BBM Shaft Rocker Arm Kit 1.70/1.70 Ratio

The T and D Machine BBM Shaft Rocker Arm Kit with a 1.70/1.70 ratio is a precision component designed for marine engines that require high-performance valve actuation. This kit is essential for serious boaters and marine technicians who prioritize reliable power delivery and consistent performance on the water. It serves as a replacement for worn or stock components that can negatively impact engine efficiency and responsiveness.

The 1.70/1.70 ratio indicates the relationship between the camshaft movement and valve lift, ensuring optimal valve timing and lift characteristics. This design allows for precise and consistent valve opening across both intake and exhaust ports, providing a mechanical advantage while minimizing stress on valve train components. T and D Machine utilizes durable materials and precision machining to reduce deflection under load, maintaining the integrity of fuel and ignition curves.

This rocker arm kit is particularly beneficial for marine builders and experienced boaters looking to enhance engines that utilize BBM shaft architecture. It is designed for those aiming to maximize mid-range torque and top-end responsiveness while ensuring durability during demanding conditions. Proper installation is crucial for achieving the best performance from this 20-pound assembly.
