Description

The Screamin’ Eagle 4" Big Bore Bolt-On Cylinder and Piston Kit is a performance upgrade designed to increase engine displacement. This kit allows you to take a 96 or 103 cubic inch Twin Cam V-Twin motor to a full 110 cubic inches without removing the engine from the chassis. It achieves this by increasing the internal bore from 3-7/8” to 4” without altering the cylinder spigot's outside diameter, allowing the cylinder to slip into the existing case bore without modification. The kit includes front and rear cylinders, system-matched pistons with rings, and breathers.
