Warning.
- Be sure to check that there is no interference between the vehicle body and the body damper. If there is interference, adjust the installation position using the bracket installation hole positions.
- Make sure that the left and right body dampers are installed so that each side is in the center of the long hole.
- Make sure that there is no interference between the body damper and the vehicle's wiring, etc. If the wiring interferes with the body damper
be sure to secure the wiring to the nearby wiring with cable ties, etc., and allow sufficient distance between the body damper and the wiring to prevent interference.
If the wiring interferes with the body damper, the wiring may rub against the body damper and cause a vehicle fire
