Hyd. Roller Lifters - BBM Retro-Fit

The Hyd. Roller Lifters - BBM Retro-Fit from HOWARDS RACING COMPONENTS represents a purpose-built solution for Mopar B and RB-series engine builders seeking to upgrade their valvetrain with modern hydraulic roller technology. This set of 16 lifters is engineered specifically for 426 Hemi engines and similar big-block Mopar platforms, allowing builders to retrofit existing engine blocks with superior roller lifter performance while maintaining compatibility with link-bar actuation systems. Street Series hydraulic roller lifters deliver improved durability, reduced friction, and extended component life compared to traditional flat-tappet designs.

Hydraulic roller lifters operate by utilizing oil pressure to automatically maintain zero lash while the roller design dramatically reduces camshaft and lifter wear. The 0.904-inch outside diameter profile integrates with link-bar actuation, a critical design feature that distinguishes this retrofit from other roller lifter conversions. Hydraulic design eliminates the need for manual lash adjustment and compensates for thermal expansion, making these lifters ideal for both street and strip applications where reliability and consistent valve timing are essential. The complete 16-piece set ensures proper coverage across the full valvetrain without mixing component ages or wear characteristics.

Builders working with Mopar B-block, RB-block, and 426 Hemi platforms will find this retrofit kit indispensable when transitioning from antiquated flat-tappet systems to modern roller technology. Installation requires proper block preparation and compatible rocker arm geometry, making this an ideal choice for comprehensive engine rebuilds rather than partial upgrades. Whether restoring a classic muscle car, building a stroker engine, or seeking reliable performance for street-driven applications, this hydraulic roller lifter set delivers the durability and precision that serious engine builders expect from HOWARDS RACING COMPONENTS.
