Overview

"Sleep-er" (slang) A vehicle which has been internally modified while retaining a mostly stock appearance in order to fool opponents in a drag race, or to avoid the attention of the police.


This powerful kit by Zipper's transforms your 3.937" bore 107" M8-powered machine to 4.125" bore 117" with a simple piston swap in your provided cylinders. We first remove the dowels from the cylinders and machine the head gasket decks to ensure flatness and proper finish for positive MLS head gasket seal. The cylinders are then treated to the best precision boring and honing process you can find, as our technicians precisely measure each piston to provide skilled, old-fashioned sizing processes to the cylinders. Mounted in special torque plates, a CNC-hone is used to create a straight and true finish, topped off with brush-finish technology that requires minimal run time for ring seating while providing best power. Choose the Red Shift cam (468 Early Torque or 472 Balanced Power) that will provide the power output that best matches your riding style and we'll package it up with a new full compliment cam bearing, top end-cam chest gasket set along with a set of Quickee pushrods and covers to simplify reassembly. This is a hugely cost-effective way to increase the power of the Milwaukee-Eight® engine – with stock heads!

In compliance with ARB emissions laws, this product is not sold or shipped to California.
