KITS FOR 2007-UP TWIN CAM® ENGINES
Factory 2007-up Twin Cam® engines are equipped with 4-3/8” stroke crankshafts. The factory cylinder bore size of 3-3/4” yields the 96” displacement, which was gradually increased to 3-7/8” starting in 2010 for 103” displacement. We can turn your 96” engine into either a 103 or a 107”, and your 103 into a 107” simply by resizing the factory cylinders.
