Holden Kingswood Brake Booster and Master Upgrade by Lowe Fabrications!

Bring modern braking performance to your classic Holden Kingswood with Lowe Fabrications’ Booster and Master Cylinder Upgrade Kit.

Specifically designed to suit HZ, HX, and WB Kingswood models, this kit uses a VT Commodore-style brake booster and matching master cylinder — modified for a direct bolt-in fit. Each booster is professionally rebuilt to ensure factory-level reliability, and every kit includes a brand-new master cylinder for peace of mind.

This upgrade not only bolts directly into your classic Holden, but also provides compatibility with modern brake systems, giving you the stopping performance expected of a contemporary car. Perfect for street-driven cruisers, resto-mod builds, or LS-converted Kingswoods, this kit combines OEM reliability with Lowe Fab’s attention to detail.

Proudly supplied by Lowe Fabrications — Australian-made upgrades for Australian classics.
