Cautions when you install TTC urethane cushion buffer

- your car should be parked on a flat ground, - select a safe place for installation where other cars do not run around, - your vehicle engine should be turned off for safety, - make sure that your jack works properly before you install the cushion buffer

Checking the condition of the cushion buffer after installing

Check if the coil springs are well interlocked into the grooves of the cushion buffer. Otherwise, it can be an improper installation.

Checking the installing location of the cushion buffer

We recommend that the position of the cushion buffer be in the middle of the coil spring. In general case, the cushion buffer should not be installed on the very top or bottom part of the coil spring.

Checking the size of cushion buffer

If you install a cushion buffer that does not fit to the coil spring, the life span of the cushion buffer may be shortened. Please refer to the standard size table of cushion buffer by types before you purchase and install a cushion buffer. Or contact our customer support center.
