SuperSprings CSS-1168 | Coil SumoSprings for various applications | 1.68 inch inner wall height, Black

This product is rad! I was looking for a product that would 1) help reduce sag a little bit while loaded down (for me that is when I am towing), 2) that wouldn't affect my on road driving adversely 3) wouldn't inhibit my ability to drive off-road, over obstacles, etc. both while not towing, AND while towing and an added bonus was easy install and little to no maintenance. This seemingly silly SuperSpring Coil SumpSpring insert TOTALLY did the trick! I've got about 5000 miles on this set that I put in the rear on my 2018 Jeep JL Wrangler Unlimited Rubicon. First thing I noticed right after installing was the Jeep was MUCH more stable. Some call it "stiffer", that's not how I would describe it... It wasn't any more harsh or stiff, it just seemed to help manage roll and the rebound seemed more healthy. It actually absorbed bumps better in the rear and made the front end actually feel more in control.Additionally, this helped handling while under a load (towing) my Hive EX offroad expedition camper trailer BEAUTIFULLY... it was literally like there wasn't a trailer back there. Immensely improved handling. I saw close to an inch less sag in the rear too, which was great! Went from almost 2 inches of sad, to just 1 inch when towing. I was skeptical on how it would do with sag, though i was more concerned with improved handling characteristics, but this little sumospring improved on both.Lastly, I really wanted something that I didn't have to remove or worry about popping when articulating and getting flexy and more technical offroad. I hit some pretty good trails and went fill flex, and actually saw that my stock rubicon suspension on 35" tires no longer rubbed the inner fender liner in the rear at all when fully articulated. After the trail abuse the sumospring still seems to be in good order, in position, and functioning just as it did before offroad outings.I am VERY pleased with this product for the money. It is truly an upgrade whether you adding weight or not, and it really did impress me. I like to think i am a harsh critic, and for the money of this molded piece of foam material, I was extra skeptical, but I was VERY impressed and fell in love with this product quickly. I HIGHLY recommend this for those looking for something that will improve suspension feel, handle the beating off 4x4ing, and aid with heavy loads/towing. It has been monumental for us.

Easy install on a 2017 Ford Expedition EL XLT 4wd. Jacked up the rear end, removed the tires, cleaned the coils and lubricated them (and the sumosprings grooves) with dish soap (no water added). Seat the bottom groove first and then used a flat head blunt screw driver to push the front top portion in. Once that was in the rest was cake, just slide the rubber forward around the coil. I agree with other reviews it is cheap they include only 10 zip ties when. There are a lot more holes to secure with ties. Will update after towing next weekend.

2013 5.4l Ford Expedition XLTInstall was a breeze, I can only assume one of a few things for all those struggling and those are:1. People are not jacking the car up.2. People are not taking off their wheels.3. People are not measuring the coil spring for the largest coil opening (they are not the same on each wrap)Install took me about 30 min for both sides, granted I have a scissor lift in my garage so I'd say its a 1hr-1.5hr job for someone that has to use a jack and jackstands and/or doesn't have air tools to do the lug nuts.I just took some dial hand soap (no water) and rubbed it lightly on the coil wrap I was using as my mounting wrap and inside both top and bottom of the sumo spring. Popped it around the coil and started sliding it on in the middle coil (largest opening) pushing it around as I popped it in place. You need to put the bottom of the spring around first, and then push in the top based on the grooves.It's almost an insult the amount of zip ties they send, it comes with 10 in a package, and you need at least 24 to put one in each hole. Either send enough or none at all, just obnoxious to have less than half. Thankfully I had read the prior reviews with complaints about this and had some ready.My truck - My truck has 130k miles with about 35k of them towing a 28' Aspen Trail travel trailer with roughly 800-1k tongue weight(depending on load) on a load distribution hitch with 1200lb springs. The expedition, contrary to people saying it's the hitch setup, runs real low rear spring weight springs and they sag like crap even with my 20' boat with about 300lb tongue weight, even my whitewater raft trailer that I can pick up by hand sags the truck about 1/2".Unloaded road test - Notable improvement in rear end stiffness. This could be from picking up slack of worn out springs, or just simply the increased spring rate. Ive had this truck since 30k miles, and I don't remember it ever being quite this firm. It's not the same improvement you'd see from hellwig sway bars, but its definately there and noticeable.Loaded road test - Coming this weekend as we're going camping. Will update.

I liked the ease of installation, using some good old-fashioned dish soap they slid right in place. Help with beefing up my front suspension on my 2017 Silverado to support the extra weight from my new snow plow.

Worked well in a our 2011 Kia Sorento to support towing a 2200 lb tent trailer. Tongue weight added to hitch was around 250 to 300 lbs. plus additional payload (food, luggage, etc.), plus 2 adults and 2 children....our SUV was sagging and front end was too light compromising the steering.Company website doesn't have info for Sorento but I know from experience Hyundai Santa Fe and Sorento share the same suspension components so I ordered the one specified for the Santa Fe.The springs installed easily and was done both sides in about 45 mins.These super springs tightened up the handling while towing and reduced the amount of sag. Could our SUV benefit from more support (ie. stiffer or taller inserts)? Yes it can. I'd say these offered mild to medium support. Even though these springs are not vehicle specific, it adds decent amount of support to our vehicle to restore confidence in handling. Regardless what type of suspension support you use, it does not fix careless weight distribution or towing above max capacity or exceeding tongue weight, etc. All in all I'm impressed.

Installed this on my 2008 Santa Fe. These were very easy to install and took about an hour total. Added 1.5" of height and the car looks much better. Handles great too.

I needed something to help with the sagging on my 2007 Honda Odyssey when toeing our tent trailer. The install is straight forward, after removing the wheels and jacking up the vehicle. I added a few more zip ties as the kit doesn’t come with enough in my mind.Ride is firmer when empty and less sag when towing. Height increased about .75” but seems to have settled

I have a plow on the truck and it gave me the clearance I needed

Installed easily in my 2008 Honda Ridgeline. Makes a huge difference when carrying the ATV in the bed. Highly recommended.
