This adaptor allows you to fit a VT-VY Commodore Master Cylinder onto a HQ-HZ brake booster.
If you have upgraded the brakes on a HQ-HZ, you'll be needing a bigger master cylinder - and the VT 1" bore master cylinder is perfect for the job.
Manufactured from billet 6061 aluminium.
Supplied with 2x fitment bolts and spring washers.
To suit Holden HQ, HJ, HX & HZ models only.
Please note: Will not suit WB models.
