UP-3750-INT-CRK $255 Internally Balanced Crankshaft
Our internally balanced 3.750” stroke crankshaft removes the external weight used for balancing to the inside and spreads evenly along the crankshaft. This decreases crank flex and snout deflection which provides a stronger and smoother running engine.
UP-3480-INT-CRK $255 Internally Balanced Crankshaft
Our internally balanced 3.480” stroke crankshaft removes the external weight used for balancing to the inside and spreads evenly along the crankshaft. This decreases crank flex and snout deflection which provides a stronger and smoother running engine. New HP Nodular Steel Crankshaft for greater strength and reliability.
UP-BAL-SR $295 Complete Balanced Assembly
Our competition balanced assembly provides a much smoother running engine, better throttle response and fuel economy. We equalize the weight of all rotating and reciprocating components, build the appropriate bob weights, and precision spin balance the crankshaft through the 8000RPM range. This insures less dynamic friction and more power and torque. Because any small imbalance multiplies with RPM, balancing can correct (In some cases) hundreds of pounds of effective imbalance which keeps the engine from fighting itself and relieves un-wanted stress on critical engine components.
UP-EXT-BAL-KIT-S $345 Needed for externally balanced engines.
These hand-picked quality components far exceed reliability requirements to provide a solid and reliable engine. High Performance Pro Street products are used to meet the demands of our street rod packages.
UP-INT-BAL-KIT-S $345 Needed for internally balanced engines.
These high quality components work to provide much less crankshaft harmonics than the factory counterparts and are much stronger to provide needed reliability. High Performance Pro Street products are used to meet the demands of our street rod packages.
