## Description

RubberShox DuraTPE & DuraTPE Pro Series- Front-Rear automotive coil spring buffer/booster kit is a shock absorbent accessory package that provides a tighter, more resilient suspension.- This absorbs and dissipates the shock from rough road conditions with greater driving stability while extending the life of coil springs and the suspension system.- Universal Fitment Type: A / A+ / B / B+ / C / D / E / FPackage List:2 * Premium Shock Absorber Spring BuffersNote:Please allow 1-3 cm error allowance due to manual measurement. We appreciate your kind understanding. What is the difference between DuraTPE CSB series and the DuraTPE Pro CSBPro series?DuraTPE Pro uses high-density TPE material that removes the body hole to increase compression and flexibility. The hardness rating 65 is higher than the standard DuraTPE series rated hardness at 60. DuraTPE Pro, due to stronger material, it roughly raises ground clearance 1”-1.25” per buffer set installed) compared to the DuraTPE raises ground clearance roughly 0.5” ~0.75”.How does this product make my car feel "stiffer" while driving after they are installed?DuraTPE / DuraTPE Pro series with industry-standard hardness 60, is designed to add firmer and stiffer support to the older shock suspension. It also increases the ground clearance for the vehicle to preventing low ground clearance vehicles from hitting road bumps.When do I choose DuraTPE Pro over DuraTPE ?Choose DuraTPE Pro series if you are installing onto a heavier SUV or truck and prefer a higher ground clearance and a stiffer ride. Choose DuraTPE for your sedan if you prefer a softer ride and less ground clearance.

A: Hello, 
thank you for your interest and inquiry,  the buffers will aid and provide resistance your your coild to provide a stiff suspension feel.  you may experience a small lift between 0.8 up an inch by not letting the coil from fully compressing. 

super is the denses and gets softer going down to plus, pro and standard series.

**Q: Cuales son los que puedo poner en una toyota rav4 2018 delantero y traseros**

**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.
