Please refer to the size choosing manual in the listing. Please jack up car first and measure the gap to determine the size. If you can send over your measure distance, we can help you determine size. Also, there are four different types hardness for CSB, CSBPlus, CSBPro, and CSBSuper series. CSBSuper: 6000Lbs GW and 7000Lbs combined with Rubber Block Booster CSBPro: 5500Lbs GW and 6500Lbs combined with Rubber Block Booster CSBSPlus: 5000Lbs GW and 6000Lbs combined with Rubber Block Booster CSBS: 4500Lbs GW and 5500Lbs combined with Rubber Block Booster RubberShox Team **Q: Anyone know the size for the rear or a Ford Maverick?** A: If someone has the same make, model, year and trim as you, they might be able to tell what they used. Word of caution because they may be ordering them for a different purpose. The different colors reflect capacity and/or stiffness and each color has different coil buffer sizes. With that being said, you will have to jack up your vehicle and write down measurements and dimensions for your coil springs. Use this information to select the buffer that best matches your springs. Note that the front and rear springs on my vehicle were different so I had to do this for both front and rear springs. This proved to be a great "drill" for me to prepare me for the actual installation of the buffers. H1 is the vertical space between the coils when they are unloaded with the vehicle jacked up. Coil spring spacing also varies on the position on the springs and may fit better and respond differently on a different position on the coils. I installed mine closer to the top of the front springs as they seemed softer than stiffer in the middle of the coils. H2 is the loaded coil spacing with the vehicle on the ground. If you select an H2 dimension that is greater than your coils H2 height, the buffers may lift the suspension. If it is equal or less than your coil's H2 dimension, it won't affect the height or change wheel alignment. I went with an H2 height that was less than the spring height so that it wouldn't affect the suspension. I rotated the buffer into the area where it fit best and verified the height of body at each wheel well remained unchanged from before the installation. Use D1 and D2 to identify the buffer size to match closest to your spring diameter size. The buffer is somewhat flexible and will stay put on your coils once the springs are loaded and secured in place with the provided zip ties. D3 is the diameter of the coils that will fit within the buffer groove and will also hold the buffer in place. There are some hacks on-line to help with getting the buffers installed. I selected appropriate sizes for the front and rear and used WD-40 to lubricate the buffers and springs making installation much easier. Unless your vehicle is new, the process will be messy so have hand towels or rags handy to clean up the mess. Save the measurements and sizes for future use to double check the buffers before installing them. Hope this helps. I was very happy with how the buffers reduced the amount of roll and sway without throwing off the suspension and alignment. I later removed the rear buffers because using only the front buffers worked perfectly. If I have to haul heavier loads, I could put the rear buffers back for more stability for the extra weight. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple fix for soft Acura MDX struts *by L***I on May 29, 2021* 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. ### ⭐⭐⭐⭐⭐ Smart Car owners! Buy this right now. *by A***. on March 12, 2025* 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. ### ⭐⭐⭐⭐ OK product for minimal lift *by R***N on May 10, 2025* 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 ## Frequently Bought Together - 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, F) - B-12 0116 Chemtool Fuel Injector Cleaner, 15 Ounce, (Single Unit) - 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, A-) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/162256632-u-s-rubbershox-csb-series-front-rear-car-coil-spring](https://www.desertcart.kg/products/162256632-u-s-rubbershox-csb-series-front-rear-car-coil-spring) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-10*
