PFA Aston Martin 6 Cylinder Camshafts Standard Late 4L Spec
Aston Martin Classic 6-Cylinder Standard Camshaft Set (3.7L & 4.0L)
Restore factory refinement and smooth power delivery to your classic Aston Martin with our brand-new Standard Camshaft Pair. Ground to the definitive late 4.0-litre non-Vantage profile, this matched set includes one inlet and one exhaust camshaft cast from high-grade chilled iron blanks, matching original equipment specifications for maximum longevity and reliability.
Product Overview
Maintaining proper metallurgy is critical for vintage engine longevity. Unlike billet steel units designed primarily for high-wear racing environments where lifespan is secondary, our chilled iron cams feature a natural grain structure that holds oil directly in the lobe face. This ensures superior component life and reduces wear during daily or touring use.
-
Vehicle Compatibility: Ideal as a direct replacement for worn original units across all classic Aston Martin 6-cylinder models (3.7L and 4.0L), and serves as an excellent upgrade/refinement for early 3.7L DB4 twin-carburetor engines running outdated early profiles.
-
Engine Requirement: Complete pair (1x inlet and 1x exhaust camshaft).
-
Quantity: Sold as a pair.
-
Material: Cast on brand-new, high-quality chilled iron blanks (OE specification).

Why Choose Our Chilled Iron Camshaft Pair?
Swapping out tired, scored, or excessively worn original camshafts is essential when performing a top-end refresh. By using chilled cast iron rather than steel, these camshafts protect your finger followers and lifters while offering the refined, factory-correct road manners intended for your DB4, DB5, DB6, or DBS6. Paired with our matching valvetrain components—such as our EN24T Tuftrided valve spring kits, caps, and seats—your engine will achieve optimal geometry and long-term durability.
