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

Our 2002 Acura MDX front struts were replaced at 116K with decent Monroe aftermarket parts. The OEM springs were reused. Around 135K, the struts started to feel softer with more lean in turns and excessive diving during braking. It was easy to bottom out the front end over easy bumps. The strut gas shocks are still fine it's just that the springs have aged so there's a lot more front end motion that doesn't inspire confidence in normal handling. At 153K, I replaced the rear shocks since they were original but this did not make a major improvement in overall handling. I considered replacing the front struts and springs with new parts but there's no guarantee that the new springs would provide a stiffer ride. I'm not excited about spending $600 or more to replace struts only to get minor improvement. After a bit of research, I discovered that RubberShox appeared to be a simple solution worth trying to restore a higher spring rate. The MDX coil gap (vehicle lifted) measures 1.90-2.00 inches so I chose the DuraTPE-A size that has an H2 of 1.85. According to RubberShox and other reviews, H2 should match your coil spacing for optimum performance but the spacers can be very difficult to install when these dimensions are close to each other (do NOT choose H2 greater than your coil spacing since it will be virtually impossible to install). As it turns out, I had no trouble installing the A-size and they were a perfect fit. Yes, it took some effort and WD-40 but if you follow the instructions and work by slowly feeding the spacer into the coil, keeping the upper groove fully engaged and leaving the lower groove to be slowly "popped" over the coil as you go, then it works great. I did not trim the spacer in any way but I did use a wooden handle to provide additional leverage to get the lower spacer groove to "pop" over the coil at various points. Once done, this RubberShox spacer is perfect fit as you can see in the photos. I slowly worked the spacers up towards the top of the strut so that they would be somewhat hidden in the strut tower cavity. The overall lift in the front end is about half an inch and looks like the original OEM height now. The improvement in ride and handling is like having a whole new vehicle! You would think that the ride would be stiff but it's not --bumps are smoother and the chassis feels controlled once again. No more excessive leaning in corners and nose dive during braking is minimal. I would say the car handles as good as or better than when new. Such a simple and economical fix! Try this solution if your springs feel soft or worn out, it's a great product.

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 back Although 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.

I have a 2019 Honda CRV EX that has a noticeable roll issue. With so many options, I went out on a limb and tried a pair of the red D size buffers for my rear coil springs. They were easy to install and took about one hour as I lifted one side at a time. Initially, it raised both sides by 1 inch. I drove the SUV after I installed them and the rear was noticeably higher and much stiffer. After driving about 2 miles, it seemed that the coils settled into their grooves and the ride was much better and reduced the roll by about 80%. After my test ride, I confirmed that the coils settled and were back to their original height. My ride was not as stiff as it was in the beginning but now that the rear is stiffer, it seems like the front end and steering feels "invisible compared to the rear. My intention was to reduce the roll and these definitely controlled that. For the price, they reduced my roll without great expense and effort. I may consider installing them on the front springs at a later time. Update: 04/24/2021 I was still having some roll with my CRV after installing the Size D buffers and decided to take another chance and ordered the Red size B buffers. They went in easy because I didn't have to remove the front tires. Once they went in, I moved them to the top of the coils and secured them with the supplied Cable ties. After I dropped the front end, both sides were 2 inches higher at 33 1/2 inches. I took the CRV for a spin to test them and the handling and steering was way better with both the front and rear buffers installed. I can feel the road more but I am so happy with the improvements in the handling and feel of the ride. The height at the fenders returned to their original height of 31 1/2 inches when I measured them after the test drive. I highly recommend these Coil Spring Buffers as a solution to roll on turns. Easy to install, great value for the money and resolved the roll problem.

product well made, easy to install, did not raise the height of the car at all.

Stiffened up suspension nicely. Got about an additional 1/4" of lift with a perfect fit between spring when vehicle on jack. Note used sizes "A" (rear) and "A+" (front). Wish new SUVs with struts were this firm from factory when taking curves. A little bouncier over speed bumps, but not uncomfortably so. Solved towing problem of bottoming out. But don't forget tie wraps. 4 were supplied (2 for each wheel). Used 4 / wheel. Originally, planned on placing two durashocks on each strut. But after test drive with just one, it was clear 2 weren't required. Update 29mar2020: Oh well! Rubber tore in half and dislodged from the spring without even towing anything.

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.

Although there is nothing wrong with them and they are exactly as described IF you have shocks that the coils are thick you would be much better off using something else

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!

I Installed perfect for my kia cerato 2014 and it was improved my steering and lift around half inch, riding smooth bumb even in humps and yellow lane. I highly recommend this product!

Fitted these to the front of our '09 Smart 451 (size 'D' Red in the middle of the springs) as heard that these would help with our terrible UK roads. It has removed the harsh crashing sensation over potholes and makes driving far more comfortable. I would recommend anyone struggling with a harsh ride on their Smart 451 to try these.
