Precision Works Balance Shaft Eliminator Kit - Ecotec Cavalier Sunfire Cobalt HHR

Manufactured from billet CNC blocks - this balance shaft elimination kit is used to delete the shafts from the 2.0L, 2.2L, and 2.4L Ecotec engines.  By removing the balance shaft, it allows the engine to rev much faster and safely rev higher.

Our kit is complete with two idlers and two aluminum bushings, while other kits may require you to cut the stock shafts which can be dangerous and costly.

Features:

• Manufactured from brand new cores.
• No core exchange needed or any additional cost.
• Precision CNC machined to meet or exceed OEM spec.
• The idlers replace the stock shafts, allowing you to retain the OEM chain that drives the water pump.
• Removes roughly 9 lbs. from the rotating assembly.

Installation Note:

• These must be pressed into the block to seal the oil passages left by removing the shafts.
• Once the kit is installed, this can not be removed due to the bushings being pressed into the block.
• Installation instruction is not provided, and we recommend that the installation to be done by a professional shop.
