Banshee Crankshafts
Cranks from +5mm to +10mm are forged cranks made by Crank Works. The cranks in sizes +10mm to +20mm are Crank Works manufactured with billet crank webs. These larger strokes produce much more power and demand a stronger crank, hence the use of a billet crank. These cranks are available with any rod length, and 72mm "big" bearings are also an option. All cranks come trued, welded, and balance.
*Note: Geisick Performance also recommends the use of TZ bearings on all high performance engines. Any crank larger then +4mm stroke requires case trenching, or modification. To insure proper balancing for your specific application indicate the size of pistons you are using when ordering the crank.

The cranks we offer for the stock to +4mm stroke sizes are Hot Rod cranks. These have been a proven and reliable crank for many years. They are available in stock replacement with standard rods, or long rods. Hot Rods also offer a +4mm crank (with either standard or +5mm rod lengths) which will fit into a banshee crank case with out any modification.
