suspension is not even close to the diagram on the instructions. I sent an exploded diagram of my rear suspension to Timbren seeking their advice, and their response was "If your vehicle does not have a bump stop, then this will not be able to be installed." Very disappointed. On a positive note, etrailer was great, product shipped quickly and return was easy.
Nissan Armada. Only about 1/2" longer than original design. Once loaded,still squatted rear suspension like it did before installation. Not worth the high price.

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.

SumoSprings Solo Custom Helper Springs - Rear Axle
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).

Timbren Front Suspension Enhancement System
When I installed these on my 2015 Nissan frontier sv, the bump stops did not sit square with the top plate, but at an angle I wasn't sure how this would effect travel of the timbrens or the function. Not sure if others have same issue or not. Long story short, this positioning caused excessive stress on the mountingnut location and tore at the bottom right next to the mounting bolt. Timbren was contacted and a replacement was sent free of charge. Excellent customer service- friendly, great attitude to help me out. Performance - handles larger bumps/dips better but smaller ones are felt more. Stiffens up front, notice wind gust influence substantially less. Do feel performance has diminished after a year. Upgrading shocks/coils for lift and better ride. May remove timbrens altogether. Someone with a plow would appreciate these more.
Here is my install on my 2WD Ford Explorer front. Easy job, I don't recommend installing these with lowers suspension as the ride is too harsh, I adjust mine back to stock. Works the way I need them to.

Timbren Rear Suspension Enhancement System
They do a very good job of stabilizing the rear axle of the truck when under a heavy load. Towed a 6000 lb travel trailer this week with no load leveling or anti sway bars (helping a friend). The 1500 Silverado equipped with the Timbren system did an excellent job towing the trailer.
I know it will be lovely when loaded or the trailer on. However,it rides like a wagon empty with brand new premium shocks and struts empty. Thud thud thud. You really cannot feel the shocks or suspension. Found exact same item plentiful for 60 bucks on eBay after I bought these for 250. I may cut these in half or put air bag on. I do not like the ride empty. No hard feelings. It is a good product maybe just not for me.

Timbren Rear Suspension Enhancement System
I drive a 2010 Chrysler Town and Country and tow a pop up camper. In addition to that I also carry my wifes 200 lb power chair in the back of the van. Needless to say the back end of my van was bottomed out. That caused the front end of the van to be up in the air thus giving me less control of the front wheel drive vehicle. After installing a new set of shocks and the Timbren rear suspension on my van What a difference it made. I was a little concerned about the price but the results outweighed the price by a longshot. Now with my wifes power chair and the pop up hooked up, my van sets perfectly straight and my vehicle has better control making the trips a lot safer. The best thing is, I did it all myself and saved a ton of money on labor.
Money well spent! Easy to install, the vehicle handles better and doesn't squat nearly as much when loaded or towing. Keeps the rear level and yet ride quality remains the same as prior to install. A tad pricey, but well worth it!

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.

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

got them on in about 30 minutes, just wanted to keep the front end down while pulling the boat. I think this was a great anwser for that. Plus easier on the springs and shocks. Thanks again guys.
I did not notice much/any improvement in ride. I went on to install adjustable shocks, then a Shocker hitch, and finally a ProPride hitch.

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

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.
What our customers are saying:
"WOW! I am impressed! I called to place my order and real person answered, spoke perfect English, albeit a slight southern accent, and my order was sent within a day, shipped quickly and I had it a few days later. I saved over a hundred dollars over local and installed it my self. I cant imagine how that they could do any better. THANKS!"
