Atomic Vernier Cam Gear Sprockets – Ford Barra DOHC | Adjustable Timing | Suits VCT & VCT Delete (20mm, Late BF–FG Compatible)
Description:
Get complete control over your cam timing with Atomic Vernier Cam Gear Sprockets, designed to suit all Ford Barra DOHC 6-cylinder engines — including late BF to FG models with 20mm VCT solenoids.
These CNC-machined adjustable cam gears let you fine-tune camshaft position for optimal performance, whether you're chasing a broader powerband, compensating for camshaft changes, or tuning with a standalone ECU. Each gear comes with our custom billet conical washer, engineered to keep the main cam bolt tight — especially important in high-RPM engines with heavier valve springs and big cams.
While these gears are fully compatible with VCT-delete setups, the VCT block-off kit is not included and must be purchased separately if required.
