Rear Strut Mounting Insulator Adapter Kit, *9/74-78 260Z-280Z

Rear Strut Mounting Insulator Adapter Kit, *9/74-78 260Z-280ZQuantity in Basket:none
Code: 23-4369

  • (2) Strut Mounting Insulator Adapter
  • (6) Adapter to Insulator Mounting Nut
  • (6) Adapter to Insulator Lock Washer

Nissan discontinued Rear Strut Mount Insulators for 9/74-78 260Z & 280Z many years ago. The Front insulators were the same height from 70-78, and are still available, but they are nearly 3/4" shorter than the factory late 260Z & 280Z rear insulator. Advancements in manufacturing technology, combined with an over the top quality engineer looking to expand, has allowed us to bring this complete left and right rear adapter kit to life in a quality that will exceed your expectations. These adapters were engineered from the ground up based on data from a combination of both new and used, front and rear insulators, in order to determine the ideal size for the application.

  • Designed and manufactured in the USA
  • CNC machined from solid 6061 T6 Aluminum Billet
  • Electroless Nickel Plating for corrosion resistance
  • Pre-installed Grade 12.9 mounting bolts
  • JIS nuts and zinc coated lock washers
  • Thick mounting base construction for strength

These adapters, when fitted to the factory front strut mount insulator and installed in the rear of a 9/74-78 Z-Car, will raise the rear by about 18mm (about 0.7") compared to the front insulator alone, effectively replacing the original taller rear insulator (or restoring height for those who installed a shorter option previously). Sold as a pair, one quantity covers both rear sides. Includes 2 adapters and hardware to mount the adapter to the strut insulator. See Related Items below for replacement mount insulators, hardware to replace your original mounting insulator nuts and washers if needed, and more.

Performance Strut Insulators:
There are some performance insulator options available, but those are also designed for the 240Z rear height, and leave late 260Z & 280Z rear ends lowered by about 3/4" more than the front, which is never a good option. These adapters will work with some of them, please call for more information.

Will this harshen my ride quality?
Strut insulators are not entirely made of rubber with studs molded into them. They have a metal core where the strut cartridge bolts on, and a metal shell on top (where the insulator is bolted to the inner fender). The rubber is between the two metal areas, causing the "insulation" between the vibrations & noise of the road, and the body of the car (i.e. you). These adapters simply extend the metal top of the insulator, therefore they will not increase road noise or vibration into the car.

*240Z Note:
Here is another possible use for these adapters: If on your 70-8/74 240Z/260Z, you have chosen to keep using your older stock springs, instead of performance springs, and those stock springs are sagging beyond 3/4 of an inch, these adapters could be used to increase the ride height by approximately 3/4" (18mm) if so desired.

Camber Plate Mount Note:
If you use these to correct the rear height on a late 260Z or 280Z that is utilizing one of our performance camber kits, the original tall nuts that come with the camber kits will need to be replaced with shorter nuts for clearance (not included). Also note that to adjust your camber, you would need to drop the strut away from the inner fender for access.
