U.S. RubberShox DuraTPE Series Front-Rear Car Coil Spring Buffer Cushion/Automotive Suspension Shock Absorber Retainer Performance Booster Kit Universal Type A-F Vehicle Auto Parts (CSB Super, B+)

I was considering these for a while for my '09 Smart 451, and after reading another review about how much they helped I decided to get them. I bought the Red size D for the front springs, and they fit well. Only took about fifteen minutes to install following the instructions. I didn't even need to remove the front wheels. The ride height in the front appears less than an inch higher after install, but feels like a lot more when you sit in the car for the first time. The steering is definitely stiffer, but when after a fifteen minute test drive it was already less noticable. Anyone who has driven a Smart knows how rough the ride is. Even minor bumps in the road feel like you're bottoming out the suspension, and good luck surviving a larger bump or pothole with your spine and all your teeth intact. The ride is immediately smoother after installing this product. I was laughing about how stupid better the car felt over even moderate bumps. I can relax a little while I drive through town not having to constantly scan the pavement for any deviation in elevation to avoid. These are not going to save you from breaking teeth on a massive pothole, but the everyday bumps and divots are significantly smoother.

I own a 2000 Honda ACCORD V6. Four years ago I rebuilt the worn out front suspension and bought 4 new quick struts - 2 front 2 rear - all from here on Amazon. The 2 rear struts are still working perfectly, unfortunately, the two front ones started sagging.I live in a city where the roads are absolutely terrible. It's no wonder that the front struts are already sagging. In the beginning, the ride was very solid - no wondering in the steering or wishy washy handling like a boat on choppy water. But recently I could tell that the ride was starting to get bouncy and the steering less precise.On first inspection of the 2 front struts, there seemed to be nothing wrong with them; no leaks, no broken springs. I guess the springs just started to sag. With these replacement quick struts, I heard it can be a crap shoot on getting the proper ride height and spring rate. But instead of replacing them with another pair that would eventually sag in the same manner in a few years, I decided to try these RUBBER SHOX instead.Just like the other reviews have stated, you have to get the size right. Once you get the size right, the installation is kind of difficult, but not impossible. The first one will give you trouble, but once you learn how to install it, then the other one becomes a breeze. You have to use WD-40 or similar to make the surfaces slippery, and you have to cut down some of the inside lip to get it to fit properly. Also, once you make one complete 360 degree circle, you have to cut off the excess length of rubber. It took me maybe just over an hour to install both. The first one took forever, the second one took 10 minutes.RIDE: These things work! I cannot believe the difference in ride quality. I tested the front suspension out on a very tall speed bump located in a parking lot near where I live. I drove my car right over it and the front end DID NOT bottom out. I few weeks ago I did this and the front end banged hard against the speed bump. That's when I knew it was time to do something about my sagging front end suspension.You don't have to replace your sagging struts. Especially if they are not very old. The springs can start sag but the rest of the strut is probably still OK. Just buy these RUBBER SHOX instead and save ou some hassle.HIGHLY RECOMMENDED!

OK product. was not to bad to install with proper lubricant,was hoping for at least an inch lift thats why I bought the more sturdy ones .I did get about 1/2 lift and tires don't rub as much as before , I can tell I have less side sway also ,little bit stiffer ride but still ok

Installed two sets on 2018 Mitsubishi Outlander SEL with very little lift in the rear. It did firm up the ride. Did nothing for rear sag when hauling my trike trailer. I used the blue but I should have ordered the stiffer compounds.

I bought these buffers for my 2018 Mazda CX-5 front and back coil springs. My wife and I were used to drive German cars and enjoyed the handling during turn. I love the look inside out of my CX-5, but I really cannot appreciate the handling especially on the mountain road. I saw these buffer on Amazon and want to give them a try since they are not expensive at all.The installations are quite simple and easy. However, it did require to lift the car to install. Before buying the buffer, I lifted the car to measure edge-to-edge for both front and back coil spring. The best thing is, their website have detail measurement and installation guide. After lifted the car, I just slide the buffer from bottom of the coil spring (larger edge-to-edge space)all the way to the top. At my first tried, it was hard for me to slide the buffer into the spring. I emailed manufacturer and wondered if I got the wrong size buffers. I got emailed back second day and they suggest sprayed WD-40 on buffers and springs before installation. It only took me 30 minutes to install all 4 buffers to front and back coil springs of my SUV. They should put this suggestion into their installation guide.After driving my CX-5 for next 3 weeks, I am totally satisfied with these tiny cheap buffers. I was so happy for the two mountain trips I had, they made the turn so stable and smooth even with my wife and two teenage kids inside the car and they don't feel dizzy like before. These buffers are also doing very good in absorbing the road bump. I love these buffers!Draw backAlthough these buffers are designed as universal fit, but it is not quite tight fit to different type of the coil spring. The back of my CX-5 is not as tight as the front ones . If you want to buy these buffers, you should make sure the measurement is correct and pick the one as close to your measurement as possible. One little thing, I would like my CX-5 even stiffer. I like the stiffer driving behavior even it will scarify the comfort of absorbing road bump.
