Rotating assembly consist of the crankshaft, connecting rods, pistons and rings. Butler Performance doesn't simply install or sell rotating assemblies out of the box. Most suppliers and builders simply "box balance" based on manufacturer supplied weights.

We don't take anyone else's word when it comes to the parts we stand behind. We put all rotating assemblies through the Butler Process for quality and performance. Our internal balancing process ensures each part of the kit is put through a multi-step inspection process. We then weigh and pin fit the rods and pistons as needed. We computer balance the crankshaft to the rest of the assembly. This process ensures that all the parts of the assembly are matched to form a "Butler Performance" worthy assembly. We then document all weights and information on a balance card that ships with the assembly.
