Ecotec Outer Balance Shaft Delete Bushings (Set of 2)

The BK Racing Ecotec Outer Balance Shaft Delete Bushings are designed to properly seal the outer balance shaft bores during GM Ecotec balance shaft delete conversions.

When removing the factory balance shaft assembly, the outer sprocket-side bores must be properly sealed to maintain correct oil control and prevent oil leakage. These precision-machined bushings provide a clean and reliable solution for properly completing the outer portion of the balance shaft delete system.

Designed specifically for GM Ecotec engines, the BK Racing Outer Delete Bushings are manufactured for accurate fitment and secure installation in demanding racing and high-performance applications.

These bushings are commonly used in high RPM Ecotec builds where racers and engine builders simplify the oiling system by removing the factory balance shaft assembly. Learn More
