A package to help enable the swap of an R230 LSD differential into 1970-1978 Z cars, no core flanges required!

Includes:

• pair of billet 4340 precision CNC machined steel R230 CV/Companion flange adaptors, heat treated, cryogenically treated, and double tempered!
• two pairs (4 each) of precision CNC machined end stops, required to ensure appropriate CV travel
• high grade hardware for mounting brackets, this includes OEM 280ZXT stub axle nuts which are preferred (no peening required) and all other high grade hardware for the install
• optional choice below: custom high strength male male splined axles, engineered with this package

Features:

• made specifically for 1970-1978 Z cars, eliminates the weak and small OEM 4 bolt companion flange bolt pattern, and use of OEM companion flange entirely!
• billet one piece product, uncompromised quality
• ideal thickness to use the very stout *modified R230 CV 6 bolt halfshafts with an R230 differential
• ease of install, you retain easy access to your stub axle nut

Benefits:

• modern technology and performance
• very stout rear upgrade, ease of finding donor latemodel CV shafts with good boots (300ZXTT's and Infiniti Q45's)
• no more U Joints to service or check!
• clears our rear CNC disk brake setup, and upcoming adjustable rear control arms

You'll have to source your own R230 differential along with a total of 4 CV halfshafts, you end up mating the 4 inner flange style 6 bolt CV joints to our custom billet axles including our custom end stops.

These billet pieces only match up with 280Z stub axles which ARE stronger than 240Z units so if you have the chance to upgrade from 240Z stub axles and companion flanges, you can directly swap in our billet 280Z stub axles (or used OEM 280Z units, your option) and our billet CV adaptor/companion flanges.
