Unlock the full potential of your S54’s valvetrain with our High Performance Cam Followers/Rocker Arms, built for precision, durability, and reliability in high-revving performance engines.
Crafted from forged chromoly steel and finished with a diamond-like carbon coating, these cam followers are engineered to deliver exceptional strength, reduced friction, and outstanding wear resistance, ideal for demanding street or track use. Each unit is precision-ground for consistent clearances and smooth, stable valvetrain motion at all RPMs. Despite heavy-duty construction, our design retains the same weight as the factory rocker arm, preserving OE valvetrain geometry and balance while offering superior longevity and performance.
Rocker arms wear in conjunction with the camshafts, meaning the two must be replaced simultaneously. Aftermarket and performance camshaft options (Schrick, CAT-Cams, etc.) are typically ground from softer blanks and, as a result, cannot be used with factory rocker arms. We tested our performance cam followers with aftermarket camshafts to validate compatibility, ensuring smooth, reliable, and safe operation under demanding conditions.
Features:
Forged chromoly construction for maximum strength and durability Diamond-like carbon-coated surface reduces friction, extends service life, and permits compatibility with aftermarket and performance camshaft options Precision-ground tolerances ensure consistent and quiet operation OEM weight match maintains valvetrain balance and reliability Superior wear resistance for performance and endurance applications NOTE: Rocker arms are wear items and must be replaced alongside a new set of camshafts, regardless of profile or manufacturer. Installing a new set of rocker arms onto a used set of camshafts is NOT recommended.
Kit Contents:
24 DLC-Coated Rocker Arms (required to complete both camshafts) Product Development: Our Turner Performance Rocker Arms are the result of advanced engineering, testing, and quality assurance by Turner’s Research & Development team. Every stage of development employs FARO laser scanning, SolidWorks 3D CAD modeling, and in-house rapid prototyping for precise fitment and design validation. Performance and durability are proven through Mustang AWD 500 SE dyno testing and Superflow SF-750 Flowbench analysis, ensuring each component meets Turner’s uncompromising standards for performance and quality.
