The GM Ecotec Cloyes Short Chain Balance Shaft Delete Kit was developed for high RPM GM Ecotec racing engines where simplified oiling, reduced rotating mass, and improved reliability are important for sustained performance.

Factory balance shafts were originally designed to reduce vibration and improve comfort in OEM street vehicles — not for dedicated racing environments, sustained high RPM operation, aggressive cornering loads, or high horsepower performance applications.

As engine speed and load increase, the factory balance shaft assembly adds additional rotating mass, oiling complexity, chain load, and potential failure points that many racers and engine builders prefer to eliminate in serious competition engines.

The Cloyes Short Chain conversion replaces the factory balance shaft drive system with a simplified short chain oil pump configuration commonly used in high RPM Ecotec builds. This setup removes unnecessary rotating components while simplifying the lower end oiling system for improved durability and serviceability.

Unlike cut shaft or neutral balance shaft setups, the short chain system completely removes the factory balance shaft assembly and related rotating components for a cleaner and more complete racing conversion.
