Things you must know

You must have a frame that can accept an engine 5/8” taller than a stock Evo. You must have heavy-duty drive train components. Limited warranty. Rated Power: is based on using a very large bore Carb such as the 48mm Mikuni or S&S D series and Hooker Step Tuned Short Staggered Dual Ex. Other Combinations will change the power level attainable 


Machined In U.S.A. Cast-in steel inserts guaranteed not to move. Large bore breather for increased crank case vacuum and less blow by. 1/2” Alignment dowels for true line bore. Counterbored stainless allen head case bolts. Close machining tolerances. Made from prime C355-T6 aluminum that is superior in strength to A356. Styling and cosmetic machining for a custom look. 


Our New state of the art designed crankshaft incorporates a massive 1.670 diameter pin that is pressed into the one piece, heat treated, 4140 steel flywheel half making these crankshafts some of the strongest available on the market today. These crankshafts feature all new 8.0” long H-Beam rods with .927 diameter wrist pins to handle all the power you can throw at them. These are also balanced using our exclusive methods making these some of the smoothest engines in the industry.
