Shaft Cluster

The Jerico shaft cluster is a precision counter shaft assembly engineered for high-performance manual transmissions, specifically designed for drag racing, street rod builds, and extreme duty applications. As a critical internal component of Jerico transmission systems, this shaft cluster handles power transfer between gears with the durability required in full-throttle, rpm-limited environments where traditional OEM transmissions fall short. Whether you're building a supercharged engine or running nitrous oxide, the shaft cluster is the foundation upon which reliable gear engagement depends.

Manufactured from high-strength steel in its natural finish, the Jerico shaft cluster maintains dimensional precision across its 7.7-inch length and compact 2.05 x 1.55-inch cross-section to fit within tight transmission housings while maximizing gear tooth contact. The steel construction resists shock loading and thermal cycling—critical characteristics when dealing with instant torque spikes that occur at launch or during rapid gear changes. At 1.55 pounds, this component contributes minimal rotating mass, reducing parasitic drag and improving throttle response in time-critical competition scenarios.

This shaft cluster is ideal for racers, hot rodders, and transmission builders who demand OEM-quality components within a Jerico transmission platform. Installation requires professional transmission assembly skills and knowledge of proper bearing preload, thrust clearance, and gear backlash specifications. Compatibility is limited to Jerico transmission models engineered for this specific counter shaft configuration; cross-referencing your transmission casting number with Jerico technical documentation is essential before ordering. Each unit ships complete and ready for assembly into your high-performance transmission build.
