BBC Mech Roller Lifter Set +.300 O/C

The BBC Mech Roller Lifter Set +.300 O/C is designed for big-block Chevrolet engines that require precise valve actuation with a +.300-inch over-center offset. This lifter set is ideal for high-performance and racing applications, providing enthusiasts with the durability and consistent lift geometry they need for optimal engine performance.

Constructed from hardened steel, these mechanical roller lifters feature precision-machined rollers that minimize wear and maximize energy transfer to the pushrods. The roller design significantly reduces friction compared to flat-tappet lifters, allowing for reliable valve control at elevated RPMs and improved overall engine efficiency.

This lifter set is particularly beneficial for those building street performance engines, competition motors, or restoration projects within the 396, 427, and 454 displacement range. Proper installation and break-in procedures are essential to ensure optimal performance and longevity of the lifters.
