BBM Shaft Rocker Arm Kit - 1.6/1.6 Ratio

The BBM Shaft Rocker Arm Kit - 1.6/1.6 Ratio is a precision-engineered component designed specifically for high-performance Mopar Indy 440-1 and 440-C engines. This kit is ideal for serious engine builders and enthusiasts who require reliable valve actuation in both naturally aspirated and modified configurations.

Constructed from aerospace-grade aluminum and finished in natural anodize, this rocker arm kit features a full roller tip design that minimizes friction and wear on valve stems during continuous operation. The shaft-mount configuration distributes load across a rigid pedestal system, eliminating deflection common in stud-mounted alternatives and ensuring consistent valve timing across the entire RPM range.

This kit is particularly beneficial for builders restoring or modifying Indy 440 single-shaft engines where OEM rocker geometry has become worn or where performance upgrades demand enhanced valve control. Installation requires compatible pushrods, valvetrain geometry confirmation, and familiarity with Mopar B/RB-series engine architecture.
