The T AND D MACHINE Rocker Shaft – BBM 440 is a precision steel rocker arm shaft designed specifically for Chrysler 440 engine builds. This component plays a crucial role in controlling valve actuation and ensuring optimal rocker arm geometry for various engine configurations. It is essential for both original restorations and modern high-performance rebuilds.
Manufactured by T&D Machine, this rocker shaft is made from high-quality steel, ensuring durability under the stresses of sustained valve train loads and thermal cycling. The BBM 440 designation indicates its compatibility with classic and stroker 440 Big Block engines. Proper diameter and hardness are critical to prevent deflection under high spring pressures and to evenly distribute loads across all rocker pedestals.
Engine builders and shops restoring or modifying Chrysler 440 engines will find this rocker shaft indispensable, especially when using aftermarket rocker arm ratios, stud girdles, and custom cylinder head configurations. It is vital to verify compatibility with your specific rocker arms and pedestal setup before ordering. The 440 Big Block platform remains a popular choice for classic car restorations and performance enhancements.
