The Balancer Shaft Removal kit is a must for high RPM performance. The QR25DE comes equipped with a balancer shaft assembly that spins at twice engine speed to generate an opposing inertial mass. While this contributes to a small decrease in the perceived vibration, it can double the stress on the main bearings, as this opposing mass must push the engine block in an opposing direction to the engines reciprocating mass. This is a bit like what happens when you clap your hands, only at the main bearings in your motor! That combined with the fact that the balance shafts would be spinning over 14000 RPM makes this kit a must for any QR25 performance engine.
