It provides a stiffer/stable suspension to absorb and dissipate the shock from potholes and bad roads while reducing stress on the suspension and tires thus enhancing the car’s operational life span.

This product is primarily used to support the Coil Spring and prevent sagging.

A test drive is suggested after installation.

To maximize coil spring support, insert 2 buffers of matching size onto one coil spring (if spring length allows).

There should be around 0.5” ~ 1.5” lift, depend on spring type once it is bearing the car’s weight.

Release the Jack (Stand), and return the tire to the ground.

(This won’t be necessary if the fit is snug.)

For added support, zip ties the buffer to the coil spring.

Once both the spring and buffer are well seated, begin pushing/sliding/twisting the product to the tightest position to maximize the highest buffering support (keep lubricated with WD40 again if needed.).

Continue using WD40 to keep the spacing between the coil spring and the buffer groove well lubricated.

Start from the widest spacing on your coil spring to begin fitting on the buffer, by seating one side product groove INTO coil spring first, then section by section push to fit the sliding into coil spring.

After determining the product size, Completely Spray WD-40 onto both the inside/outside Buffer Grooves and Coil Spring (this lubrication will make the insertion smoother).

If the buffer you choose is too long and overlap on the coil spring, please cut it to align top and bottom (Fig 4). If D very close to H2, you can cut the inside ring of the buffer to make installation easy (Fig 3).
