The BBM Hydraulic Roller Lifter Set .903 Dia Retro-Fit is designed for engine builders and performance mechanics looking to upgrade classic small-block and big-block applications. This lifter set is ideal for those who are rebuilding high-mileage engines or converting older blocks to roller technology, ensuring reliable valve actuation for consistent power delivery.
Featuring a .903-inch bore diameter, these hydraulic roller lifters are compatible with retro-fit installations and replace worn or stock components. The design includes internal oil passages and precision-machined bearing surfaces that automatically adjust valve lash through hydraulic pressure, eliminating the need for manual adjustments and reducing mechanical noise.
This lifter set is particularly beneficial for engine combinations where original hydraulic flat-tappet lifters have worn out or where a conversion to roller technology is desired without major block modifications. Weighing 6.51 pounds, it ships in compact dimensions, making it easy to transport and install for both shop and home mechanics.
