• 🚗【Package Contents】:DuraTPE material with full ring design, reinforces Automotive Coil Spring Buffers/shock absorbers (2pc. Per pack – multiple size options). Designed for sub-compact to mid-size sedans- Up to 4500 Lbs GW, 5500 Lbs when combine with Rubber Block Booster.
  • 🚗【Durable Material & Performance Enhancement 】: DuraTPE Thermoplastic Rubber - Environmental friendly and Resistant to coil abrasion, oil, salt, gravel & UV radiation. Enhances driving stability while extending the life of coil springs and the suspension system.
  • 🚗【Product Dimensions】: 3.1” x 6.8” (T*D); For 1.85” car coil spring gap (when lifted) *Note: coil gap may vary between brands.
  • 🚗【Easy Installation】: When picking the inner groove buffer height “H2” very close to the coil spring “D”, you will get the best support and maximum ground clearance. However, the installation might be a little harder. You can cut off ½” of the top or both top and bottom inner rings to make it easier.
  • 🚗【Peace of Mind】:Enhanced stability: Prevents coil sagging with a reinforced suspension. This absorbs and dissipates the shock from rough road conditions.Most of the vehicle will have different size coil springs on the front and rear coil springs. Please make sure you measure the spring gaps on both ends to pick the correct size buffers.

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.

Coil spring boosters are not new. Superior Automotive has sold them for years through OReilly Auto and other auto stores, Speedwaymotors which caters to circle track racing has also sold them. However, these RubberShox have the variety of sizes to actually most likely fit your car, unlike the limited previously mentioned offerings. Some advice regarding fit: - The diameter of the booster is not as important as the spacing between the coils (corresponds to the H2 on the booster) and the actual coil rod diameter (G2 on the booster). - You MUST pick a booster that has a smaller H2 dimension than the spacing between your extended coil spring. It CANNOT be close or bigger. I originally got the A size for my car thinking that even though the H2 at 1.85" was close to my spring spacing of 1.75" I could force it. Wrong. Brutally wrong. There must be free space to feed the booster onto the coil. Even with the B size I got, which has an H2 of 1.22" getting the booster on still took some serious pushing and finger strength. - Most springs have smaller spacing between the coils towards their ends. Hence, I installed these boosters near the middle of my springs and then rotated them towards the end of the springs. This wedged them into place. Even though zipties were included with my boosters there were no holes in my boosters for them, and I wouldn't nor saw any need to drill holes in my boosters to use the zipties. - Rubbershox says you can use WD40 to mount these. That's controversial as people have said WD40 deteriorates rubber, I used soapy water. The results are fantastic. Concerning raising the rear ride height, that is negligible. Immediately after install there was an increase of 1/2", but it didn't take long for that to settle out right back to the original height. But under dynamic load and motion it is obvious that the rate of my rear springs has noticeably increased. Cornering is spectacularly better. Even at low speeds in parking lots the steering is noticeably tighter. At higher speeds there simply is less body roll, and hence less steering input is needed. I'm content enough that I don't feel the need to get boosters for the front. I have the Pro for the rear (black) and was going to get the standard (red) for the front, but I'm fine with how the thing handles for now. I do recommend for most vehicles that the rear be stiffened before the front. Stiffening only the front will promote understeer. Especially on longer vehicles such as vans and minivans stiffening the rear in comparison to the front will aim towards oversteer and sharpen steering input. There is a lot of torsional twist that occurs in longer bodies and stiffening the rear helps counter that. This is definitely a best bang for buck mod for a car like my van. There is no detrimental harshness. Going over speedbumps is clunkier and louder, but it's a compromise I'm perfectly happy with. My only concern at this point is durability, which remains to be seen.

I installed the Type "A" on my 2005 Honda Odyssey (Front). Big difference in ride. I go over the drive approach, humps with ease. Cornering is easier too because it lessens the "dip". I will be purchasing another set for the rear. I believe I need Type "A" for the rear. This is money well spent, New coilovers are way more expensive. This rubbershox will prolong the life of your suspension. I cleaned my springs with soap and water to make sure there are no sharp or hard debris. Then I sprayed WD40 on both springs and rubbershox. Easy installation.

Ordered size B for the rear of my 93 Acura Legend to keep oversized tires and rims from rubbing. Works great. Be sure and clean the springs well and spray both with WD 40 SILICAN spray and warm the spacers in a bucket of hot water to soften.

Despite having replaced the rear struts, my '96 sable continued to squad regardless of load. I believe the springs were simply too soft. Because of this, the body would also roll forwards and back during braking and acceleration. Tires were just barely tucked up into the wheel wells. With the Type A DuraTPE series installed, all of these issues were mitigated. Now to fix the other dozen things wrong with this old car...

Ok thought I’d try these to see if I could get the old truck to run a little smoother and it dos seem to work, not great but better. So yeah I ordered 2, one set each side. Cheap, so happy it seems to work!

Stiffened up the springs on my 2011 Jetta with 18” rims. Lifted it a little bit. We’ll see how long they last.

I love the clear specifications of sizes. I got the A for the front and A+ for the rear of my 2000 Subaru Forester. After I got the first one in, the other three were easy. I'll probably buy again for the rear of my 2000 Honda Insight.

Perfect for my car, for the front .i got the correct size it worked great! I ordered size CSB (A )

easy to install and lifted the rear on impala, 2 inches.
