Shaft Rocker Arm Kit BBC 1.75/1.75 Ratio

The JESEL Shaft Rocker Arm Kit BBC 1.75/1.75 Ratio is designed for big-block Chevrolet engines, providing precision valve actuation for those seeking maximum reliability and consistent performance. This kit is ideal for serious engine builders and mechanics focused on valvetrain control, whether for street machines, race engines, or high-output performance builds.

Featuring a full roller rocker arm assembly, the kit minimizes friction losses at the pushrod interface, which helps reduce heat generation and extends component life during high-RPM operation. The shaft-mount design eliminates common deflection and wear patterns found in stud-girdle systems, ensuring consistent valve lift and duration across the RPM range. Precision manufacturing and premium materials contribute to repeatable valve events and reliable lifter loading.

This rocker arm kit is particularly beneficial for BBC engine builders working with 396, 402, 427, or 454 platforms, where valvetrain stability is crucial for power delivery and engine durability. Installation requires compatible shaft, pushrod, and lifter components, so it's essential to verify compatibility with your engine setup.
