SBC 8.0in Balancer Ext. Balance Non-SFI

The SBC 8.0in Balancer Ext. Balance Non-SFI from PRO-RACE PERFORMANCE PRODUCTS is a specialized harmonic balancer designed specifically for small-block Chevy engines that require extended balance correction. This component is particularly beneficial for enthusiasts building high-performance street and strip engines, especially those utilizing forged or high-compression setups where OEM balancers may not suffice.

This 8.0-inch balancer features an external balance configuration, allowing for counterweights to be positioned on the outer hub. This design enables machine shops to add or adjust balance weights to match the specific crankshaft's rotating assembly weight, effectively reducing vibration and stress on main bearings and crankshaft journals. The non-SFI designation indicates that this balancer is suitable for street and bracket racing applications, where it meets different standards than those required for professional drag racing.

Builders working with small-block Chevy platforms—including 283, 327, 350, 400, and 427 variants—will find this balancer provides the necessary flexibility during engine assembly and dyno tuning. Its design allows for precise reciprocating mass compensation, ensuring optimal engine longevity and power delivery. This makes it an excellent choice for those seeking cost-effective performance tuning in naturally aspirated and moderately boosted builds.
