Distributor Vacuum Advance Unit Holden VC VH VK VL / Ford XD XE - VA1000

Engineered for Ford XD, XE Falcon in addition to Holden VC, VH, VK and VL Commodore models, the Distributor Vacuum Advance Unit plays a vital role in managing ignition timing under varying engine loads. This component helps deliver smoother acceleration, improved throttle response and more efficient cruising performance. By responding to engine vacuum signals, the unit automatically adjusts ignition timing to suit driving conditions, helping maintain optimal combustion and drivability.

Key Features

• Vacuum-Controlled Ignition Timing Adjustment: Uses engine vacuum to advance ignition timing during light throttle and cruising conditions.
• Improved Driveability: Helps provide smoother acceleration, better throttle response and more efficient part-throttle performance
• Internal Diaphragm Operation: A sealed diaphragm reacts to intake manifold vacuum, advancing the distributor timing as engine load changes.
• Durable Construction: Manufactured from galvanised metal for strength and longevity, and the Zinc-Plated finish provides added corrosion resistance, helping withstand engine bay conditions.

Model Suitability:

• Holden VC Commodore – 6 cylinder
• Holden VH VK Commodore – 6 cylinder & V8
• Holden VL Commodore – V8
• Ford XD XED Falcon – 6 cylinder & V8
