Application and fitment
Holden Ecotec V6 Supplier part number: 8531562
Supplied contents
One camshaft for the specified position/profile. Matching camshafts, lifters, springs, retainers and installation hardware are not included unless explicitly stated for this SKU.
Installation and configuration
- Confirm the camshaft part number, engine generation, camshaft drive, trigger arrangement and cylinder-head compatibility before installation.
- Degree the camshaft where required and measure piston-to-valve, valve-to-valve, spring coil-bind and retainer-to-seal clearances on the actual engine.
- Check lifter type, hydraulic preload or mechanical lash, rocker geometry, pushrod length where applicable and the required spring/retainer package.
Recommended associated products
Only purchase components required for the actual engine configuration. Included kit components are not cumulative purchases.
- Required spring upgrade: Crow Cams Holden V6 Ecotec Performance Spring Kit — VTK-ECOTEC — complete matched spring, retainer and lock package. Components inside that kit are already included and must not be added again individually.
- Recommended: Crow Cams Holden V6 Hydraulic Roller Lifters — 3800R-12 — inspect the existing lifters and confirm preload; purchase only if replacement is required for the build.
Supplier recommendations also reference the Ecotec timing set and individual valvetrain components. Those are intentionally not linked until exact BBT product identities are created and verified.
