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. ## 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.tw/products/162256632-rubbershox-csb-size-f-coil-spring-buffer-spacer](https://www.desertcart.tw/products/162256632-rubbershox-csb-size-f-coil-spring-buffer-spacer) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-09*
