Milwaukee Eight Stage III Kit (above)

MILWAUKEE EIGHT STAGE III:

(Requires STAGE I Kit)

Next we go to the stage III kit also known as the big bore kit. This kit increases engine displacement allowing the engine to swallow more air and fuel, a higher compression piston squeezes the air and fuel mixture into a more volatile mixture and when combined generates more power. The stage III kit displacement increases are accomplished with larger cylinders, matching pistons and the proper cam up grade using your stock cylinder heads. 

UP TO A 35% INCREASE IN POWER!

Don’t think the stage III is enough power then the stage IV kit might be the way to go!

MILWAUKEE EIGHT STAGE IV: 

(Requires STAGE I Kit)

Now we are into ground pounding performance! This is the highest level performance up grade by Harley Davidson. The stage IV kit provides a maximum increase in displacement, compression and flow. Higher- flowing CNC ported cylinder heads and larger bore throttle body increase the velocity and feeds larger volumes of air and fuel into the engine. Which maximizes power on a larger displacement engine. Combines ported cylinder heads and larger throttle body in combination with cylinders, matching pistons and proper cam which equals an ground pounding combination!

UP TO A 45% INCREASE IN POWER!
