On some late model GM engines, the balancer is a press fit instead of using a keyway to hold it in place. This works fine until a supercharger kit is added. The additional stress of the belt driven supercharger requires either a keyway be machined or the use a balancer pin kit, which is available from many speed shops.

The PowerBond™ by Dayco SS series uses the factory balance weights; The race balancer is for engines with zero balance. If you need help choosing the correct balancer for your engine build, please contact the Dayco tech team at (800) 848-7902 for advice and part numbers.

You’ll want to replace the balancer if you notice excessive vibration, crankshaft oil leaks, or deteriorated rubber.

The Dayco Underdrive and overdrive balancers are a great way to increase the performance of your factory supercharged car. These balancers feature pulleys that are either larger or smaller than the factory supercharger pulley. Spinning the supercharger faster will increase the amount of supercharger boost pressure and in turn, increase the horsepower of the engine. Installing these pulleys does require professional dynamometer calibration of the…

It’s best practice to change both components at the same time because they usually wear out at the same pace and if one fails or is failing, the other is likely not far behind it. They are both part of the same system and need to function at optimal levels as well.

It could be. The water pump is responsible for the cooling system and pulling heat away from the engine. If the pulley is loose or if you notice signs of a leak around the water pump’s weep hole, it’s time for a change. Be sure however that when replacing the water pump, you also drain, flush and refill the cooling system with the OE specified coolant…
