Factory Differential Mount Bar Insulator, 70-78 240Z-260Z-280Z

Unfortunately, this item has been discontinued by Nissan (along with the Serrated Rubber Washers required for installation). See Related Items for alternative options, such as our Urethane Bushing Kit (23-4139) which fully replaces all components of the original configuration.

Includes:

• (1) Differential Mount (Mustache) Bar Insulator (Bushing)

Description:
This OEM bushing replaces the original rubber and metal sleeve in the differential mount bar. Sold individually, two required per car. Don't forget to replace the serrated washers with these bushings (see Related Items).

Note:
The upper serrated washers that are required to install this bushing have unfortunately been discontinued by Nissan. If your upper washer has worn out, we strongly recommend using our urethane kit instead (see 23-4139 in Related Items), both serrated washers are required to use the factory type of bushing. Factory bushings will not properly insulate the diff mount bar from the body of the car, leading to significant vibration and improper diff alignment. Most used replacements for these washers are already worn out and unusable.

Installation Note:
Proper installation of the factory replacement bushings requires special tools. You will need a saw to cut out the original metal sleeve and a tool to roll the lower lip of the bushing under the mustache bar. Professional installation of these bushings is strongly recommended. If you prefer to replace these bushings yourself, we recommend using our Urethane Mustache Bar Bushing Kit (see 23-4139 in Related Items) since it is much easier to install and requires no special tools. Please give us a call at (714)639-2620& if you have any questions.
